CALL:AWGNoise:POWer
CALL:AWGNoise:POWer[:SAMPlitude][:SELected]
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[:CELL]:POWer” ) are absolute power levels and make up the
total forward channel RF output power. Depending on the cell power setting, an AWGN level may
be within the range listed below but cause an error message to be displayed. Possible causes are:
• Sum of AWGN and cell power causing total RF power limits to be exceeded (see
“CALL:TOTal:POWer[:AMPLitude][:SELected]?” for the allowable range of total RF power.)
• Greater than 10 dB difference between cell power and AWGN.
• Amplitude offset causing total RF power limits to be exceeded (see
“SYSTem:CORRection:GAIN” to set or query the amplitude offset value).
Setting Range: -170 dBm/1.23 MHz to +35dBm/1.23 MHz, NAN
Resolution: 0.01 dB
Query Range: -170 dBm/1.23 MHz to +35 dBm/1.23 MHz, NAN
Resolution: 0.01 dB
*RST Setting NAN
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.
