[:SOURce<hw>]:FREQuency:LOSCillator:INPut:FREQuency?
Queries the required external reference frequency.
Return values:
<Frequency> float
Range: 100E3 to 20E9
Increment: 0.01
*RST: 0
Example: See Example "Set up of LO coupling and LO level adjustment
with three Rohde & Schwarz signal generators" on page 1038.
Usage: Query only
Manual operation: See "Mandatory LO IN Frequency" on page 452
[:SOURce<hw>]:FREQuency:LOSCillator:MODE <Mode>
Selects the mode of the local oscillator coupling.

Description
INTernal A&B Internal / Internal (one
path instrument)
Uses the internal oscillator signal in both
paths.
EXTernal A External & B Internal (one
path instrument)
Uses an external signal in path A. B uses its
internal signal.
COUPled A Internal & A->B Coupled Assigns the internal oscillator signal of path
A also to path B.
ECOupled A External & A->B Coupled Assigns an externally supplied signal to both
paths.
BOFF A Internal & B RF Off Uses the internal local oscillator signal of
path A, if the selected frequency exceeds
the maximum frequency of path B.
EBOFf A External & B RF Off Uses the LO IN signal for path A, if the
selected RF frequency exceeds the maxi-
mum frequency of path B.
AOFF A RF Off & B External Uses the LO IN signal for path B, if the
selected RF frequency exceeds the maxi-
mum frequency of path A.
Parameters:
<Mode> INTernal | EXTernal | COUPled | ECOupled | BOFF | AOFF
