Regarding the cjds38-b, can rf output be modulated with a tone? i can't see from the manual how to do this.

No. Feed signal into your AM modulator.

Can a preset output signal be turned on and off using an external digital input?

You are asking if there is an external trigger input if I read your question correctly. No, there is no external trigger input to turn on a preset waveform. You can manually turn of either channel with a push button switch on each channel.

Hi, i have this device but i would like more power (higher vpp). do i need to buy a power amplifier?

Yes, you might get a lab amp, works well. At home I used a 3000W stereo amp, that worked well too.
