Capture 0006 [20260417_113037] — FALSE ALARM

YES
+
+The LP-low plateau at ~108 ns comfortably exceeds the 50 ns SN65DSI83 requirement, so that alone would not cause a missed SoT. However, the LP exit → HS transition duration of only 3 ns is critically below the 50 ns minimum specification, meaning the LP-01/LP-00 state machine likely completed too fast for the bridge's LP receiver to properly detect and latch the SoT sequence. Additionally, the HS amplitude of only 28 mV is far below the normal 105–122 mV range and falls under the 50 mV "absent" threshold, indicating the bridge almost certainly failed to achieve differential lock on the HS data. The combination of an essentially undetectable LP-to-HS transition and absent HS signaling amplitude makes this a genuine flicker event where the SN65DSI83 missed the packet entirely.

Capture 0010 [20260417_114925] — FALSE ALARM

YES
+
+The LP-low plateau of 6.9 ns is dramatically below the SN65DSI83's 50 ns minimum detection threshold, and the LP exit-to-HS transition of only 1 ns confirms the LP-01/LP-00 SoT preamble states were essentially absent. Additionally, the HS amplitude of 43 mV is well below the normal 105–122 mV range and falls under the 50 mV "absent" threshold, indicating the bridge almost certainly failed to lock onto the HS data burst. Taken together — a near-nonexistent LP-low plateau, sub-spec LP exit timing, and collapsed HS amplitude — this is a textbook case of a missed SoT that would cause visible flicker on the display.

Capture 0013 [20260417_115424] — FALSE ALARM

YES
+
+The HS amplitude of 33 mV is critically low—well below the SN65DSI83's differential detection threshold (normal range 105–122 mV), meaning the bridge almost certainly cannot reliably decode the HS data burst even if SoT is detected. Additionally, the LP exit → HS transition of only 2 ns is far below the required 50 ns minimum, indicating the LP-01/LP-00 preamble states are effectively absent or too brief for the bridge's LP receiver to register the start-of-transmission sequence. While the LP-low plateau itself measures 108 ns (above the 50 ns threshold), the combination of a near-absent LP exit duration and severely attenuated HS amplitude strongly indicates the SN65DSI83 either missed the SoT entirely or cannot recover valid data from this burst, making visible flicker virtually certain.

Capture 0031 [20260417_120132] — FALSE ALARM

YES
+
+The LP-low plateau of 108 ns meets the ≥50 ns requirement, but the LP exit→HS transition of only 3.4 ns is critically below the 50 ns minimum specification. This means the LP-01 and LP-00 states that constitute the SoT preamble are essentially absent or far too brief for the SN65DSI83 to properly detect and synchronize to the start-of-transmission. Additionally, the HS amplitude of 30.5 mV is well below the normal 105–122 mV range and falls under the 50 mV "absent" threshold, indicating the bridge almost certainly failed to lock onto the HS data burst. The combination of a near-instantaneous LP exit and effectively absent HS signaling makes this a genuine flicker event.

Capture 0041 [20260417_120537] — FALSE ALARM

YES
+
+The LP-low plateau of 12.9 ns is dramatically below the SN65DSI83's required ≥ 50 ns minimum, giving the bridge only ~26% of the time it needs to reliably detect the LP-01/LP-00 SoT preamble. The LP exit-to-HS transition of just 3.2 ns further confirms the LP-01 and LP-00 states are essentially being skipped, making SoT detection virtually impossible. Additionally, the HS amplitude of 87 mV is below the normal 105–122 mV range, which compounds the problem by reducing the bridge's ability to lock onto the HS data even if it did somehow detect the truncated SoT. All three anomalies together make this a high-confidence flicker event.

Capture 0058 [20260417_121236] — FALSE ALARM

YES
+
+The HS amplitude of 31 mV is critically low — well below the SN65DSI83's differential receiver threshold (normal range 105–122 mV, and flagged absent at <50 mV) — meaning the bridge almost certainly cannot resolve valid HS data even if the SoT were properly detected. Additionally, the LP exit → HS transition of only 4 ns is far below the 50 ns minimum specification, indicating the LP-01/LP-00 preamble states were too brief for the bridge's LP receiver to reliably detect the start-of-transmission sequence. While the LP-low plateau itself measured 108 ns (adequate), the combination of a near-absent LP exit duration and severely attenuated HS amplitude means the SN65DSI83 will either miss the SoT entirely or fail to decode the subsequent HS burst, resulting in visible flicker.

Capture 0059 [20260417_121318] — FALSE ALARM

YES
+
+The LP-low plateau of 108 ns meets the ≥50 ns requirement, but the LP exit → HS transition of only 3 ns is critically below the 50 ns minimum specification. This means the LP-01/LP-00 SoT preamble states were not held long enough for the SN65DSI83 to properly detect the start-of-transmission. Additionally, the HS amplitude of 30 mV is far below the normal 105–122 mV range and falls under the 50 mV "absent" threshold, indicating the bridge almost certainly failed to lock onto the HS data. The combination of a nearly instantaneous LP exit and effectively absent HS signaling makes this a clear flicker event.

Capture 0065 [20260417_121555] — FALSE ALARM

YES
+
+The HS amplitude of only 24 mV (single-ended) is critically below the normal 105–122 mV range and well under the 50 mV threshold for a valid HS signal — the SN65DSI83 almost certainly cannot reliably detect or decode HS data at this level. Additionally, the LP exit-to-HS transition time of only 3 ns is far below the 50 ns specification minimum, indicating the LP-01/LP-00 preamble states were essentially absent or too brief for the bridge's LP receiver to properly recognize the SoT sequence. While the LP-low plateau itself measured 108 ns (above the 50 ns requirement), the combination of a near-absent LP exit duration and severely attenuated HS amplitude means the bridge very likely missed this transmission entirely, producing a visible flicker event.

Capture 0080 [20260417_122200] — FALSE ALARM

YES
+
+The LP-low plateau of 22 ns is less than half the SN65DSI83's required ≥ 50 ns minimum for reliable SoT detection, and the LP exit-to-HS transition of only 1 ns confirms the LP-01/LP-00 preamble states were essentially absent. With these timing violations, the bridge almost certainly failed to recognize the start-of-transmission, causing it to miss the subsequent HS burst. The HS amplitude of 126 mV indicates the transmitter did drive a valid HS burst, so the data was sent but the bridge had no properly-timed SoT to latch onto, which is the classic mechanism for visible flicker on this platform.

Capture 0089 [20260417_122821] — FALSE ALARM

YES
+
+The LP-low plateau is completely absent (reported as `None` / 0 ns), far below the SN65DSI83's 50 ns minimum requirement for SoT detection. Additionally, the HS amplitude is only 0.5 mV—effectively zero against the normal 105–122 mV range—confirming that no valid HS data burst was established after the LP exit. The combination of a missing LP-01/LP-00 preamble and absent HS signaling means the bridge almost certainly failed to recognize the start-of-transmission, which would produce a visible flicker or blank frame on the display.

Capture 0092 [20260417_125020] — FALSE ALARM

YES
+
+The HS amplitude of 23 mV is critically low — well below the SN65DSI83's differential detection threshold (normal range 105–122 mV, and flagged absent at <50 mV). This means the bridge almost certainly cannot resolve valid HS data from this burst, regardless of LP timing. Additionally, the LP exit → HS transition of only 3 ns is far below the 50 ns minimum required for the bridge to properly detect the LP-01/LP-00 SoT preamble states, even though the LP-low plateau itself measured 108 ns. The combination of an essentially absent HS signal and a grossly non-compliant LP exit timing makes it virtually certain the SN65DSI83 missed this SoT, resulting in visible flicker.

Capture 0095 [20260417_125144] — FALSE ALARM

YES
+
+The HS amplitude of 28 mV is critically low—well below the SN65DSI83's differential detection threshold (normal range 105–122 mV, and flagged absent at <50 mV)—meaning the bridge almost certainly cannot reliably detect the HS data burst even if the LP sequencing were perfect. Additionally, the LP exit → HS transition of only 2 ns is far below the 50 ns minimum specification, indicating the LP-01/LP-00 preamble states are essentially absent or too brief for the bridge's LP receiver to properly parse the SoT sequence. While the LP-low plateau itself measures 108 ns (above the 50 ns threshold), the combination of a virtually nonexistent LP exit duration and an HS amplitude so low it qualifies as "absent" makes it nearly certain the SN65DSI83 missed this SoT, resulting in visible flicker.

Capture 0098 [20260417_125316] — FALSE ALARM

YES
+
+The HS amplitude of only 24 mV (single-ended) is critically below the normal 105–122 mV range and well under the 50 mV "absent" threshold, indicating the HS data burst was essentially not received by the SN65DSI83. Additionally, the LP exit-to-HS transition time of just 2 ns is far below the 50 ns minimum specification, meaning the LP-01/LP-00 states were too brief for the bridge to properly recognize the SoT sequence. Although the LP-low plateau itself measured ~108 ns (adequate), the combination of a nearly absent HS burst and a grossly non-compliant LP exit duration means the bridge almost certainly failed to lock onto this transmission, resulting in a missed frame and visible flicker.

Capture 0101 [20260417_125442] — FALSE ALARM

YES
+
+The LP-low plateau itself at 108 ns is adequate (≥ 50 ns), but the LP exit-to-HS transition of only 3 ns is critically below the 50 ns minimum specification. This means the LP-01 and/or LP-00 states that form the SoT preamble are essentially absent or too brief for the SN65DSI83 to reliably detect, even though the overall LP-low region measured long enough. Additionally, the HS amplitude of 38 mV is far below the normal 105–122 mV range and falls under the 50 mV "absent" threshold, indicating the bridge almost certainly failed to lock onto valid HS data. Taken together — a 3 ns LP-exit violating the 50 ns spec and a sub-threshold HS amplitude — this capture strongly represents a genuine flicker event where the SN65DSI83 missed the SoT.

Capture 0104 [20260417_125605] — FALSE ALARM

YES
+
+The critical issue here is the **LP exit → HS transition time of only 3 ns**, which is far below the 50 ns minimum required by the SN65DSI83. While the LP-low plateau itself measures 108 ns (above the 50 ns threshold), the 3 ns LP-exit duration indicates the LP-01/LP-00 preamble states are essentially absent or too brief for the bridge to properly detect the SoT sequence. Additionally, the **HS amplitude of 36 mV** is drastically below the normal 105–122 mV range and falls below the 50 mV "absent" threshold, meaning even if the bridge detected SoT, the HS data would be unreadable. The combination of a collapsed LP-exit transition and effectively absent HS signaling makes it nearly certain the SN65DSI83 missed this transmission, causing visible flicker.

Capture 0105 [20260417_125642] — FALSE ALARM

YES
+
+The LP-low plateau of 108 ns is above the 50 ns threshold, but the LP exit → HS transition time of only 1 ns is critically below the 50 ns minimum specification. This means the LP-01/LP-00 states were essentially absent or too brief for the SN65DSI83 to properly detect the SoT sequence. Additionally, the HS amplitude of 34 mV is far below the normal 105–122 mV range and falls under the 50 mV "absent" threshold, indicating the bridge almost certainly failed to lock onto the HS data burst. The combination of a near-zero LP exit duration and effectively absent HS signaling strongly indicates a missed SoT event that would produce visible flicker.

Capture 0114 [20260417_130019] — FALSE ALARM

YES
+
+The HS amplitude of 22 mV is critically below the normal 105–122 mV range and well under the 50 mV "absent" threshold, indicating the HS data burst was essentially not driven or not properly received. Additionally, the LP exit → HS transition time of only 2 ns is far below the 50 ns minimum specification, meaning the LP-01/LP-00 preamble states were too brief for the SN65DSI83 to reliably detect the Start-of-Transmission. Although the LP-low plateau itself measures 108 ns (above the 50 ns threshold), the combination of an effectively absent HS burst and a collapsed LP-exit duration strongly indicates the bridge failed to lock onto the SoT sequence, making visible flicker virtually certain.

Capture 0119 [20260417_130226] — FALSE ALARM

YES
+
+The HS amplitude of 28 mV is critically below the normal 105–122 mV range and well under the 50 mV threshold, indicating the HS data burst was essentially absent or undetectable by the SN65DSI83 receiver. Additionally, the LP exit → HS transition of only 2 ns is far below the 50 ns minimum specification, meaning the LP-01/LP-00 preamble states were not held long enough for the bridge to recognize the SoT sequence. Although the LP-low plateau itself measured ~108 ns (above the 50 ns threshold), the combination of a near-zero HS amplitude and a 2 ns LP-exit duration strongly indicates the bridge failed to lock onto the HS burst, resulting in a missed frame and visible flicker.

+The HS amplitude of only 26 mV (well below the normal 105–122 mV range and under the 50 mV "absent" threshold) indicates the HS data burst was essentially not driven or severely attenuated, meaning the bridge almost certainly could not recover valid data from this packet. Additionally, the LP exit → HS transition of only 2 ns is far below the 50 ns minimum specification, indicating the LP-01/LP-00 preamble states were truncated to the point of being undetectable by the SN65DSI83. Although the LP-low plateau itself measured 108 ns (above the 50 ns threshold), the combination of a near-absent HS burst amplitude and a critically short LP-exit-to-HS transition strongly suggests the bridge missed this SoT entirely, resulting in a dropped frame and visible flicker.

+The HS amplitude of only 26 mV is far below the normal 105–122 mV range and falls under the 50 mV "absent" threshold, indicating the HS data burst was essentially not driven or severely attenuated—this alone would cause the SN65DSI83 to fail to decode the video packet. Additionally, the LP exit → HS transition time of only 2 ns is well below the 50 ns minimum specification, meaning the LP-01/LP-00 SoT preamble states were too brief for the bridge's LP receiver to reliably detect the start-of-transmission. Although the LP-low plateau itself measured 108 ns (above the 50 ns threshold), the combination of a near-absent HS signal and a critically short LP-exit duration strongly indicates the bridge missed or could not properly lock onto this HS burst, resulting in a visible flicker event.

This means the LP-01/LP-00 preamble states were essentially absent or collapsed into a single transient that the SN65DSI83 cannot reliably detect as a valid SoT sequence. Additionally, the HS amplitude of ~20 mV is far below the normal 105–122 mV range and falls under the 50 mV threshold, indicating the bridge almost certainly failed to lock onto the HS data burst.

Additionally, the HS amplitude of 31 mV is far below the normal 105–122 mV range and falls under the 50 mV "absent" threshold, meaning the SN65DSI83 likely cannot reliably sample the HS data even if it did detect the SoT. The combination of a virtually instantaneous LP-exit transition and an abnormally low HS swing strongly indicates the bridge missed or failed to lock onto this transmission, making visible flicker highly probable.

+Although the LP-low plateau itself measures 58.7–59 ns (above the 50 ns minimum), the LP exit → HS transition duration is only 1.7–2 ns, far below the 50 ns spec minimum. This means the LP-01/LP-00 states that form the SoT preamble are essentially absent or too brief for the SN65DSI83 to reliably detect. Additionally, the HS amplitude of 40 mV is well below the normal 105–122 mV range and falls under the 50 mV "absent" threshold, indicating the bridge likely never locked onto the HS data.

Additionally, the LP exit → HS transition time of just 1 ns is dramatically below the 50 ns minimum specification, meaning the LP-01/LP-00 SoT preamble states were essentially absent or too brief for the bridge's LP receiver to register the start-of-transmission. Although the LP-low plateau itself measured 108 ns (above 50 ns), the combination of a near-zero LP-exit duration and severely attenuated HS signaling strongly indicates the bridge missed this packet, producing a visible flicker event.

Additionally, the LP exit-to-HS transition of only 3 ns is far below the 50 ns minimum specification, indicating the LP-01/LP-00 states were essentially absent or too brief for the bridge's LP detector to properly sequence through the SoT preamble. While the LP-low plateau itself measured ~108 ns (above 50 ns), the combination of a near-absent LP exit duration and severely attenuated HS amplitude makes it virtually certain the bridge failed to lock onto this transmission, resulting in visible flicker.

Additionally, the **HS amplitude of 32 mV** is well below the normal 105–122 mV range and falls under the 50 mV "absent" threshold, indicating the bridge almost certainly did not lock onto the HS data burst. These two defects together — an essentially absent LP-to-HS transition time and a sub-threshold HS swing — mean the SN65DSI83 would miss the start-of-transmission, producing a visible flicker event.

Additionally, the HS amplitude of 40 mV is critically low—below the 50 mV "absent" threshold and far under the normal 105–122 mV range—indicating the bridge almost certainly failed to lock onto the HS data burst. Together, these three failures (insufficient LP-low dwell time, near-zero LP-to-HS transition, and sub-threshold HS swing) make it virtually certain the SN65DSI83 missed this SoT, resulting in a dropped video line or frame and visible flicker.

Together, these two violations mean the SN65DSI83 almost certainly missed this start-of-transmission event. While the HS amplitude (118 mV) and LP-11 voltage (1.014 V) are within normal bounds—indicating the PHY itself is electrically healthy—the timing of the LP signaling sequence is critically deficient, making visible flicker on this frame highly likely.

Although the LP-low plateau itself measures 108 ns (above spec), the bridge needs to see distinct LP-01 and LP-00 states each held for adequate duration, and the 4 ns LP exit time indicates these states are being blown through too rapidly for reliable detection. Additionally, the **HS amplitude of 33 mV** is drastically below the normal 105–122 mV range and falls below the 50 mV "absent" threshold, meaning even if the bridge did detect SoT, the HS data would be unreadable.
