317Operating Manual 1407.0806.32 ─ 13
Parameters:
<Shape> SAWTooth | TRIangle
SAWTooth
One sweep runs from start to stop frequency. Each subsequent
sweep starts at the start frequency, i.e. the shape of the sweep
sequence resembles a sawtooth.
TRIangle
One sweep runs from start to stop frequency and back, i.e. the
shape of the sweep resembles a triangle. Each subsequent sweep
starts at the start frequency.
*RST: SAWTooth
Example:
SOUR:LFO:SWE:SHAP TRI
selects the sweep cycle with alternating ascending and descend-
ing sweep directions.
Manual operation: See "Shape - LF Frequency Sweep" on page 192
[:SOURce]:LFOutput:SWEep[:FREQuency]:SPACing <Spacing>
The command selects linear or logarithmic sweep spacing.
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]:LFOutput:SWEep[:
FREQuency]:STEP[:LINear] on page 317).
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]:LFOutput:SWEep[:FREQuency]:STEP:
LOGarithmic on page 318).
*RST:
LINear
Example:
LFO:SWE:SPAC LIN
selects linear sweep spacing.
Manual operation: See "Spacing - LF Sweep" on page 192
[:SOURce]:LFOutput:SWEep[:FREQuency]:STEP[:LINear] <Linear>
The command sets the step width for the linear sweep.
This command is linked to the com-
mand :LFOutput:SWEep[:FREQuency]:POINts as follow.
