Frequency Control Mode

This parameter sets the RF analyzer frequency control mode, either Auto or Manual. When set to Manual, you can specify the RF analyzer frequency.

SCPI command: RFANalyzer:CONTrol:FREQuency:AUTO:GCALibration[?]

Frequency

This parameter sets the RF analyzer (receiver) frequency.  

SCPI command: RFANalyzer:MANual:FREQuency:GCALibration[?]

Band

This parameter sets the GSM/GPRS band. The test set's RF source and RF analyzer are automatically set to the appropriate frequencies for the band you specify.   

SCPI command: TRANsceiver:BAND:GCALibration[?]

ARFCN

This parameter sets the ARFCN for the currently selected GSM/GPRS band.

SCPI command: TRANsceiver:CHANnel(:DCS|:EGSM|:GSM450|:GSM480|:GSM750|:GSM850|:PCS|:PGSM|:RGSM)[?]

Power Control Mode

This parameter sets the RF analyzer's expected input power control mode, either Auto or Manual. When set to Manual, you can specify the RF analyzer expected input power for each uplink burst.

SCPI command: RFANalyzer:CONTrol:POWer:AUTO:GCALibration[?]

Uplink Bursts

This parameter sets which uplink burst is measured for single slot measurements on dual uplink PDTCHs.

SCPI command: RFANalyzer:BURSt[:UPLink][?]

Expected Power Burst 1

This parameter sets the power level in dBm that the test set's RF analyzer is expecting the wireless device first uplink burst to transmit at. The Power Control Mode parameter must be set to Manual to use this parameter.

SCPI command: RFANalyzer:MANual:POWer[:AMPLitude]:BURSt([1]|2):GCALibration[?]

Expected Power Burst 2

This parameter sets the power level in dBm that the test set's RF analyzer is expecting the wireless device second uplink burst to transmit at. The Power Control Mode parameter must be set to Manual to use this parameter.

Burst 2 is not applicable to GSM TCH measurements.

SCPI command: RFANalyzer:MANual:POWer[:AMPLitude]:BURSt([1]|2):GCALibration[?]

MS TX Level Burst 1

This parameter sets the traffic channel wireless device burst 1 uplink power control level for the currently selected GSM/GPRS band.   

SCPI command: RFANalyzer:MS:TXLevel[:SELected]:BURSt([1]|2)[:SELected][?]

MS TX Level Burst 2

This parameter sets the traffic channel wireless device burst 2 uplink power control level for the currently selected GSM/GPRS band.

Burst 2 is not applicable to GSM TCH measurements.

SCPI command: RFANalyzer:MS:TXLevel[:SELected]:BURSt([1]|2)[:SELected][?]

Expected Burst Type

This parameter sets the expected burst type that is used for measurement synchronization. (If it is not set, the test set may not synchronize to the input signal's midamble.)

SCPI command: RFANalyzer:BURSt:TYPE[:SELected][?]

EGPRS

This parameter sets whether the expected signal type is EGPRS. This controls the configuration of the test set's receiver. If any burst modulation commands are set to 8PSK then this parameter is automatically set On.

SCPI command: RFANalyzer:CONFig:EGPRs[?]

Modulation Type Burst 1

This parameter sets the modulation format for burst 1.

SCPI command: RFANalyzer:MODulation[:FORMat]:MANual:BURSt[1][?]

Modulation Type Burst 2

This parameter sets the modulation format for burst 2.

SCPI command: RFANalyzer:MODulation[:FORMat]:MANual:BURSt2[?]
