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 lin-
ear sweep is entered in Hz (see [:SOURce<hw>]:LFOutput:
SWEep[:FREQuency]:STEP[:LINear] on page 356).
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>]:LFOutput:SWEep[:FREQuency]:STEP:
LOGarithmic on page 357).
*RST:
LINear
Example:
LFO:SWE:SPAC LIN
selects linear sweep spacing.
Manual operation: See "Spacing" on page 224
[:SOURce<hw>]:LFOutput:SWEep[:FREQuency]:STEP[:LINear] <Linear>
Sets the step size for linear LF frequency sweep steps.
This parameter correlates with the number of steps [:SOURce<hw>]:LFOutput:
SWEep[:FREQuency]:POINts within the sweep range as follows:
f
STARt
< f
STOP
freq_points = ((f
STARt
- f
STOP
) / step_lin) + 1
If you change the step size, the number of steps changes accordingly. The sweep
range remains the same.
Parameters:
<Linear> float
Range: full frequency range
Increment: see the data sheet: Modulation sources > Resolu-
tion of frequency setting
*RST: 1000
Example:
LFO:FREQ:STAR
sets the start frequency to 2 kHz.
LFO:FREQ:STOP
sets the stop frequency to 20 kHz.
LFO:SWE:SPAC LIN
sets linear sweep spacing.
LFO:SWE:STEP 2 kHz
sets the sweep step width to 2 kHz. The number of sweep steps
for linear sweep spacing (POINts) is automatically set to 11.
Manual operation: See "Step Lin/Log - LF Sweep" on page 225
