I am checking a tuned amplifier. A logarithmic frequency sweep would help. Prefererably in the device firmware
Beware of cheap underperforming clones
As of 2023 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.
See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

Logarithmic freq sweep anywhere?

Leif,
There is a firmware version for the V2 with log sweep from Oisijan:

I haven't tried it, but his earlier firmware version worked well and introduced other useful features.
