82357B USB / GPIB Interface

The Keysight 82357B is an adapter that creates a GPIB Interface from one of your unused VNA USB ports.


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

Installing the 82357B USB/GPIB Interface

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

  2. Download the Keysight IO libraries from http://www.keysight.com/find/iolib.

Configure the 82357B USB/GPIB Interface

When the 82357B is connected to the VNA USB, the driver is automatically installed.

Normally, you do NOT need to edit these settings. The 82357B USB/GPIB Interface is configured automatically as the next unused VISA interface. Keysight Connection Expert allows you to change the setting.

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