R&S ZNB/ZNBT
Range / Shunt
"Range" defines an upper bound of the current to be measured on the respective GPIO
pin. The analyzer firmware automatically selects a suitable shunt resistance.
Possible ranges for ports 1 to 8 are { 2·10
For a R&S ZN-B15/Z15 Var. 03 with FPGA version 6.1.0 or higher, Pins 9 and 10 can
be configured as follows:
●
0 A "high resistance" range (shunt resistance 100 MΩ)
●
100 mA range (shunt resistance 1 Ω)
For older versions, pins 9 and 10 have the same current range as pins 1 to 8.

Remote command:
CONTrol<Ch>:GPIO<Port>:RANGe
CONTrol<Ch>:GPIO<Port>:SHUNt?
Meas
Starts the voltage and current measurement.
Note that "Start Meas" does not automatically activate the "Voltage" and "Range" /
"Shunt" settings of the current channel. Use
The measurement (=sampling) time can only be set via remote command. It is not
channel-specific and applies to RFFE and GPIO measurements.
Remote command:
CONTrol<Ch>:GPIO:SENSe:TRIGger
CONTrol<Ch>:GPIO:TIME
Voltage, Current
Results of the voltage/current measurements on the related GPIO pins.
Remote command:
CONTrol:GPIO<Port>:SENSe:VOLTage?
CONTrol:GPIO<Port>:SENSe:CURRent?
CONTrol:GPIO:SENSe:SUMCurrent?
5.12.1.6 Sweep Sequencer
Defines the RFFE commands to be executed and the GPIO voltages to be applied
before each sweep (segment).
