4.7.16 GPIB interface

Option R&S ZNB/ZNBT-B10

This hardware option provides a GPIB bus connector according to standard IEEE 488 /

IEC 625 (GPIB). The GPIB bus interface can be used for controlling the R&S ZNB/

ZNBT from an external controller.

For interface details, refer to Chapter 12.3.3, "GPIB interface", on page 1541.

Remote Control of External Devices via GPIB

The current hardware of the R&S ZNB/ZNBT-B10 does not support GPIB bus control-

ler mode, i.e. the B10 cannot be used to control external devices via GPIB.

If you want to use GPIB to control external devices from the R&S ZNB/ZNBT, you have

to use an additional USB-to-IEC/IEEE adapter.

4.7.17 Device control

Option R&S ZNB/ZNBT-B12

This option provides a PCIe and a Direct Control interface, both intended to control

external devices.

●

The PCIe interface is suitable for certain Rohde & Schwarz Signal Generators.

●

The Direct Control interface is a proprietary interface for Rohde & Schwarz VNA

extensions such as the external RFFE GPIO interface R&S ZN-Z15 or External

switch matrices R&S ZN-Z8x.

A suitable cable is available with option R&S ZN-B121.

Direct Control of Switch Matrices

The Direct Control interface allows you to establish a direct connection between the

VNA measurement bus and the FPGA controlling the routes of a switch matrix

R&S ZN-Z8x. This bypasses the matrices' microcontroller and significantly reduces the

switching times compared to management via USB or LAN.

4.7.18 Handler I/O (universal interface)

Option R&S ZN-B14 / R&S ZNBT-Z14

A network analyzer that is equipped with a Handler I/O (Universal Interface), can inter-

act with an external part handler. The digital control signals on the interface connector

indicate the possible start and the end of a measurement, as well as a global limit

check result. Typically, the handler will insert the device to be tested into a test fixture

and provide a trigger pulse to initiate the measurement. After the measurement is com-
