2 evenings at least. Do you have some wishes in the format you need, a protocol as such?
Perfect!
For the format, as long as it is in an Excel like format it will be fine.
For the protocol, the only special thing I can think of is to do tests with and without 50 Ohms load, and at least Vpp for Sine, Square and Ramp waves (and maybe others that you might think interesting) on the 3 ranges + DC
For the rest I am sure you will have other ideas when you see special things during tests execution.
The idea would be that your protocol could be used as a basis for others so that we could have some statistical data.
I will also run your protocol on my 2 FGs. If others can also help and run your protocol, that would help also (cybermaus, DC1MC, DaveR, Kaku, ... any volonteer, depending on your free time, you help will be very much appreciated
