That may be true now but with the constant advance in technology and miniaturisation it seems quite likely future developments will add a substantial range of test capabilities to miniaturised NVA's. This will not be welcomed by manufacturers of expensive single purpose devices. Basically the hardware and software requirements for spectrum analysis within these NVA's lend themselves to adding RFI analysis capabilities to these test instruments.

Subject: Re: [nanovna-users] NanoVNA Is it possibel to add RFI capability
The NANOVNAs are not the proper instrument to use for sleuthing RFI. A
battery powered receiver in the AM band is excellent. Also, the TinySA is
a small highly affordable spectrum analyzer which is suited for the
purpose.

So many smmall devices and somjetimes power supplies generate RFI.
Would it be possible to add a sensor to assist in detection, identifion
and measuring RFI from such devices.
Seems a logical extension but I do not have technical skill to know how it
might be doen.
It would certainly need something to prevent the Nanovna being overwhelmed
by powerful signals.
Would be really useful to have such capability in the shack
