Programming Examples
Example: Generating a pure noise signal
The following example generates a pure noise signal with specified bandwidth and
noise level.
SOURce1:AWGN:MODE ONLY
SOURce1:AWGN:BWIDth 3840000
SOURce1:AWGN:BWIDth:RATio 2
SOURce1:AWGN:STATe ON
SOURce1:AWGN:BWIDth:NOISe?
// Response: 7680000
SOURce1:AWGN:FREQuency:CENTer:OFFSet 1000000
// Shifts the noise signal by 1 MHz relative to the carrier frequency.
SOURce1:AWGN:DISP:MODE RFA
SOURce1:AWGN:POWer:NOISe -80
// SOURce1:POWer:LEVel:IMMediate:AMPlitude?
// Response: -80
SOURce1:AWGN:POWer:NOISe:TOTal?
Example: Generating a CW interferer signal
