Reference Oscillator Commands
The [SOURce]:ROSCillator commands provides more advanced time keeping
functions for the 5071A. These functions increase the flexibility of the 5071A by
providing a means of:
setting reference oscillator tuning voltage,
setting fractional frequency offsets,
programming output-port frequency, and
checking the monitor voltage for the ovenized oscillator.
ROSCillator:CONTrol <numeric_value>
This command controls the reference oscillator tuning voltage as a signed
fraction of full scale with the supplied parameter.
The 5071A must be in REMote mode to execute this command.
This command requires that PTIMe:STANdby is ON for successful completion;
otherwise, the command is ignored.
Precision of control = one part in 32767.
Range = ± 3.3 x 10
-7
in frequency.
ROSCillator:CONTrol? [MIN|MAX]
This query returns the reference oscillator frequency control setpoint as a signed
fraction of full scale or minimum-maximum acceptable range limits.
Response format = <NR3>, precision = 1 x 10
-4
or better.
ROSCillator:STEer <numeric_value>
This command introduces a fractional frequency offset in the output frequencies
with the supplied parameter.
The 5071A must be in REMote mode to execute this command.
The instrument maintains servo lock to the Cesium resonance.
Parameter range = -1 x 10
-9
to +1.0 x 10
-9
.
The function of this command is set to 0.0 by *RST.
