Hi all,
I am working on a project but I run into a problem: I generated a linear FM waveform in the waveform generator (agilent 33220a) and Im trying to look at it using the oscilloscope (dso-x 3024a). First, it looks like a chirp, but when I press the stop button from the oscilloscope is looks like a constant sinusoid (but I need it to look like a chirp when stopped to collect data!) I read that I need to trigger it, I am not familiar with triggering but I attached the internal trigger from the waveform generator to the external trigger of the oscilloscope and now it looks like just a constant sinusoid!
Any idea what should I do to make it look like a chirp?
thank you so much!
 

Unsuitable (too slow) frequency ramp or oscilloscope time base too fast? Hard to know without the actual parameters.

Agilent DSOs have a pulse width trigger, so you can trigger at a specific frequency if you want to. Probably not required in the present case, but you can learn something for real difficult measurement problems
