Implement repetitive timed capture

[abrilevskiy]

Hello,

Could you please let me know if it is possible to set up repeated capture with an interval or have pauses during capture?
The use cases: analysis of relatively high-frequency signals that slowly changed over time, for example, blinking LEDs with fade in/out PWM based. PWM frequency is kHz, which leads to have sample rate of at least 10x higher at the same time fade-in/out might take seconds which requires a capture duration of to be 5-10+ seconds. The process could be: capture 1000 samples with a sample rate of 50kHz, pause for 100ms, repeat capture 1000 samples with a sample rate of 50kHz, and so on for 20 seconds.

Thank you!

Right now there is no such functionality, but if you are debugging your own device and still have a pin and a timer free you can do it:

• Create a repetitive timer that triggers each second.
• On the timer handler set the pin to high for at least the duration of one cycle but no more than 999 cycles.
• Use the pin as trigger for the analyzer.
• Set the burst mode to capture as you need.

In any case, this is quite interesting and I don't think it should be too difficult to implement so I'm going to change the name of the issue and assign it as an enhancement and possibly on the next version it will be available.
