The Trigger Input on Windfreak Technologies RF signal generators allow the end-user to do multiple things:
- Trigger full RF sweeps
- Trigger single steps in an RF sweep
- Externally pulse modulate
- Externally put the device to sleep for full RF quieting and power savings
- Externally FM modulate
- Externally AM modulate
With some devices like the SynthUSB3 and SynthHD Mini, trigger comes in through the USB port. Windfreak supplies USB breakout boards that give easy access to trigger and other signals.
