[SENSe:]ROSCillator:LBWidth <Bandwidth>
Defines the loop bandwidth, that is, the speed of internal synchronization with the refer-
ence frequency. The setting requires a compromise between performance and increas-
ing phase noise.
For a variable external reference frequency with a narrow tuning range (+/- 0.5 ppm),
the loop bandwidth is fixed to 0.1 Hz and cannot be changed.
Parameters:
<Bandwidth> 0.1 Hz | 1 Hz | 3 Hz | 10 Hz | 30 Hz | 100 Hz | 300 Hz
The possible values depend on the reference source and tuning
range (see Table 12-2).
Default unit: Hz
Example:
ROSC:LBW 3
Manual operation: See "Loop Bandwidth" on page 616
[SENSe:]ROSCillator:O100 <State>
[SENSe:]ROSCillator:O640 <State>
This command turns the output of a reference signal on the corresponding connector
("Ref Output") on and off.
[SENSe:]ROSCillator:O640: Provides a 640 MHz reference signal on correspond-
ing connector.
Parameters:
<State> ON | OFF | 1 | 0
OFF | 0
Switches the reference off.
