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.
The actual frequency at the RF output does not change, but rather the value queried
with [:SOUR]:FREQ?, according to the formula:
f
FREQ
= f
RFout
* f
MULTiplier
+ f
OFFSet
Correlation: FREQ for FREQ:MODE SWE is linked to the sweep frequency.
Parameters:
<Fixed> float
Range: full frequency range
Increment: see the data sheet: RF characteristics > Resolution
of setting
*RST: 100 MHz
Example:
FREQ 500kHz
sets the frequency of RF output signal A to 500 kHz.
Manual operation: See "RF Freq" on page 138
[:SOURce<hw>]:FREQuency[:CW|FIXed]:RCL <Rcl>
Determines whether the RF frequency value is retained or taken from a loaded instru-
ment configuration, when you recall instrument settings with the command *RCL.
Parameters:
<Rcl> INCLude | EXCLude
INCLude
Takes the frequency value of the loaded settings.
EXCLude
Retains the current frequency when an instrument configuration
is loaded.
*RST: INCLude
Example:
FREQ:RCL INCL
takes the frequency from the loaded instrument configuration.
Manual operation: See "Exclude Frequency" on page 129
[:SOURce<hw>]:FREQuency:MANual <Manual>
Determines the frequency and triggers a sweep step manually in SWE:MODE MAN.
