Figure 12-4: Definition of ports E, F, G, H
The properties of the combined ports are as follows:
●
The signal direction (input or output) is according to the configuration of ports A, B,
C, and D. E.g. to write data to port G (H), ports A, B, and C (A, B, C, and D) must
be configured as output ports.
●
Data can be read and written using the
CONTrol:HANDler:E|F|G|H[:DATA]
commands.
●
The bit order is D3 ... D0 C3 ... C0 (port E), B7 ... B0 A7 ... A0 (port F), C3 ... C0
B7 ... B0 A7 ... A0 (port G), and D3 ... D0 C3 ... C0 B7 ... B0 A7 ... A0 (port H).

ZNB's internal Handler I/O option R&S
ZN-B14 is placed in the right-hand
part of the network analyzer's rear panel. It must be installed by a Rohde & Schwarz
service representative.
The external Handler I/O option R&S
ZNBT-Z14 can simply be connected to the Digital
I/O connector at the rear panel of the R&S
ZNBT.
The pin assignment of the connector is shown below. A slash (/) at the beginning of the
signal name indicates that, by default, it is an active low (negative logic) signal.
