Meas Setup
3, when CALCulate:CDPower:SRATe=960000
1, when CALCulate:CDPower:SRATe=1920000
Initial S/W Revision
Prior to A.02.00
Mod Scheme (BTS Only)
Sets the modulation scheme.
•
Auto: The specified channel by Symbol Rate and Code Number is considered to be modulated by auto-
detected scheme.
•
QPSK: The specified channel by Symbol Rate and Code Number is considered to be modulated by
QPSK.
•
16QAM: The specified channel by Symbol Rate and Code Number is considered to be modulated by
16QAM.
•
64QAM: The specified channel by Symbol Rate and Code Number is considered to be modulated by
64QAM.
Key Path
Meas Setup
Mode
WCDMA
Remote Command
:CALCulate:CDPower:MTYPe AUTO|QPSK|QAM16|QAM64
:CALCulate:CDPower:MTYPe?
Example
CALC:CDP:MTYP QAM16
CALC:CDP:MTYP?
Notes
W-CDMA HSPA option needs to be installed and enabled. Otherwise, this parameter is not available
and SCPI commands for Modulation Scheme do not have effect.
To select “QAM64”, W-CDMA HSPA+ option needs to be installed and enabled. Otherwise the
softkey for 64QAM is unavailable and the SCPI command to select “QAM64” is not valid.
You must be in W-CDMA mode to use this command. Use :INSTrument:SELect to set the mode.
Dependencies
This key is displayed and active when Device is BTS
and
Symbol Rate is 240 ksps.
This key is displayed but inactive when Device is BTS
and
Symbol Rate is
not
240 ksps. In this case,
the last setting (Auto/QPSK/16QAM/64QAM) is displayed on the menu key even though the “QPSK”
setting is always used.
This key is not displayed when Device is MS. Instead, the I/Q Branch menu key is displayed and
active.
Preset
AUTO
State Saved
Saved in instrument state.
Range
Auto|QPSK|16QAM|64QAM
