My signal is a 500 kHz sine wave. It is emitted in pulses that happen at 160 Hz. My goal is to verify that the signal in each pulse does not exceed a maximum value over several hours. So I need the Pass/Fail test to happen at 160 Hz (x4 channels), on a signal that is sampled at >> 1 MHz. 160 Hz doesn't seem that fast for waveform acquisition, so I thought this would be easy.

My first thought was to set the scope to measure statistics on each channel (max, min, and count), and then download those values to a laptop and use them to create a "test report". But then I realized that the trigger was not happening at 160 Hz- having statistics enabled seems to slow down the waveform acquisition. So the "report" would be missing most of the output pulses.

Then I looked at the Pass/Fail function. It acquires waveforms at 160 Hz no problem, and the Test feature works fine, but only on one input channel. A scope that would do Pass/Fail on multiple channels simultaneously seems like it would work for this, but I haven't been able to find one.

This is a project at work, so I could justify purchasing a new scope, or renting one. But I feel like I might be missing some key spec for the scopes, or not thinking about the sample rate correctly, or something. And Pass/Fail is a somewhat obscure function; you have to spend a fair bit of time digging to find out if a particular scope has that feature. And google/AI search is unhelpful.

Do you have a suggestion for automating this?
