[: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 ... RFmax + OFFSet
Correlation: STOP = (CENTer + SPAN/2)

Default unit:
FREQ:STOP 2 GHz
sets the stop frequency for the frequency sweep to 2 GHz.
FREQ:STAR 1 MHz
sets the start frequency for the frequency sweep to 1 MHz.

SCPI conformUsage:
[:SOURce<hw>]:FREQuency:STEP[:INCRement] <Increment>
The command sets the step width for the frequency setting if the frequency values
UP/DOWN are used and variation mode SOUR:FREQ:STEP:MODE USER is selected. The
command is linked to Variation Step for manual control, i.e. the command also sets the
step width of the rotary knob for Variation Active on.
In the case of two-path instruments, the step width can be set separately for each path.
