3206 scope and FFT trigering sequence

Post by Pavlik » Tue Aug 30, 2005 8:44 am

I am not sure is it a hardware or software issue. Any way, I have to ask.
I am trying to see a discharge impulses using 3206. For the purpose, in the software I open two windows, scope and spectrum.

The scope is set to: 200ns/div, x1, +-200mV, AC, off,off,AC, off.
The spectrum is set to: 100 MHz, x1, Auto, AC, off, AC, x1.
The trigger is set to: Repeat, Ch.A, Rising, 70mV, -20%.

For every single impulse, I have response only in one of the windows. Using simple words, first coming impulse was displayed on the Scope window, nothing happens on Spectrum window. Second impulse, Spectrum window show me the spectrum, no any change on Scope window.

I this case I am not sure what is the relation between Scope and Spectrum windows.

I want to capture one impulse in Scope window, and in the same time to see the spectrum of the SAME impulse in the same time in Spectrum window.

Thank you for your post.

Yes this does appear to be the case. I will pass details of this on to our software team as I am not sure what is causing it.

Best Regards
