Steps 

1.

 

Connect the USB cable to the rear 
panel USB B port.  

 

 

2.

 

Change the Rear panel-USB (F-22) 
setting to USB-CDC (2).

Configure GPIB Interface  

To use GPIB, the optional GPIB to USB (2260B-GPIB-USB) adapter 
must be used. Only one GPIB address can be used at a time. 

 

Configure GPIB 

1.

 

Ensure the 2260B is off before proceeding. 

 

2.

 

Connect the USB cable from the rear panel  
USB B port on the 2260B to the USB A port on 
the GPIB to USB adapter. 

 

3.

 

Connect a GPIB cable from a GPIB controller to 
the GPIB port on the adapter.
