I'm attempting to control a Tektronix PWS4205 programmable DC power supply using the LabVIEW samples that came with the driver. Eventually I want to program the cycle On/Off time of the voltage output to a motor while logging current over time.
My current issue:
The VISA resource name for the instrument is displayed in the control. When I attempt to run any of the example VIs or just the Initialize.vi I am unable to communicate with the instrument.
Error displayed:
The ID Query failed. This may mean that you selected the wrong instrument or your instrument did not respond. You may also be using a model that is not officially supported by this driver. If you are sure that you selected the correct instrument and it is responding, try disabling the ID Query.
I am able to use SignalExpress to output voltage and measure current on the power supply, but not when using example VIs. I'm not sure why I can communicate using the same VISA resource name in SignalExpress, but not through the VI.
