Hello,
Statistics measurements for a 7.5kHz triangular wave (approximately +10max /-10min) is taking a little over a minute. I have set N=300, On Single:1 and 100kHz filter to On. Why is it taking so long? Isn't it only taking 300 samples, which should only take 0.04seconds ( = (1/7.5K)*300 seconds)? The filter maybe having an effect, but I wouldn't think it would cause the statistic measurement to take 1500 times longer.
Also, I read the 53131A user's manual and I am still confused about what On Single: 1 and On Single: N means.
Isn't the On Single: 1 setting also using N=300 samples?

I tried to do same thing on my 53132A, with GATE TIME AUTO, I had 10sec/reading with STAT ON and displayed MEAN, calculated with 300 samples. But with GPIB, when I cut extra processing of counter, I had around 1.1sec/reading for an input frequency of 7.5kHz and 300 samples.
I think that "ON SINGLE 1" is for a single shot statistic, maybe not avalaible depend of firmware revision (programming guide pdf page 16/330).
I don't know if this information may help you.
