744 Operating Manual 1403.7458.32 ─ 14
Example: SOUR:LFO:SWE:SHAP TRI
selects the sweep cycle with alternating ascending and
descending sweep directions.
Manual operation: See "Shape" on page 258
[:SOURce<hw>]:LFOutput:SWEep[:FREQuency]:SPACing <Spacing>
Selects the mode for the calculation of the frequency sweep intervals.The frequency
increases or decreases by this value at each step.
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 744).
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 745).
*RST: LINear
Example: LFO:SWE:SPAC LIN
selects linear sweep spacing.
Manual operation: See "Spacing" on page 258
[: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
