Operating Manual 1411.4060.32 ─ 04
Parameters:
<Spacing>
LINear | LOGarithmic
LINear
With the linear sweep, the step width is a fixed frequency value
which is added to the current frequency. The step width for linear
sweep is entered in Hz (see
LOGarithmic
With the logarithmic sweep, the step width is a constant fraction
of the current frequency. This fraction is added to the current fre-
quency. The logarithmic step width is entered in % (see
on page 295).
*RST:
LIN
Example:
SWE:SPAC LIN
selects linear sweep spacing for a frequency sweep at the RF out-
put.
[:SOURce<hw>]:SWEep[:FREQuency]:STEP[:LINear]
<Linear>
The command sets the step width for linear sweeps.
This command is linked to the command
:SWEep[:FREQuency]:POINts
as follows:
POINts = (SPAN / STEP:LIN) + 1
If
STEP:LIN
changes, the value of
POINTs
is adjusted. The
STARt
and
STOP
value is
retained.
The keywords
[:FREQuency]
and
[:LINear]
can be omitted (see example). The
command is then SCPI-compliant.
Parameters:
<Linear>
float
Range:
0.001 Hz to (STOP - STARt)
Increment: 0.001 Hz
*RST:
1 MHz
Default unit: MHz
Example:
FREQ:STAR 1GHz
sets the start frequency to 1 GHz.
FREQ:STOP 5GHz
sets the stop frequency to 5 GHz.
SWE:SPAC LIN
sets linear sweep spacing.
SWE:STEP 2 MHz
sets the step width for linear sweep spacing to 2 MHz (RF sweep)
at the RF output. The number of sweep steps for linear sweep
spacing (
POINts
) is automatically set to 2001.
