I'm now at the point in my project where I must consider the data collection and display aspects. As far as I can see your Picolog 1012 will be fine as my (hobby) budget has to be considered!
I'm resonating LCR circuits with a sweep gen over (approx) 20Hz to 40kHz: the sweep frequency is expected to be between 0.1Hz and 1Hz.
Central to the data issue is a frequency response plot. I also will need to log and display various other parameters along with it, that could either be sinewaves where just amplitude is important, or DC. (I could RMS to DC convert those AC signals if nesc).
AC signals will move about 0V so would the P'1012 be OK if I capacitor couple the AC waveforms as long as they remain within the 2.5V fsd of the input chan?
Will the software allow me to use a log scale on the X and / or Y axis?
By "display", above, I mean to print a copy of the resulting graph. I am less bothered about viewing the graphs on the laptop screen as they happen, though it would be nice!
