[:SOURce<hw>]:FREQuency:LOSCillator:MODE <Mode>
Parameters:
<Mode> INTernal | EXTernal | COUPled | ECOupled
INTernal
The signal of the internal local oscilltor is used. This mode corre-
sponds to a normal operation.
EXTernal
An external signal is used for path A.
Note: Selection of LO Coupling "External" mode, disables all
parameters in the "Frequency/Phase/Ref Osc" dialog of the
selected path.
*RST:
INTernal
Example: FREQ:LOSC:MODE EXT
sets the LO coupling mode to External.
Manual operation: See "Mode - LO Coupling" on page 214
[:SOURce<hw>]:FREQuency:LOSCillator:OUTPut:STATe <State>
Switches on/off the LO output.
Parameters:
<State> 0 | 1 | OFF | ON
*RST:
0
Example:
FREQ:LOSC:OUTP:STAT ON
switches on the LO output state.
Manual operation: See "Out State - LO Coupling" on page 214
[:SOURce<hw>]:FREQuency[:CW|FIXed] <Fixed>
Sets the frequency of the RF output signal.
In CW mode, see FREQ:MODE CW|FIXed , the instrument operates at a fixed fre-
quency.
In sweep mode FREQ:MODE SWE , the value applies to the sweep frequency and the
instrument processes the frequency settings in defined sweep steps.
You can enter either a numerical frequency value, of decrease or increase the current
frequency step by step with
FREQ UP and FREQ DOWN . The frequency is then
increased or decreased by the value
[:SOURce<hw>]:FREQuency:STEP[:
INCRement]
in FREQ:STEP:MODE USER .
Note:
A defined offset and the multiplier factor affect the sweep range and therefore all corre-
lated parameters. The set frequencies are only absolute values, if the offset = 0 and
the multiplication factor = 1. The multiplier multiplies the frequencies accordingly, and
the offset ≠ 0 shifts the frequencies corresponding to the set value.
