For an amateur who will use it once a year, it says something about a professional. Nothing has gone wrong already three times, unreliable measurements on the ground. The company, as a service, is trying to do something but when the product doesn't do what it's supposed to, even the best can't help you

It has many capabilities (not necessarily useful as a field meter) and support from the manufacturer with firmware updates, but in my case the measurements deviate significantly from the result. I will focus on the DVB-T measurements: MER and constellation diagram are completely missing. The measurement at the antenna is 56dBμV level, 31db C/N, BER 0.00E-7. With these measurements, the bars are 84% level (!), and 90% quality. In the first cloudy weather, I have image breakups.

I contacted their technical service, in short, they measure what they measure (meaning they will never add MER measurement or constellation to DVB-T), they don't explain how they calculate C/N in digital and what it means (which is a measurement that comes from the analog era when the spectrum did not have many carriers) - so no one knows what is really being measured. When I asked why the quality bar does not become 100% when the BER becomes 0.00E-7, I did not get an answer (there was a mention that the signal level is involved (!) or that I see 0 but it is a small value).

In the discussion that as an amateur, if I rely on the 84% level and 90% quality, I do not have good reception for cloudy weather, we concluded that I lack knowledge and experience.

In general, for satellite (where there are more measurements) you will do something (as I did for NOVA/OTE and I have no issues with cloudy weather and rain). For terrestrial digital, you will NOT do the job, important measurements are missing and what is measured is not clear how they measure it, and the measurements do not seem to converge. For terrestrial, definitely get another device.

It is a fairly good instrument for its price. The battery, removable 6300mAh, lasts quite a long time, the indications are quite accurate, compared to very expensive instruments. It can be upgraded very easily and the edition supports it.
