Hi guys, this one has me stumped. I want to generate a shaped tone burst.
A sine wave signal AM modulated, and then gated so that I get a series of say 5 sinewaves of the carrier, each of those bursts am modulated, separated by the gate zero level.
I have a two channel Siglent function generator, and I can generate the modulated/shaped tone burst, OR the gated tone burst (which actually is a sine wave modulated by a square wave).
But I can't seem to combine it.
I tried to use the gated sine wave as external input and modulate it with a sine wave but that doesn't seem te work.
Attached is what I am after. Hopefully someone has an idea how to.
