The RF Generator tab on the RF Control window provides access to the RF Generator (source) parameters.
This parameter sets the RF generator frequency control mode, either Auto or Manual. When set to Manual, you can specify the RF generator frequency.
SCPI command: RFGenerator:CONTrol:FREQuency:AUTO:TCALibration[?]
This parameter sets the DPCH channel number when the Control Mode is set to Auto.
SCPI command: TRANsceiver:CHANnel:TCALibration[?]
This parameter sets the RF generator frequency when the Control Mode is set to Manual.
SCPI command: RFGenerator:FREQuency:TCALibration[?]
This parameter sets the RF generator power level.
SCPI command: RFGenerator:POWer:AMPLitude:TCALibration[?]
This parameter sets the RF generator modulation mode. The following selections are available:
Continuous wave (CW)
Amplitude modulation (AM)
Frequency modulation (FM)
Double sideband suppressed carrier (DSB-SC)
Arbitrary waveform generator (ARB)
SCPI command: RFGenerator:MODulation:TCALibration[?]
This parameter sets the RF generator modulation frequency. This setting only applies when the Modulation Mode is set to AM, FM, or DSB-SC.
SCPI command: RFGenerator:MODulation:FREQuency:TCALibration[?]
This parameter sets the RF generator AM depth. This setting only applies when the Modulation Mode is set to AM.
SCPI command: RFGenerator:MODulation:AM:DEPTh:TCALibration[?]
This parameter sets the RF generator FM deviation. This setting only applies when the Modulation Mode is set to FM.
SCPI command: RFGenerator:MODulation:FM:DEViation:TCALibration[?]
This parameter sets the arbitrary waveform (ARB) file from the ARB random access memory (RAM) disk directory. This setting only applies when the Modulation Mode is set to ARB.
When a file is selected it is loaded into the ARB memory so that it can be run.
The following waveforms are available:
TD-SCDMA_RMC12.2_MC
This waveform comprises of 8 frames, each of which includes TS0 (timeslot
0), DwPTS and TS4 (timeslot 4):
DwPTS phase pattern in first 4 frames uses S2 while DwPTS phase pattern in last 4 frames uses S1.
TS0 and TS4 has the same channel configurations, including:
Multi-code: codes 0 and 1 with SF = 16
Maximum midamble shift = 8
Midamble shift index = 1
Total power of all codes to DwPTS = -6 dB
TD-SCDMA_RMC12.2_SC
This waveform comprises of 8 frames, each of which includes TS0 (timeslot
0), DwPTS and TS4 (timeslot 4):
DwPTS phase pattern in first 4 frames uses S2 while DwPTS phase pattern in last 4 frames uses S1.
Channel configuration in TS0 is as follows:
Multi-code: codes 0 and 1 with SF = 16
Maximum midamble shift = 8
Midamble shift index = 1
Total power of all codes to DwPTS = -6 dB
Channel configuration in TS4 is as follows:
Single-code: code 1 with SF = 8
Maximum midamble shift = 8
Midamble shift index = 1
Power offset to DwPTS = -6 dB
TD-SCDMA_TS0
This waveform comprises of 8 frames, each of which only includes TS0
(timeslot 0):
Channel configuration in TS0 is as follows:
Multi-code: codes 0 and 1 with SF = 16
Maximum midamble shift = 8
Midamble shift index = 1
Total power of all codes to DwPTS = -6 dB
SCPI command: RFGenerator:AWAVeform:SELection[?]
This parameter sets the ARB run mode. This setting only applies when the Modulation Mode is set to ARB. Setting this command to:
Run starts running the ARB file from the beginning.
Stop provides no output and turns the TSP IF off.
SCPI command: RFGenerator:AWAVeform:RUN[?]
This parameter sets the external ARB output trigger. The external trigger drives the rear panel BBP TRIG OUT BNC connector. This setting only applies when the Modulation Mode is set to ARB.
SCPI command: RFGenerator:AWAVeform:TRIGger:EXTernal[:OUTput][?]
This parameter sets the RF output port destination: RF In/Out or RF Out Only.
SCPI command: RFGenerator:OUTPut[:DESTination][?]
