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

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
R&S
ZN-Z15 or
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.

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-
plete, the handler will remove and replace the device and sort it into pass/fail bins. For
details, refer to
Chapter 11.3.4, "Handler I/O (Universal Interface)"
