260 Operating Manual 1411.4060.32 ─ 04
Example: FREQ:CENT 400 MHz
sets the center frequency of the frequency sweep to 400 MHz.
FREQ:SPAN 200 MHz
sets a span of 200 MHz. This sets the sweep range to 300 MHz
to 500 MHz.
Usage: SCPI confirmed
[: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 = ( SPAN/2)
