82357A USB / GPIB Interface

The Agilent 82357A is an adapter that creates a GPIB Interface from one of your unused PNA USB ports.


The 82357A can be used to connect a GPIB device using the PNA USB for any PNA application. In addition, the 82357A can be used to connect a power meter for a source power calibration.

Installing the 82357A USB/GPIB Interface

  1. Download and install firmware PNA revision 3.0 or greater. To check the revision of your PNA firmware, click Help then About Network Analyzer.

  2. Upgrade to the latest Agilent IO libraries from the CDROM that was shipped with the 82357A.  If not available, download them from www.Agilent.com (search for 82357A)

Configure the 82357A USB/GPIB Interface

When the 82357A is connected to the PNA USB, the following dialog box appears:

Normally, you do NOT need to edit these settings. The 82357A USB/GPIB Interface is configured automatically as the next unused VISA interface. This is usually GPIB2 unless you have already configured it for another purpose.

If the VISA Interface Name appears as GPIB0 or GPIB1, these Interfaces must be returned to their default settings for the 82357A to work properly with the PNA. See Configure for VISA / SICL to learn how.
