●
Make sure that the required RFFE bus interfaces and GPIO ports are enabled by
setting the respective "Seq." flags in the "RFFE Config" dialog (see
interface settings and command execution"
ration).
●
The sequencer settings are only valid for the active channel. In a multiple channel
measurement, you have to configure each channel separately.
●
On a R&S ZN-B15/Z15 var. 03, the sweep sequencer overwrites the currently
applied voltages and sets the related shunt resistances to the minimum possible
value (see
"GPIO voltage and current measurements"
Proceed as follows:
1. For segmented sweeps, select the related sweep segment (see
on page 559).
2. Use the "Add" or "Insert" button to add a new step to the command/switch
sequence - either at the end of the existing sequence or above the selected step,
respectively.
3. Make the appropriate settings in the sweep sequencer table:
a) Define the RFFE commands ("RFFE" columns).
b) Set the GPIO voltages ("GPIO" columns).
c) Specify the delays between subsequent commands/switches and before the
4. Use "Delete" to remove the selected item or "Delete All" to clear or the command/
switch sequence.
5. Select "OK" to apply the settings. To discard the changes, select "Cancel" .
Range
For segmented sweeps, a command/switch sequence can be defined for each sweep
segment. For unsegmented sweeps, only a single "Range" is available.
Remote command:
Unsegmented sweeps
CONTrol<Ch>:SEQuence:COUNt?
CONTrol<Ch>:SEQuence:CLEar:ALL
Segmented sweeps:
CONTrol<Ch>:SEGMent<Nr>:SEQuence:COUNt?
CONTrol<Ch>:SEGMent<Nr>:SEQuence:CLEar:ALL
RFFE columns (sweep sequencer table)
The cells in the "RFFE" columns define the sequence of commands to be sent over the
respective RFFE interface. The command definition dialog (opened from the ellipsis
buttons) is described in
on page 553.
