CALL:AWGNoise

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 AWGN power level or NAN.

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

AWGN and cell power (see CALL:POWer ) are absolute power levels and make up the total forward channel RF output power.

The return value for this query is not necessarily the AWGN power level being transmitted by the test set at the moment this command is processed by the test set. It may return a value that the test set has been requested to transmit, but that has been pended or delayed for some reason. See Troubleshooting Setting Power Levels for possible causes. To query the AWGN power level the test set is transmitting at the moment the command is sent, use the CALL:STATus:AWGNoise[:INTernal]:POWer[:AMPLitude][:SELected]? command.

Setting

Range:

• -170 dBm/1.23 MHz to +35 dBm/1.23 MHz, 9.91 E+37
  (-120 dBm/1.23MHz to -15 dBm/1.23 MHz actual hardware range with amplitude offset = 0)
  
  The actual power range is defined by adding the value of the associated Amplitude Offset to the range shown above. See Cell Power, AWGN Power and Total RF Power Ranges .

Resolution: 0.01 dB

Query

Range: Same as setting range.

Resolution: 0.01 dB

Programming Example

 
OUTPUT 714;"CALL:AWGNOISE:POWER:SAMPLITUDE -30" !Sets the AWGN power level to -30 dBM/1.23 MHz and turns the state on.

*RST Setting

Programming Example

 
OUTPUT 714;"CALL:AWGNOISE:POWER:AMPLITUDE -30" !Set the AWGN level to -30 dBM/1.25 MHz.

Function

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

The return value for this query is not necessarily the AWGN power state at the moment this command is processed by the test set. This command may return a state that has been requested of the test set, but that has been pended or delayed for some reason. See Troubleshooting Setting Power Levels for possible causes. To query the AWGN power state of the test set at the moment, use the CALL:STATus:AWGNoise[:INTernal]:POWer:STATe[:SELected]? command.

The optional [:SELected] keyword in this command specifies that this query applies to the current system type.

Programming Example

 
OUTPUT 714;"CALL:AWGNOISE:POWER:STATE:SELECTED ON" !Turns on AWGN.
