GPIB Command Conventions

CALL:AWGNoise[:INTernal]:POWer[:SAMPlitude]<[:SELected]|:DIGital856>

Function

The setting form of this command performs two functions: (1) sets the additive white gaussian noise (AWGN) level and (2) turns the AWGN on/off state to on. The query form returns the desired AWGN power level. (See Cell Power, AWGN (Additive White Gaussian Noise) Power and Total RF Power for more information about desired versus current power levels).

The optional [:SELected] keyword in this command specifies that the cell power level being set or queried applies to the current system type (see System Type ).

Requirements

Test Application Revision: A.01.20 and above
Lab Application Revision: A.01 and above

Setting

Range/Resolution: see CALL:AWGNoise[:INTernal]:POWer:AMPLitude<[:SELected]|:DIGital856>

Query

Range/Resolution: see CALL:AWGNoise[:INTernal]:POWer:AMPLitude<[:SELected]|:DIGital856>

*RST Setting

OFF, and see CALL:AWGNoise[:INTernal]:POWer:AMPLitude<[:SELected]|:DIGital856>

Programming Example

 
OUTPUT 714;"CALL:AWGNoise:POWer -30"
! Sets AWGN power state to ON and
! sets desired AWGN power level to -30 dBM/1.23 MHz for the current system type.
OUTPUT 714;"CALL:AWGNoise:POWer:DIGital856 -54"
! Sets AWGN power state to ON and
! sets AWGN power level to -54 dBm/1.23 MHz for the DIGital856 system type.

CALL:AWGNoise[:INTernal]:POWer:AMPLitude<[:SELected]|:DIGital856>

Function

Sets/queries the desired additive white gaussian noise (AWGN) level. (See Cell Power, AWGN (Additive White Gaussian Noise) Power and Total RF Power for more information about desired versus current power levels).

The optional [:SELected] keyword in this command specifies that the AWGN power level being queried applies to the current system type (see System Type ).

Requirements

Test Application Revision: A.01.20 and above
Lab Application Revision: A.01 and above

Setting

Range: -170 dBm/1.23 MHz to +35 dBm/1.23 MHz (this is the range of settings accepted, see Cell Power, AWGN (Additive White Gaussian Noise) Power and Total RF Power for the actual hardware range of the source)

Resolution: 0.01 dB

Query

Same as setting

*RST Setting

-54 dBm/1.23 MHz

Programming Example

 
OUTPUT 714;"CALL:AWGNoise:POWer:AMPLitude -30"
! Sets the desired AWGN power level to -30 dBM/1.23 MHz for the current system type.

CALL:AWGNoise[:INTernal]:POWer:STATe<[:SELected]|:DIGital856>

Function

Sets/queries the additive white gaussian noise (AWGN) state.

The optional [:SELected] keyword in this command specifies that the AWGN power level being queried applies to the current system type (see System Type ).

Requirements

Test Application Revision: A.01.20 and above
Lab Application Revision: A.01 and above

Setting

Range: 1|ON|0|OFF

Query

Range: 1|0

*RST Setting

OFF

Programming Example

 
OUTPUT 714;"CALL:AWGNoise:POWer:STATe ON"
! Turns on AWGN for the current system type.
