3.3 Instrument subsystem command
37
Reset status: Freq Start + (Freq Stop - Freq Start)/2
Key Entry:
【
Frequency
】 —>[CW]
[:SOURce]:FREQuency:MODE <Mode>
Function: This command sets the frequency mode of the signal generator.
Setting format: [:SOURce]:FREQuency:MODE FIXed|CW|SWEep|LIST
Query format: [:SOURce]:FREQuency:MODE?
Parameter:
<Mode> Discrete data, Current Sweep Type to be configured. The values are as follows:
FIXed|CW The setting of these two discrete parameters is the same in the signal
generator in meaning, that is, the controlled signal generator outputs
CW (spot frequency) signal, which will terminate the frequency sweep
signal currently output by the instrument.
For setting spot frequency, please refer to the commands
―
:FREQuency[:CW]
‖ and ―
:FREQuency[:FIXed]
‖.
SWEep This parameter sets current frequency mode as sweep mode. Sweep
mode in the software, whether step sweep or ramp sweep, is determined
by:
―
SWEep:GENeration
‖. The default is step sweep.
LIST Current Sweep Type is set to List mode. If the current list is empty, the
signal generator will prompt the list is empty. The signal generator can
start sweep only when there is at least one sweep point in the list.
Example: :FREQuency:MODE LIST Set the signal generator to List Sweep mode.
Reset status: CW
[:SOURce]:FREQuency:MULTiplier <FreqMult>
Function: This command sets Freq Mul for signal source. When set Freq Mul is greater than 1, a
multiplier indicator "*" is displayed in frequency display area. At this time, displayed
frequency value= RF output frequency value ×multiplier. However, the actual
frequency output is still the frequency with no multiplier added. When Freq Mul is set
to 1, the indicator disappears.
Setting format: [:SOURce]:FREQuency:MULTiplier <val>
Query format: [:SOURce]:FREQuency:MULTiplier?
Parameter:
<FreqMult> Freq Mul.
Range: 1[1
，
36].
Example: :FREQuency: MULTiplier 8 Freq Mul of the signal generator is 8.
Reset status: 1
Key Entry:
【
Frequency
】 —>[Basic Config]->[Freq Mul]
[:SOURce]:FREQuency:OFFSet <FreqOffs>
Function:
When Frequency Offset is not set to zero, an offset indicator ―*‖ is displayed in
frequency display area, and the display value becomes the frequency value plus offset.
