  1. Because the ScanScreen and ShiftScreen acquisition modes ignore triggers, how do I know precisely when they start the first acquisition? Is it possible to start the analog and digital scan-acquisitions simultaneously to ensure that both data streams are reading/displaying with a common time axis? Or do I misunderstand how these types of acquisition work? My previous approach was to generate a slow pulse and use the rising edge as a trigger to simultaneously start single acquisitions on both analog and digital scopes, then plot and repeat on the next pulse. But this is tedious, I can't g
  2. Hi, and thanks for the support so far. After a lot of experimenting and reading the help, I'd like to understand the "envelope" of possible triggered, repeated, logged acquisitions, which can run unattended for days or weeks. We need to leave a system in an inaccessible location and log at least 4 analog channels with at least 100 KHz sample rate, for a time of at least 100 usec after the trigger occurs for each triggered event. We believe these events have a time frame of 5 or so 60 Hz cycles, so that's 85 msec post-trigger and we'd like a cycle or two (16 or 32 msec) of pre-trigger. These ev
  3. I am sending synchronized, phase-shifted pulses with the AWG on both AnalogOut channels on the Discovery2, using a custom application I'm writing in python. I am feeding the AnalogOut directly back to the AnalogIn with no additional hardware involved. I am trying to read the two AWG signals using the AnalogIn channels, but I can't get Channel 2 to report the signal. Instead, both signals are adding together and displaying as coming from channel 1, with the expected channel 2 signal showing up as negative voltages on channel 1. How do I separate the two signals? This is the chunk o
