I am trying to connect to a B1500a using Keysight connection expert. I am using a gpib-usb-hs cable from NI and have the NI drivers to interface with cable and Keysight connection expert 2020. The active light is on (orange) on the NI connector. I have attached a picture of the Keysight connection interface. Does anyone know if the b1500a is supported by keysight connection expert/ how I can interface with it? Let me know if you need any other information.
