Appendix A SCPI Command Reference
RFGenerator subsystem
436 WCDMA Options Version 6.20
– The RF generator and analyzer are enabled using the appropriate
:CONFigure:CSYStem command.
:RFGenerator:WCDMa:STATe
:RFGenerator:WCDMa:LEVel
:RFGenerator:WCDMa:FREQuency
Syntax
:RFGenerator:WCDMa:STATe <PredefExp>
Parameters
PredefExp
is one of the following predefined expressions: ON|OFF.
Default is OFF.
Description
Switches the RF generator ON
or OFF.
While the Willtek 4400 is in RF generator mode, there is no signalling active. This
means that the Willtek 4400 may be used as RF signal generator for all kinds of RF
and WCDMA signals. While working as a RF generator, the Willtek 4400 does not
respond to any messages sent by the mobile nor does the test set expect the mobile
under test to react in any way.
Query
The query form of this command returns the current setting. A query will return a
string, containing one of the predefined expressions explained above.
Example
:RFG:WCDMA:STAT ON
:RFG:WCDMA:STAT?
Value returned in this example "ON"
.
Syntax
:RFGenerator:WCDMa:LEVel <real1>
Parameters
real1 is a floating point real number.
The minimum value for real1 is -120.0, the maximum value is -20.0. The min-
imum resolution for real1 is 0.1. The default value for real1 is -60.0.
Description
This command sets the RF output power level of the Willtek 4400. The value speci-
fied for real1 is the power output level in dBm.
Query
The query form of this command will return the current setting. The string delivered
will contain one floating point real number.
Example
:RFG:WCDMA:LEV -50.5
:RFG:WCDMA:LEV?
Value returned in this example:
-50.5.
Syntax
:RFGenerator:WCDMa:FREQuency <real1>
Parameters
real1
is a floating point real number.
The minimum value for real1 is
430,000,000, the maximum value is
2,300,000,000. The minimum resolution for real1 is 10. The default value for
real1 is 800,000,000.
Description
This command sets the RF generator's frequency. The value specified for real1 is
the output frequency in Hz.
Note: For more details on the WCDMA frequency ranges, please refer to section Basic
Specifications of WCDMA Bands.
Query
The query form of this command will return the current setting. The string delivered
back will contain one floating point real number.
