Prerequisites for this command
●
Turn on XCORR optimization (
[SENSe:]SWEep:XOPTimize[:STATe]
on page 366).
Parameters:
<Threshold> <numeric value>
Default unit: dB
Example: //Define a threshold of 15 dB
SWE:XOPT:THR 15
Manual operation: See "Defining cross-correlation parameters" on page 113
[SENSe:]TIME:STARt <Tau>
This command defines the start time for the frequency stability measurements.
Effects of this command
●
The start time is coupled to the stop frequency offset of the measurement range of
the phase noise measurement (
[SENSe:]FREQuency:STOP
).
If you change the start time, the R&S FSPN adjusts the stop frequency offset
accordingly. For example, 1 MHz stop offset corresponds to 1 µs.
Parameters:
<Tau> <numeric value>
*RST:
1 ms
Default unit: s
Example: //Define start time for frequency stability measurement
TIME:STAR 1US
Manual operation: See "Defining the measurement range" on page 108
[SENSe:]TIME:STOP <Tau>
This command defines the stop time for the frequency stability measurements.
Effects of this command
●
The stop time is coupled to the start frequency offset of the measurement range of
the phase noise measurement (
[SENSe:]FREQuency:STARt
).
If you change the stop time, the R&S FSPN adjusts the start frequency offset
accordingly. For example, 1 mHz start offset corresponds to 1000 s.
Parameters:
<Tau> <numeric value>
*RST:
1 ms
Default unit: s
Example: //Define stop time for frequency stability measurement
TIME:STAR 1000S
Manual operation: See "Defining the measurement range" on page 108
