697Operating Manual 1407.6062.32 ─ 08
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 [:SOURce<hw>]:SWEep[:
FREQuency]:STEP[:LINear] on page 697).
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 [:
SOURce<hw>]:SWEep[:FREQuency]:STEP:LOGarithmic
on page 698).
*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.
