Operating Manual 1411.4060.32 ─ 04
Parameters:
<Multiplier>
float
Range:
1 to 10000
*RST:
1
Example:
FREQ:MULT 1
sets the multiplication factor to 1.
[:SOURce<hw>]:FREQuency:OFFSet
<Offset>
The command sets the frequency offset of a downstream instrument, e.g. a mixer. If a
frequency offset is entered, the frequency entered with
SOURce:FREQuency:...
no
longer corresponds to the RF output frequency. The following correlation applies:
SOURce:FREQuency:...
= RF output fre
SOURce:FREQuency:OFFSet
.
Entering an offset does not change the RF output frequency, but rather the query value
of
SOURce:FREQuency:...
.
Parameters:
<Offset>
float
Range:
-67GHz to 67GHz
Increment: 0.01Hz
*RST:
0Hz
Default unit: Hz
Example:
FREQ:OFFS 500kHz
sets the frequency offset to 500 kHz.
Usage:
SCPI confirmed
[:SOURce<hw>]:FREQuency:SPAN
<Span>
This command specifies the span for the sweep. This setting in combination with the
center frequency setting (
[SOUR]:FREQ:CENT
) defines the sweep range.
This command is linked to the commands
[SOUR]:FREQ:STAR
and
[:SOUR]:FREQ:STOP
, i.e. changing these values causes the
SPAN
value to change,
and vice versa:
SPAN
= (
STOP - STARt
)
Negative values for
SPAN
are permitted;
STARt
>
STOP
then applies.
Parameters:
<Span>
float
Range:
0 to RFmax
Increment: 0.01Hz
*RST:
400MHz
