Channel Setup
12.2
Trigger Output Setup
In Burst or Sweep mode, when the trigger source is set to "Internal" or "Manual", the
generator outputs a TTL-compatible signal with the specified edge via the rear-panel
[AUX IN/OUT] connector.
NOTE
•
In internal trigger, the generator outputs a square waveform with 50% duty cycle via the
rear-panel [AUX IN/OUT] connector at the beginning of the burst/sweep.
•
In manual trigger, the generator outputs a pulse with greater than 4 μs pulse width via
the [AUX IN/OUT] connector at the beginning of the burst/sweep.
•
In external trigger, the [AUX IN/OUT] connector is used as the input terminal of external
trigger signals and does not support trigger output.
Click or tap the Trig Out drop-down button to specify the edge of the trigger output
signal. The default setting is "Off".
•
Off: disables the trigger output signal.
•
Leading: outputs the trigger signal of the leading edge.
•
Trailing: outputs the trigger signal of the trailing edge.

Output Polarity
You can use either the normal mode or Invert mode to output signals. Click or tap the
Invert on/off switch to enable or disable the invert function. The default is "Off".
The waveform is inverted relative to the offset voltage. As shown in the figure below,
relative to the offset voltage, the waveform is inverted.
TIP
•
Setting the waveform invert does not invert the sync signals related to the waveform. To
invert the sync signal, refer to
"negative".
•
The offset voltage remains unchanged when the waveform is inverted.
