5.7.11 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.
5.7.12 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)", on page 1387.
5.7.13 RFFE GPIO Interface
Internal: Option R&S ZN-B15 (R&S ZNB only)
External: Option R&S ZN-Z15
The trend in mobile radio communication is towards higher scale of integration of exter-
nal components such as filters, switches, low noise and power amplifiers. The require-
ment for test and measurement equipment is to make it possible to control those com-
ponents directly from the instrument without the need of additional external tools, e.g. a
USB to RFFE adapter.
For these kinds of applications, Rohde & Schwarz has developed an RFFE-GPIO
extension board for the R&S ZNB/ZNBT. This board is equipped with a 25-pin female
connector interface providing 2 independent RF Front-End (RFFE) interfaces accord-
