[:SOURce<hw>]:FREQuency:STARt <Start>
This command sets the start frequency for the sweep mode. STARt can be greater than
STOP.
This command is linked to the commands [SOUR]:FREQ:CENT and
[SOUR]:FREQ:SPAN, i.e. changing these values causes the STARt value to change,
and vice versa:
STARt = (CENTer - SPAN/2).
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:
300 kHz + OFFSet ... RF
max
+OFFSet
Parameters:
<Start> float
Range: 300kHz to RFmax
Increment: 0.01Hz
*RST: 100MHz
Example:
FREQ:STARt 1 MHz
sets the start frequency for the frequency sweep to 1 MHz.
FREQ:STOP 2 GHz
sets the stop frequency for the frequency sweep to 2 GHz.
Usage: SCPI confirmed
[:SOURce<hw>]:FREQuency:STOP <Stop>
This command sets the stop frequency for the sweep mode. STOP can be less than
STARt.
This command is linked to the commands [:SOUR]:FREQ:CENt and
[:SOUR]:FREQ:SPAN, i.e. changing these values causes the STARt value to change,
and vice versa:
STOP = (CENTer + SPAN/2)
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:
300 kHz + OFFSet ... RF
