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-
