Command Description R&S SMC100A
1411.4060.32 6.46 E-1
[SOURce:]FREQuency:MANual STARt ... STOP
In Sweep mode (:SOUR:FREQ:MODE SWE) the command sets the frequency for the next sweep
step in the Step sweep mode (SOUR:SWE:MODE MAN). Here only frequency values between the
settings [SOUR]:FREQ:STAR and ...:STOP are permitted. Each sweep step is triggered by a
s
eparate SOUR:FREQ:MAN command.
As with the Frequency value entered in the header, the Offset value is also taken into
consideration with this command. The specified value range is therefore only effective if Offset is
set to 0. The value range for other Offset values can be calculated using the following formula (see
also Chapter 4).
STARt + Offset ... STOP +Offset
Example:
SWE:MODE MAN
'sets the Step sweep mode.
FREQ:MAN 500MHz
'sets an RF frequency of 500 MHz for the next step in the Step sweep mode.
FREQ:MODE SWE
'sets the Frequency Sweep mode. An RF frequency of 500 MHz is output.
FREQ:MAN 550MHz
'triggers the next sweep step with an RF frequency of 550 MHz.

[SOURce:]FREQuency:MODE CW|FIXed | SWEep
The command sets the instrument operating mode and therefore also the commands used to set the
output frequency.
Parameters: CW|FIXed
The instrument operates in fixed-frequency mode. CW and FIXed are
synonyms. The output frequency is set with
:SOURce:FREQuency:CW|FIXed.
SWEep
The instrument operates in SWEep mode. The frequency is set using the
commands SOURce:FREQuency:STARt; STOP; CENTer; SPAN;
MANual.
Example:
FREQ:MODE SWE
'sets the SWEep mode. The settings under SOURce:FREQuency:STARt;
STOP; CENTer; SPAN; MANual become effective.
