I am trying to capture the transmit waveform from an X10 controller.
I have channel A linked to the 50Hz zero crossing timebase, nice squarewave there.
The X10 output is a series of 1mS pulses coinciding with the ZC transitions.
Here's the issue. I want to capture the entire transmission sequence, which is basically a mark/ space code, and typically takes 50 ZC events (about 0.4s) to transmit.
I set the scope to trigger off B channel transition as I want to capture from start of signal (which is 3 marks). The scope captures over multiple frames, but its not clear that these are continuous from one another in time, or whether when one frame is finished, it waits to re-trigger, and if it is doing this then it will lose any sequential spaces because they won't cause a transition.
i.e. what I want is to trigger the scope and have it record everything (or lack of) for the next 0.5 secs.
What's a recommended setting for this? And is there a way to confirm the capture time is continuous rather than separate windows which might themselves be separated in time.
yeah yeah I could read the manual but forums are where the experts reside
