An electromagnetic background level meter?

Question

Iron

I want to buy an "electromagnetic background level meter" to measure EM fields for compliance with state standards.
Let's say I decide to live in close proximity to the Ostankino tower on the 10th floor with windows on the tower
and I want to be sure that the EM background complies with the standards.
I also want to measure radiation from a system unit, microwave oven, and other objects of EM wave radiation.
I looked after myself such a device - ATT-2592
but, firstly: it is up to 3.5 GHz, but I would like up to 5-10 - to measure WiFi (802.11a / ac).
secondly: I am a complete layman in such devices and in guests.
Therefore, the questions are:
1. What kind of guests are there in Russia, America and Europe?
2. What device to buy for "home" experiments? It is desirable that it signalizes when the norms are exceeded and that it is possible to limit the measured frequency to a custom range (for example, measure only WiFi).

Answer 1

ATT-2593
I think just under your requirements.

Answer 2

Unfortunately, the Aktakom company supplies them, only on order with an expectation of 4-5 months.
Maybe someone knows analogues, albeit foreign, but so that you can freely buy? Well, or at least order from ebay / amazon / etc.

Answer 3

Found this option on Amazon:
