Diagnostics Tab (new)
Sends an ST 2110 test signal from an output and measures it when it comes back on an input: audio/video sync, dropped or repeated frames, and audio gaps or clicks. The test picture is color bars with a white box that flashes once a second, with a short audio burst at the same moment. Use it to test a signal path through a switch, router or other device and back.
| Term | Definition | User Action or Effect |
| Output column | Card, video output and audio output that send the test signal. The preview shows what is sent. | Choose outputs that are set up in Senders & Receivers and not in use. An output in use is never taken over: the message 'OUT x in use. Choose a free output that is set up in Senders & Receivers.' appears. |
| Input column | Card, video input and audio input that receive the signal back. The preview shows what arrives. | The input must be set up to receive what the output sends, through the path under test. |
| Genlock line | Gray text under Card, for example Genlock SMPTE 2059 (PTP), Locked, 1080p 50. | Read-only. |
| Format | Picture format of the test signal. | Formats outside the genlock's frame-rate family are grayed out. The test never changes the genlock. |
| Channels | Audio channels in the test signal: 2, 4, 8 or 16. | Set to match the path. |
| Burst on channel 1 too | Also puts the audio burst on channel 1. | Tick when the path carries only one channel. |
| Measure for / Until stopped | How long the sync test runs, in minutes, or until Stop. | Set before starting. |
| Warm-up | Seconds at the start that are not measured. | Lets the equipment under test settle. |
| Notes | Description of the test, for example 'Studio 2 router, path B'. | Shown at the top of the results. |
| Signal from another generator | Measures a test signal from somewhere else; this card's generator does not start. | Tick when another device sends the signal. |
| Start generator | Sends the test signal on the output only. | Use when another device measures, or you need a known signal. |
| Start sync test | Sends the test signal and measures it on the input. | The status shows 'warming up' first; measuring starts after the warm-up time. |
| Stop | Stops the generator or the test. | Stopping a sync test opens the results. |
| Test results | Opens the results of the last test. | Save PDF, Save HTML and Save JSON keep a copy (suggested folder: Documents\QuickLink\ST2110 Diagnostics). |
Generator running: Sending on names the outputs; Generator Running with Late 0 and Errors 0 is normal.
| Reading | What it tells you | Good result |
| Offset, Mean | How far audio is from video. + means audio is late. | Close to 0 ms is best. |
| Range, Drift | How much the offset moves during the test, and per hour. | Small values are best. |
| Dropped frames, Repeated, Out of order | Lost, doubled or misordered video frames. | 0 is expected. |
| Mixed fields, Field order swaps | Problems with interlaced formats such as 1080i. | 0 is expected. |
| Test picture | Whether the test picture arrived. | found is expected. |
| Tone, Gaps, Clicks, Discontinuities | Level of the test tone, and breaks, clicks or jumps in the audio. | A steady level and 0 events are expected. |
Not working: Video flow and Audio flow show No stream, Test picture shows 'not found on the input' and the offset stays at 'waiting for a flash and burst'. The generator is working, so check the input addresses and that the network passes the stream. On one card, the input's primary port receives what the output's redundant port sends.
The results window never says pass or fail. It shows the EBU R 37 reference for comparison: audio no more than 40 ms early or 60 ms late.
