Hi all,
My Xprotolab Plain arrived today and I have the XScope software running on Linux Mint 18.1 flawlessly. I am wondering how one reads the frequency off the FFT plot? The manual mentions that FFT is the only way to do a frequency read on the analog inputs, so, how do you get the numbers?
?
Thanks!

For anyone who is wondering about this, here is what I have figured out:
The FFT frequency span AND the AWG sweep function ranges are both set by the current timescale of the oscilloscope. I made the following chart during testing:

If you look at the chart in a monospace font, it looks ok
