Hi,

Apologies in advance if this is a very basic question

On a Siglent SDS6000A scope. I understand how one can use Sequence mode to capture a specified number of pulses on one channel

However what I want to do is use pulses on one channel as the trigger event to capture pulses on two other channels as well so that I can review their relative timing

Can this be done with Sequence mode of should I just set the memory depth very low and use normal History mode to revew the pulses across the three channels?

Thanks

In sequence mode, all active channels are stored in the memory simultaneously in time with the trig channel. So you can observe and measure their relative timing (just like in normal operation).
Of course, for full time resolution it requires that the detail to be compared on the time scale of each channel is located in the same segment.

The time correlation between channels can also be checked across segments because each segment has a time stamp. However, the resolution of the timestamp is only 1us.

In addition, the condition is that the comparable details are not located in the blind time between the segments.
When comparable events occur in the same segment, full-time resolution is naturally available.

rf-loop,

Thank-you so much for this!!!

All of the example videos I watched on Sequence mode only showed one channel being recorded so I (wrongly) assumed that's all one could do

Much appreciated :-)

This is not SDS6000A but Sequence works same (in all Siglent models where is this feature, same principle)
Also I have used SDS6000 other version so I also know it instead of only believing. ;)

Here very simplistic example.

I take single shot 5000 segment sequence. (in this case I use it in single shot mode)



image a1
After 5000 segments captured it have stopped and all segments are stacked to this image after sequence ready and processed for image. But because repetitive signal they are overlaid.
If there is some anomaly in some individual segments it can also see here. But here not anomalies, just continuous signals from generator..




image a2
I want go to history for look these individual segments




image a3
Individual segment (no 4995)
Here in history can of course use automatic measurements, math, cursors... even serial decode. 
And in history data is real ADC data...   there can also change interpolation and also look only sample dots if want.
Siglent save full data to segments, just same as in normal oscilloscope use.
Time stamps can look in delta time or real time mode.
 
Also there can use full window pan and  zoom and split window zoom when look segments in History.
