Hi all,
I have made measurements with my new device.
My device is a NanoVNA-F Vector Network Analyzer.
This is nice a small compact device, but not too small to use. It has a
decent screen size that is very readable and usable for the touch screen
functions by your finger. It also has a very decent capacity battery.
very cool device. One thing to be aware of when working with a TC and
one of these is that they have *no* front end protection. So static can
easily destroy them. On the small ones - the Port 1 goes into a 14 dB
resistive pad, which will help, but on the Port 0 (the one likely to be
of interest to a TC doing tuning) has just a 50 ohm bridge and some
voltage dividers.
the NanoVNA2, as I recall, might be more vulnerable because it has some
RF switches that are directly connected to the ports.
