●
The measurement parameters are channel-specific. However only one configura-
tion can be measured at a time.
●
Voltage and current measurements on the RFFE and GPIO pins are only possible
with Var. 03 of the extension board R&S ZN-B15/-Z15 (part number 1323.9355.03
or 1325.5905.03).
The high-resistance configuration of GPIO pins 9 and 10 requires FPGA version
6.1.0 or higher. For older versions of the R&S ZN-B15/Z15 Var. 03, pins 9 and 10
have the same current range as pins 1 to 8 (see "Range / Shunt" on page 664).
To check for an equipped RFFE/GPIO interface's part number and "Product Index"
version, see the Hardware tab of the "Info" dialog.
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
n
μA | n=1,...,5 }.
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.
The Voltage / Output Voltage and "Range" / "Shunt" settings do not take effect until
Apply is pressed.
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 Apply to activate them manually.
