Larry,
Thanks. I did a recalibration and it now is producing sensible answers. I'm still a bit confused by the UI, but that may be old FW or PEBKAC.
I did not see anything about shields when I looked through the files section, but I'll look again.
I'm quite excited by this as it is the RF version of the $20 LCR meter and the $10 DMM. I have an 8753B/84046A, VNWA and xaVNA so I didn't need this. But I remember all too well being a poor student trying to build a 40 M DC receiver and failing for lack of T&M gear. I had a VOM, DMM and 5 MHz recurrent sweep Heathkit IO-18 scope. Not exactly a recipe for success building RF band pass filters :-(
It will be very interesting to see what I find when I submit it to the tender mercies of my test bench ;-)
At this point my biggest concern is the limited flash of the MCU. I can think of a lot of features to add. But that may be better done in a PC program.
David Kirkby talked me into buying this. I'm really glad he did. I spent some time working on designing one, but abandoned the project when I realized there were a lot of other people doing the same thing. Edy555 has done a fantastic job.
#$%^&*!!! I was just tightening the short on CH0 with a Suhner torque wrench when both the ground pins on the SMA PCB connector broke off!!! Fortunately I have a bunch of replacements, but it does not give me much confidence in their quality :-(
sigh.....
