654Operating Manual 1407.6062.32 ─ 08
Parameters:
<Spacing> LINear | LOGarithmic
*RST: LINear
Example:
LFO:SWE:SPAC LIN
selects linear sweep spacing.
[: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.
●
for STARt < STOP:
POINts = (((STOP-STARt) / STEP:LIN) + 1
If STEP:LIN changes, the value of POINTs is adjusted. The STARt and STOP value is
retained.
Parameters:
<Linear> float
Range: 0 to STOP-STARt
Increment: 0.1 Hz
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.
[:SOURce]:LFOutput:SWEep[:FREQuency]:STEP:LOGarithmic <Logarithmic>
The command specifies the step width factor for logarithmic sweeps. The next frequency
value of a sweep is calculated (for STARt < STOP) using the following formula:
New frequency = Old frequency + STEP:LOG x Old frequency
STEP:LOG therefore gives the fraction of the old frequency. The frequency is increased
by this fraction for the next sweep step. Usually STEP:LOG is given in percent, whereby
the suffix PCT must always be used.
The command is linked to the command :LFOutput:SWEep[:FREQuency]:POINts
as follows:
●
for logarithmic sweeps and STARt < STOP:
POINts = ((log STOP - log STARt) / log STEP:LOG) + 1
If STEP:LOG changes, the value of POINTs is adjusted. The STARt and STOP value is
retained.
