Hi Izzy123,
If you are using LabVIEW or CVI to interact with the device, I recommend taking a look at our Instrument Drivers. You can download the
871xB Instrument Driver for free from our website, and it includes a number of VIs functions and over 30 examples programs located in \LabVIEW\instr.lib\hp871xb\hp871xb.llb.
If you choose to stick with the Agilent driver, I recommend contacting Agilent for more information. In addition, the commands you are looking for are device specific, so if none of the examples address the issue, you may want to consult the user manual for the specific commands.
Regards,
