CALL:AWGNoise:POWer
CALL:AWGNoise:POWer:AMPLitude[:SELected]
Function Sets/queries the additive white gaussian noise (AWGN) level.
The optional [:SELected] keyword in this command specifies that the AWGN power level being
queried applies to the current system type. At this time there is only one system type choice,
DIGital2000. Specifying DIGital2000 will have the same effect as using the optional [:SELected]
keyword.
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 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: -120 dBm/1.23 MHz to -15 dBm/1.23 MHz, NAN
Resolution: 0.01 dB
Query Range: -120 dBm/1.23 MHz to -15 dBm/1.23 MHz, NAN
Resolution: 0.01 dB
*RST Setting NAN
Programming Example
OUTPUT 714;"CALL:AWGNOISE:POWER:AMPLITUDE -30" !Set the AWGN level to -30 dBM/1.25 MHz.
