I am preparing for portable operations once the weather gets warmer. I want to take along a nanovna to troubleshoot issues on the field. One important requirement is the scrolling and input control has to be buttons, not the thumbwheel switch so that left me with two options, the nanovna-F version 3.1 form Deepelec.com and the nanovna-SAA-2N which I purchased form R&L Electronics. Both are in metal cases which is an asset for filed work. I use BNC connectors so I Install adapters on each unit and use a BNC calibration kit.
I can use the command set or a computer program to configure the nanovna but I do not want to use a laptop or smartphone in the field, just a standalone unit.
Some other requirements and my observations are as follows:
- Frequency Range 1 to 30 Mhz in 100kHz steps (301 segments)
nanovna-F : 101 segments - have to use 3 RECALL settings for resolution
nanovna-SAA-2N : 201 segments - have to use 2 RECALL settings for resolution
- TDR functionality : both units support function via TRANSFORM settings
- Save and examine results
nanovna-F : STORAGE S1P and S2P
nanovna-SAA-2N : no storage
Are there any other models which have button controls, at lease 301 segments and save measurement to storage?
Thanks,
Mike N2MS
