Frequency Display

Post by QB » Thu Apr 20, 2006 5:56 pm

This has probably been answered before but here goes....I find that when I use the METER set to frequency that at some point, it starts to display 2X the correct frequency. The correct frequency is being displayed on the graph but on the meter it is 2x the amount. It seems to happen at frequencies above 1.5 kHz. Is it a limitation of the sampling rate? If anyone could shed light on the problem, I would be grateful.

Thanks

Sarah

Hi

I have not heard of this before. Which version of the software are you using? What hardware are you using? How long do you have to wait?

I can try to recreate this here then.

Best Regards

wait time

oops...forgot to say there is no wait time. The oscilloscope screen gives the correct frequency but above a certain frequency the frequency display starts giving the 2X value.
