RD JDS6600 25MHz 2-Channel DDS AW Function Signal Generator

Right you are.
I'll reel my neck back in.
trys:
Hold on a little minute.
(Neck emerges from under its shell)
I've taken two photos of the screen (see below). Is the "Function Counter" the thing you are after then?

Maybe? I don't have one to test. A universal counter should ideally have a settable threshold and the ability to compare two channels, but the latter isn't super vital, though the former makes it more usable. Having neither, but a predictable way of counting discrete steps is still nice.
It shouldn't be hard to test. If you run a low frequency signal generator and the count goes up and over the frequency, it looks like it's also doing counting.

Here we go, I've tested it for you.
I put the scope's probe 1Khz compensation calibration squarewave to the "Ext In" of the JDS6600 and tried both the "counter" and the "measure". One counts pulses over time (you can stop/pause, start and clear it), and the other measures the frequency.
(Shots below).

Nice. I don't think I've ever seen anyone demonstrating this before. Having a threshold value would be great, and a compare nice, but this certainly increases the appeal of the device.
