Fixed

I have found that setting the output impedance AFTER configuring the waveform can mess up the offset and amplitude values depending on their previous values. Changed it so that this is done before and it all works consistently now. The comms freeze is due to manually clearing the USB buffer before e...

Hi, Using the programming commands, is there any way to toggle the output on/off digitaly, rather than using the generators output relays each time? i.e. not using OUTPut1:STATe ON/OFF. The only solution I have found so far is setting it to continuous mode when I want the outputs to be on and then s...
