The R&S
ZNB/ZNBT can be equipped with a GPIB (IEC/IEEE) bus interface (option
R&S
ZNB/ZNBT-B10. The interface connector labeled "GPIB" is located on the rear
panel of the instrument. The GPIB bus interface is intended for remote control of the
R&S
ZNB/ZNBT from a controller.
Characteristics of the interface
