Remote Control Commands
SOURce:AWGN Subsystem
This command is available for modes Additive Noise and Noise Only (SOUR:AWGN:MODE
ADD|ONLY).
Parameters:
Example:
float
Range: 1.0E3 to 100.0E6
Increment: 0.1E3
*RST: 3.84E6
SOURce:AWGN:MODE ADD
SOURce:AWGN:BWIDth 10 MHz
sets a system bandwidth of 10 MHz.
Manual operation: See "System Bandwidth - AWGN" on page 123
[:SOURce]:AWGN:BWIDth:NOISe?
This command is available for modes In Additive Noise and Noise Only
(SOUR:AWGN:MODE ADD|ONLY) modes, queries the real noise bandwidth.
Return values:
Example:
Usage:
float
Range: 0 to 200.0E6
Increment: 0.1E3
*RST: 0
AWGN:BWID:NOIS?
queries the noise bandwidth.
Query only
Manual operation: See "Noise Bandwidth - AWGN" on page 124
[:SOURce]:AWGN:BWIDth:RATio
In Additive Noise and Noise Only (SOUR:AWGN:MODE ADD|ONLY) modes, sets the ratio
of minimum real noise bandwidth to system bandwidth.
The overall bandwidth is calculated as follow and may not exceed the total bandwidth
specified in the data sheet:
The value range of this parameter is automatically adjusted depending on the selected
instrument. The maximum ratio minimum noise bandwidth to system bandwidth is determinate
by the max sample clock of the selected instrument and is calculated so that the
overall bandwidth, i.e. "System BW" x "Minimum Noise"/"System BW Ratio" has to be
less or equal to the sampling rate of the selected instrument.
Parameters:
float
Range: 1 to Max
Increment: 0.1
*RST: 1
