Yes – purge is set to true.
The VSG waveform for now is short – it’s the simple CW waveform (iq = complex(1, 0) ) from the MATLAB examples in the SDK. The elapsed time from the start of transmitting the waveform from the VSG to returning from the GetIQData function (calling bbGetIQUnpacked and converting the returned array to complex) is < 0.20 seconds, so I’d think I wouldn’t need a separate thread just yet… But I’ll investigate doing it if I have to.
I’ve made the attached script just about as simple as I can get it. I’ve allowed for up to 4 triggers when grabbing I/Q data.
