Promax TV Explorer

Recommended Posts

I paid 16550,- NOK ex.VAT, that is about 3280 Australian Dollar. All software included.

Just tried with latest firmware, V5.00, and found a new menu under, DiSEqC settings called 'SATCR'.

Anyone knows what this is for?

regards,

Satz

Hello Satz

I don't now abouth the settings called 'SATCR' but

I wonder if you can help me with a copy of PKTools

Ad. PKtools

I have tested the PRODIG- 5 for almost 1 year, but not before I upgrade

the software to ver 5.0 i got what I realy needed.

Before I have to use my Promax-8 for sampling data.

Hi!

We purchased the TV explorer about 4 month ago, we are using it since then. Quite happy with it. The only problem I have is how to update the satellite and other lists, I heard about this pktools that could help me in this.

Oivind or Satz could one of you send me a copy to my email?

Thanks a lot. (lmarton@mail.tvnet.hu)

Hello Emerson

Yes I will send You a copy of PkTools,

Withthe PkToll You will be able to change or update the sattellite or other frek. list.

It is also possible to copy the mesurement to PC and from there make prints.

Oivind, I haven't received anything yet :blink:, if you'll have a little time please don't forget me :D

Hi, just sent both of you the program.

CBER is channel BER and is the Bit error RATIO of the signal before any form of error correction .

VBER is viterbi BER and is the Bit Error RATIO of the signal after it has passed through the Viterbi error correction section of the meter,(Digital STB,s also have this )

MER is modulation error ratio and is a figure which is ment to represent all impairments to the signal.

We have Promax 10 Premium.

Does anybody know what difference between MER measure algorithm for firmare versions 5.94 and greater (for example 6.12)?

The results are different for ~7dB.

The last version shows better MER results at the same cable.

Does exist calibrated MER source/generator?

Or I can only suppose that the MER at the good headend is about 39dB,

and more close to this value result is more correct?

Hi,

As far as i know, such a generator does not exist and the reson is quite simple and has got to do with what affects the MER measurements.

MER takes into account, among many other things, noise within the channel, what most people do not take into account is that when the signal enters a level meter, it goes through a lot of electronics and, among them, an attenuator set. All of htis will add noise (and the less noise it adds the more $$$$$ the machine will cost you) into the system and thus, what the tunner and later demodulator sees is not exactly what the signal entering the meter was.

Two exact same tuners and demodulators placed on two different meters will not necessarely measure the same MER. This does not really make one meter worst than other, as long as MER values are consistent (better signal.....higher MER). Obviously this has to be put into perspective as if a meter reads 30 and another one only reads 22, there is a problem with one of them.

Ideally, MER should have an infinite value, but noise is always present. R&S for instance does not have an MER generator, but has a C/N (in channel noise generator) which makes it almost the same as they are assuming nothing else is affecting their signal (phase and/or imparements). I guess then, that would be the closest you can get to a MER generator.

A meter that measures a value of 40 dB's compared to another one that measures a value of 38 on the same signal does not make one true and the other untrue, if it means anything at all, is just that one adds less noise to the system than the other, but the optimum installation can be accomplished with both of them.

Cheers

There are much text :blink: . I see contradictions.

Can I suppose the next situation is all right:

I measure MER=28dB at the CATV outlet, then I upgrade meter's firmware and the result changes to 35dB.

I think that one of firmwares has an error. I want find out which result is more correct.

What I can use as the simple generator with known MER?

Is it only expensive vector generator? Or I can use something else?

Don't have experience with this meter, but if it's designers are able to determine the quantity of noise which is introduced by the meter on the signal, they can substract that via software and therefore achieve higher MER's. I would say the higher value is the correct one in this case but, as I said, cannot be sure.

If you want to make sure, get a SFQ from R&S (go to some lab which has one) and make the measurements.
