Remote Control Commands<br />

SOURce:AWGN Subsystem<br />

Example:<br />

Usage:<br />

AWGN:FREQ:RES?<br />

queries the actual frequency of the interfering sine<br />

Query only<br />

<strong>Manual</strong> operation: See "Resulting CW Frequency - AWGN" on page 124<br />

[:SOURce]:AWGN:FREQuency:TARGet <br />

Sets the desired frequency of the sine in AWGN:MODE CW mode.<br />

The range of this parameter is limited to ± (Symbol Rate + Sample Rate)/4<br />

Parameters:<br />

<br />

Example:<br />

float<br />

Range: -40E6 to 40E6<br />

Increment: 0.01<br />

*RST: 0<br />

AWGN:FREQ:TARG 2kHz<br />

sets a frequency of 2 kHz for the interfering sine.<br />

<strong>Manual</strong> operation: See "Target CW Frequency - AWGN" on page 124<br />

[:SOURce]:AWGN:MODE <br />

Selects the mode for generating the interfering signal.<br />

Parameters:<br />

<br />

Example:<br />

ONLY | ADD | CW<br />

ADD<br />

The AWGN noise signal is added to the baseband signal.<br />

ONLY<br />

The pure AWGN noise signal is modulated to the carrier. The connection<br />

to the baseband is interrupted.<br />

CW<br />

The sine interfering signal is added to the baseband signal.<br />

*RST:<br />

ADD<br />

SOURce:AWGN:MODE ONLY<br />

SOURce:AWGN:STATe ON<br />

selects the generation of a pure noise and activates it<br />

<strong>Manual</strong> operation: See "Mode - AWGN" on page 122<br />

[:SOURce]:AWGN:POWer:CARRier <br />

available for Additive Noise and CW Interferer (SOUR:AWGN:MODE ADD|CW) modes<br />
