I need to measure two signals - basic sine waves at nominally 30 Hz and 60 Hz. I need to know the actual frequency with a resolution of 0.05 Hz or better. I would also like to measure the Q of the signal(s), which are generated by mechanically resonat systems. The Q is pretty high in these systems, somewhere around 100.
This is a single channel requirement. I have looked at the ADC-42, which looks like it has the spec's to do the job. I downloaded the demo software and the interface looks promising. What I couldn't tell from the demo is:
1) Can I use the spectrum analyzer to measure 30 and 60 Hz with the required resolution?
2) Is there any "automated" way of determining the resonant frequency (short of picking it off the screen)?
3) Is there any "automated" way of determining the Q of a signal?
4) Is there an easy way to export a captured signal in terms that excel or another math package can get the raw data (ascci text?) to determine the Q?
Thanks for a good looking product that I'm hoping to try!
