Promax TV Explorer

Recommended Posts

I spoke to Promax a week ago and they informed me that this new TV meter was in full production and that many units were already being sold. There was a backlog of about 1 month before they could deliver a new unit.

I wondered if anyone has tried these yet? They look mighty fine from where I am standing.

Comments? I am in the UK by the way, and the retail price here is £1500 + 17.5% VAT

Any web links?

Technical specifications as distinct from glossy presentation?

Haven't been able to find them, but not for lack of looking. Like to see more than pretty pictures and highlights of some of the instrument's operating parameters.

(My spanish friend tells me noticias = the news. I want data from whence to derive my own interpretation of the facts.)

Didn't think there was any interest as kept getting referred to the glossy brochures - I have a thing about that. :blink:

Comments would be appreciated.

Thanks a lot, if you can and have it, can you give me a contact person (name and email) at Promax.

As far as specs go, it seems to me as an excellent meter, it's got the accuracy (on paper), its got the spectrum, BER/MER, MPEG-2 and it weights 1.9 Kg.

I'm really looking forward to see it working, if it is half as good as they say, I'm seeing bad selling times for the Unaohms as, personally, I prefer one meter for all than one meter for each modulation, specially with this weight.

Cheers

Just got a price and demo from Electrocraft for 4.2K + GST, and what can I say, the meter really does the job.
