SEND
Use the "SEND" button to send the previously defined command, e.g. before starting
the sweep for the related channel.
On a R&S ZN-B15/Z15 var. 03, before the command is executed the related shunt
resistance is set to its minimum possible value.
Remote command:
CONTrol<Ch>:RFFE<Bus>:COMMand:SEND (write-only) or
CONTrol<Ch>:RFFE<Bus>:COMMand:SEND? <BytesToRead> (with read-back)
RFFE interface voltage and current measurements
Defines the voltage and current measurements on the RFFE pins.
●
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).
Output Voltage
Defines the output voltages for the voltage/current measurements on the RFFE pins.
Note: The Data and Clock pins always use the same output voltages; their values can-
not be set independently.
The "Output Voltage" and Range / Shunt settings do not take effect until Set is
pressed.
Remote command:
CONTrol<Ch>:RFFE<Bus>:TEST:DATA
CONTrol<Ch>:RFFE<Bus>:TEST:CLOCk
CONTrol<Ch>:RFFE<Bus>:TEST:VIO
Range / Shunt
Defines the current range for the voltage and current measurement on the respective
RFFE pin. The analyzer firmware automatically selects a suitable shunt resistance.
The Output Voltage and "Range" / "Shunt" settings do not take effect until Set is
pressed.
