Sense
The external reference is used if a valid signal is sensed at the Ext Ref input. Otherwise the internal
reference is used.
[:SENSe]:ROSCillator:SOURce:TYPE
INTernal|EXTernal|SENSe
[:SENSe]:ROSCillator:SOURce:TYPE?
This is unaffected by a Preset but is set to SENSe on a "Restore Input/Output
Defaults" or "Restore System Defaults->All".
Saved in instrument state.
STATus:QUEStionable:FREQuency bit 2 set if unlocked.
Prior to A.02.00
[:SENSe]:ROSCillator:SOURce?
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
SENSe
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.
Prior to A.02.00
[:SENSe]:ROSCillator:SOURce INTernal|EXTernal
([:SENSe]:ROSCillator:SOURce:TYPE INTernal|EXTernal and directly sets
the routing to either internal or external.)
