Trigger Output; Comprehensive Example - UNI-T UTG1000 Series User Manual

2) When external trigger is selected, waveform generator will trigger through modulation interface hardware.
3) When manual trigger is selected, backlight of Trigger button will flash, press Trigger button for once, sweep
will be output.

4.2.6 Trigger Output

When trigger source is internal or manual trigger, trigger signal (square wave) can be output through external
modulation interface (Input/CNT probe). The default of trigger output option is "Close". If need to change, press
Parameter→Trigger Output →Opensoftkey in turn.
In internal trigger, signal generator output a square of 50% duty cycle through external modulation interface

(Input/CNT probe) at the beginning of sweep.
In manual trigger, signal generator output a pulse that has pulse width more than 1us through external

modulation interface (Input/CNT probe) at the beginning of sweep.
In external trigger, trigger output is output through modulation interface (Input/CNT probe), but trigger

output options in parameter list will be hid.

4.2.7 Comprehensive Example

In sweep mode, set a sine wave signal with 1Vpp amplitude and 50% duty cycle as sweep signal, and sweep way is
linear sweep, set the initial frequency of sweep to 1kHz and terminal frequency to 50kHz and sweep time to 2ms.
Use rising edge trigger of internal source to to output sweep wave. Specific steps are seen as following:
1) Enable Sweep Function
Press Menu→Sweep→Type→Linear in turn to start the Sweep function.
