How can I ChipSHOUTER pattern trigger with hardware trigger?

EM signal pattern was occurred well when I push ‘pulse’ button in front of ChipSHOUTER.

But, just one EM pulse signal was occurred when I use hardware trigger with 1V and 1us pulse signal.

Followings are some part of my setting:
…
cs.pat_enable = 1
cs.pat_wave = ‘00000000000001111111111111111000000000000001111111111111000000000001111111111111’
cs.hwtrig_mode = True
cs.hwtrig_term = False
…

Hi,

There’s two different trigger routes - the hardware trigger, which basically hooked up directly to control the output, and the software trigger, generated by a microcontroller. The microcontroller is what handles the wave pattern, so the pattern will have no effect when using a hardware trigger. If you’re able to, you could replicate the pattern you want on the trigger signal and it should have a similar effect.

Thank you for your reply.

You mean that ChipSHOUTER can not use pattern with hardware trigger, is it?

It’s a bad news for me.^^
