The starter of the thread, Don, asked a question and I tried to help and get a discussion going.
Then someone writes this in the third post of the thread;
//Unfortunately that note does not answer his nor my question. //
That is not "common courtesy" in my book.
Now are you Don? And if so why are you writing about yourself in third person? Makes things very confusing if that's the case.
It's a good thing to use a name or a moniker so people know in a forum who they talk to and respond to.
And as I mentioned earlier, I more or less did answer your (or Don's..)question by pointing to the info in my thread.
You see a forum is to help eachother, and since I have the same line of scope (3224) and also recently upgraded to Picoscope 6 and having problem with frequency measurements I am interested in what results you (or Don) get.
I can not get the results that picojohn got which can bee seen in the PS3224.doc in the other thread.
Now for the measurment, try this:
set spectrumrange at 4.883kHz
set spectrum bin/FFT size at 1024
this will give you aprox 5Hz resolution.
15-30 seconds should be fine for the sweep.
the sampling frequency is set automatically in PS6 to twice the frequency of your setting of spectrum range and 9,766kS/s should give you accurate results up to 4k.
Please also do me a favor.. try to measure a full 20-20k range with the settings 39.06kHz and 8192 bin size with a 30-60second sweep..
