Parameters:
<Mode> AUTO | MANual | STEP
AUTO
Each trigger triggers exactly one complete sweep.
MANual
The trigger system is not active. Each frequency step of the sweep
is triggered individually, either by varying the "Current Fre-
quency" value using the rotary knob under manual control or by
means of a
:LFOutput:FREQ:MAN
command under remote con-
trol.
With manual control, the frequency increases or decreases
(depending on the direction of the rotary encoder) by the value
specified under
SOUR:LFO:SWE:FREQ:STEP:LIN
(linear spac-
ing) or
...:STEP:LOG
(logarithmic spacing).
With remote control, the frequency increases by the value speci-
fied under
LFO:SWE:FREQ:STEP:LIN|LOG
which each sent

STEP
Each trigger triggers one sweep step only. The frequency increa-
ses by the value entered under
[SOURce:]LFOutput:SWEep:STEP
.
*RST: AUTO
Example: LFO:SWE:MODE AUTO
selects Mode Auto.
[:SOURce]:LFOutput:SWEep[:FREQuency]:POINts <Points>
The command sets the number of steps in an LF sweep.
The command is linked to the command
:LFOutput:SWEep[:FREQuency]:STEP
as
follows:
●
for linear sweeps and
STARt < STOP
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.
