Modulation Function
Press the MOD button on the front panel to enable the modulation function. The
FY6800 can output the modulating waveform from the CH1 channel. This function uses
the waveform signal of CH1 as the carrier wave, the waveform signal of CH2, the
external signal or the manual pulse signal as the modulation wave, and performs signal
modulation. It can realize FSK, ASK, PSK digital modulation, trigger pulse train output,
and AM, FM, PM analog signal modulation function. The modulation signal is input by
the Trig/FSK/ASK/PSK IN at the end of the signal generator.
(Note: The signal generator will execute the current modulation function immediately
after entering the modulation interface)
Modulation mode
Press the "Mode" key under the modulation function to switch the modulation mode.
These modes include
①
FSK (frequency keying).
②
ASK (amplitude keying).
③
PSK (phase keying).
④
trigger (controllable burst output).
⑤
AM (Amplitude Modulation).
⑥
FM (FM).
⑦
PM (phasing).
Each time the "Mode" button is pressed, the function will switch down once.
