SOURce:FREQuency SME
1038.6002.02 3.66 E-13
[:SOURce]:FREQuency:MANual 5 kHz to 1.5 GHz (SME03E/03/06: 5 kHz to 2.2/3/6 GHz)
The command sets the frequency if SOURce:SWEep:MODE MANual and
SOURce:FREQuency:MODE SWEep are set. Only frequency values between the settings with
:SOURce:FREQuency:STARt and :SOURce:FREQuency:STOP are permitted. (As to specified
range, cf. FREQuency:CENTer) *RST value is 100 MHz
Example: :SOUR:FREQ:MAN 500MHz
[:SOURce]:FREQuency:MODE CW | FIXed | SWEep | LIST
The command specifies the operating mode and hence also specifies which commands check the
FREQuency subsystem. The following allocations are valid
CW |FIXed CW and FIXed are synonyms. The output frequency is specified by means of
:SOURce:FREQuency:CW | FIXed.
SWEep The instrument operates in the SWEep operating mode. The frequency is specified
by means of commands SOURce:FREQuency:STARt; STOP; CENTer; SPAN;
MANual.
LIST The instrument processes a list of frequency and level settings. The settings are
effected in the SOURce:LIST subsystem. Setting SOURce :FREQuency:MODE LIST
automatically sets command SOURce:POWer :MODE to LIST as well.
Example: :SOUR:FREQ:MODE LIST *RST value is CW.
[:SOURce]:FREQuency:OFFSet -50 to + 50 GHz
The command sets the frequency offset of an instrument which might be series-connected, e.g. a
mixer. (cf. Chapter 2, Section "Frequency Offset"). If a frequency offset is entered, the frequency
entered using SOURce:FREQuency: to does no longer correspond to the RF output frequency.
The following connection is true:
SOURce:FREQuency:to = RF output frequency + SOURce:FREQuency:OFFSet.
Entering an offset does not alter the RF output frequency but the query value of
SOURce:FREQuency:..
Example: :SOUR:FREQ:OFFS 100MHz *RST value is 0
[:SOURce]:FREQuency:SPAN 0 to 1.5 GHz (SME03E/03/06: 5 kHz to 2.2/3/6 GHz)
This command indicates the frequency range for the sweep. This parameter is coupled to the start
and stop frequency. Negative values for SPAN are permitted, then STARt > STOP is true. There
is the following connection:
STARt = CENTer – SPAN/2
STOP = CENTer + SPAN/2 *RST value is (STOP - STARt)
Example: :SOUR:FREQ:SPAN 1GHz
[:SOURce]:FREQuency:STARt 5 kHz to 1.5 GHz (SME03E/03/06: 5 kHz to 2.2/3/6 GHz)
This command indicates the starting value of the frequency for the sweep operation. Parameters
STARt, STOP, SPAN and CENTer are coupled to each other. STARt may be larger than STOP.
(As to specified range, cf. FREQuency:CENTer). *RST value is 100MHz
Example: :SOUR:FREQ:STAR 1MHz
