POINts = ((STOP-STARt) / STEP:LIN) + 1
●
for logarithmic sweeps and STARt < STOP
POINts = ((log STOP - log STARt) / log STEP:LOG) + 1
If POINTs changes, the value of STEP is adjusted. The STARt and STOP value is retained.
Two separate POINts values are used for linear or logarithmic sweep spacing
(LFOutput:SWEep[:FREQuency]:SPACing LIN | LOG). The command is always
effective for the currently set sweep spacing.
Parameters:
<Points> float
Increment: 1
*RST: 100
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:POIN 11
sets 11 sweep steps for linear sweep spacing. The sweep step
width (STEP) is automatically set to 2 kHz.
[:SOURce]:LFOutput:SWEep[:FREQuency]:SHAPe <Shape>
The command sets the cycle mode for a sweep sequence (shape).
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.
[:SOURce]:LFOutput:SWEep[:FREQuency]:SPACing <Spacing>
The command selects linear or logarithmic sweep spacing.
