is determined by sweep time.
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 →Open softkey 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.
