Hi,
I know this is similar to my last thread, but I thought I would start a new one to get the header more specific to the question.
I want to use an arbitrary waveform generator to provide an external clock to the UFO and CWLite boards (I’m having an oscilloscope in parallel, and want to synchronize the whole system). However, I can’t get it to work. The AWG outputs a 10 MHz square wave from 0 to 3V. I have set the jumper settings on J3 so as to “pretend” to be the crystal oscillator. I have connected the square waveform to pin 2 (no jumper though), and a jumper on HS1 (pins 3-4). The scope.clock
settings are
scope.clock.adc_src = 'extclk_x1'
scope.clock.extclk_freq = 10000000
target.baud = target.baud*(10/7.37)
but the output becomes
I got this to work with the external oscillator, btw. Any idea what might be wrong? Has anyone else successfully used an external AWG clock source?
Thanks!
