This command queries the state of Low Phase Noise function with the
current measurement conditions.

Parameter
status
Low Phase Noise function On/Off status
1
Uses Low Phase Noise function.
0
Do not use Low Phase Noise function.
Detail
This function is available when MS2830A-062/066 or MS2840A-066/166
is installed.
The phase noise characteristics can be improved using the Low Phase
Noise Function when the Low Phase Noise switch is On, the frequency
range is –20 MHz≤f≤3.7 GHz (–20 MHz≤f<3.5 GHz when Frequency
Band Mode is Spurious) and the Span Frequency is less than 1 MHz.
However, if a signal outside the DUT frequency range is input while
using the Low Phase Noise Function, it may be possible to measure
spurious noise generated within the unit.
Refer to the
MS2830A/MS2840A Signal Analyzer Operation Manual
(Spectrum Analyzer Function Operation)
for details about spurious noise
generation and appropriate conditions for using the Low Phase Noise
Function.
Example of Use
To query the state of Low Phase Noise function with the current
measurement conditions.
