nanoVNA vs SVA1015X VNA (Need entry level VNA)

<< < (5/14) > >>

The sva1015x works well from 10MHz to 1.5 GHz.  If i am working in that range it is the one I use.  I especially like the log frequency sweep feature and slightly greater dynamic range.  The interface is much nicer on the Siglent.  It is also faster.

However the nanovna-f works far better at lower frequencies.  The price is much better too.

I've watched some of your youtube videos on the  sva1015x Chris, some great information. My one concern with the sva1015x is the fixed 0dbm output power for the VNA. Is this really something to be concerned about? I assume I can just add an attenuator to the input of the DUT? Just a bit annoying I guess when you want to measure the 1db compression point for an amplifier.



LibreVNA also looks like a neat product

The cost of good step attenuators, bias-Ts, blocks, cables, adapters .....  are all something to consider.   

I did see a post about an improved version of the Lite being available now.  I have no idea how well it actually performs but may be worth looking into.

Both TG power level and Port 1 Stimulus level are user adjustable from -20 to 0dB.
This info is in the datasheet.

Why not try that one first? From what I've read so far in this thread and other information, it seems to be the best option in your budget range.

Cost is about $600.  Another member had posted about the software not being stable and hanging.  I assume you own one or you would not be recommending it.  Are you seeing similar problems with yours hanging and could maybe provide some additional insight?
