I want to measure the current by the Agilent34901A channel21 or 22. The HP34901A installed on the Agilent34970A is connected to the computer via GPIB Bus. Does anyone have the subvi for this measurement?
If you have the 34970A driver from NI, open HP34970A EZ Voltage.vi. On the diagram, the first string you'll see is "MEAS:VOLT:". Change this to "MEAS:CURR:". Save the modified VI as HP34970A EZ Current.vi. If you want, you can add this VI to HP34970A Single Point.vi just by adding an item to the "Function" slider and adding a new case.
