OUTPut:POLarity { NORMal | INVerted }
OUTPut:POLarity?
Invert the waveform relative to the offset voltage. In the normal mode
(default), the waveform goes positive during the first part of the cycle.
In the inverted mode, the waveform goes negative during the first part of
the cycle. The
:POL?
query returns “NORM” or “INV”.
• As shown in the examples below, the waveform is inverted relative to
the offset voltage. Any offset voltage present will remain unchanged
when the waveform is inverted.
• When a waveform is inverted, the Sync signal associated with the
waveform is not inverted.
OUTPut:SYNC { OFF | ON }
OUTPut:SYNC?
Disable or enable the front-panel Sync connector. At lower amplitudes,
you can reduce output distortion by disabling the Sync signal. The default
setting is “ON”. The
:SYNC?
query returns “0” (OFF) or “1” (ON).
• For more details on the Sync signal for each waveform function,
see “Sync Output Signal” on page 66.
• When the Sync signal is disabled, the output level on the Sync
connector is a logic “low” level.
• When a waveform is inverted (
OUTP:POL
command), the Sync signal
associated with the waveform is not inverted.
• The
OUTP:SYNC
command is overridden by the setting of the
MARK
command used with the sweep mode (see page 210). Therefore,
when the marker frequency is enabled (and the sweep mode is also
enabled), the
OUTP:SYNC
command is ignored.
