ZN-B15/-Z15 Var. 03
Controls the channel-specific setup of the two RFFE bus interfaces and GPIO ports
provided by
variant 03
of the internal/external RFFE GPIO extension board R&S
ZN-

If the R&S
ZNB is equipped with
variant 02

Background information
Refer to
Chapter 4.7.19, "RFFE GPIO interface"
For more details about the voltage range, clock frequency ranges and their steps sizes,
refer to
Chapter 12.3.5, "RFFE - GPIO interface"
RFFE tab
The "RFFE" tab is divided into two parts:
●
The upper part gives access to the RFFE interface settings and allows manual
command execution and result display (see
"Basic RFFE interface settings and
●
The lower part allows you to define and apply test voltages and to execute voltage
and current measurements on the RFFE pins (see
"GPIO voltage and current mea-
The "Set" button activates the "Output Voltage" and "Range" ("Shunt" resistance) set-
tings. The "Meas" button starts the voltage and current measurements.
