6 RLC Swept SA Measurement Front-Panel & SCPI Reference
Input/Output
If an external frequency reference is being used, you must enter the frequency of the external
reference if it is not exactly 10 MHz. The External Ref Freq key is provided for this purpose.
Key Path Input/Output
Remote Command [:SENSe]:ROSCillator:SOURce:TYPE INTernal|EXTernal|SENSe
[:SENSe]:ROSCillator:SOURce:TYPE?
Preset This is unaffected by a Preset but is set to SENSe on a "Restore Input/Output Defaults" or
"Restore System Defaults->All".
State Saved Saved in instrument state.
Status Bits/OPC
dependencies STATus:QUEStionable:FREQuency bit 2 set if unlocked.
Backwards Compatibility
Notes Freq Ref In was not saved in state in the legacy instruments. It is a part of state in the X-Series.
Initial S/W Revision Prior to A.02.00
Remote Command [:SENSe]:ROSCillator:SOURce?
Notes The query [SENSe]:ROSCillator:SOURce? returns the current switch setting. This means:
1. If it was set to SENSe but there is no external reference so the instrument is actually using
the internal reference, then this query returns INTernal and not SENSe.
2. If it was set to SENSe and there is an external reference present, the query returns EXTernal
and not SENSe.
3. If it was set to EXTernal, then the query returns "EXTernal"
4. If it was set to INTernal, then the query returns “INTernal”
Preset SENSe
Backwards Compatibility
Notes The query [:SENSe]:ROSCillator:SOURce? was a query-only command in ESA which always
returned whichever reference the instrument was using. The instrument automatically switched
to the ext ref if it was present.
In PSA (which had no sensing) the command [:SENSe]:ROSCillator:SOURce set the reference
(INT or EXT), so again its query returned the actual routing.
Thus the query form of this command is 100% backwards compatible with both instruments.
