I've just about given up trying to find the answer for myself, so hopefully someone else can put me right. What is the maximum possible frequency that Picolog can measure when using 'real time continuous' mode, 1 second sample intervals, and an ADC200/50? What ever I try I cannot get it to sensibly measure more than about 7kHz: I'd like just a bit more, and in any case I'm only interested in audio frequencies, which surely must be within the device's 25MHz capability?
I have tried:
- looking in both the help files and the pdf user guide,
- searching this forum
- and much experimentation, by altering the 'scan time' on the 'edit measurement' pop-up, which suggests that indeed considerably higher frequencies should be possible: all it does is go beserk (apparently due to aliasing effects) at frequencies greater than 7k.
Am I missing a trick somewhere?
I downloaded the latest Picolog version 5.12.0, but still no joy, and the user guide I've got is plw044.pdf, dated 21/6/04 (and this doesn't seem any different from what's in the help file anyway).
