I would recommend keeping the firmware version that it comes with until you
have used it for awhile and become very familiar with its operation. Newer
versions of firmware have added many useful features, but all versions have
been very solid in basic operation, including your intended use case of
analyzing antenna vswr performance. So there is no real need to upgrade
until you find a feature you want but don't already have.
And no need to worry about chipset performance if the correct firmware is
loaded.

Hi,
I am awaiting delivery of my first nanovna H4. It is going to be used to
examine various types of mobile VHF aerial sytems swr performance.
I have never used one and I do NOT know which version or chipset it is
using until it is delivered.
But while I am waiting for it to arrive I would like to try and understand
the following -
1. Which is the "best" stable version of code that I am likely to require.
2. I read there may be "suspect" chipsets, how do I find out if the unit I
purchased is a lemon or not?
3.Is there a professional looking case for the device available anywhere?
Thanks for looking.
Best regards - John
