I have 2 function generators with me and each is outputting its own signal. The first one is a 100kHz square signal and the second one is a 10MHz sine signal. What I want to do is use the first signal as a gate signal to gate the second signal.

What should happen is that when the square signal goes up, the sine signal is then produced as a burst for x-amount of periods and then the sine signal will stop when the square signal goes down.

How can I go about accomplishing this? Thank you!

PS: I am using the SIGLENT SDG5162

  • \$\begingroup\$ What happens if you set the 100kHz square to CMOS level and connect it to the gate input of the 10MHz sine signal generator? \$\endgroup\$

  • \$\begingroup\$ I don't think I have that function to set it to that level :/ I'm not even getting an external signal from the first function generator right now \$\endgroup\$ Jul 23 '18 at 8:16
  • \$\begingroup\$ CMOS means your signal goes from low(0V) to high(5V), and what do you mean you don't even get an external signal from the first generator? \$\endgroup\$

The function generator offers an external input for gating function. Use the 100kHz square wave signal in CMOS TTL level(0V-5V) to gate the second function generator generating the 10MHz sine signal.
