SNR value in decibels.

This information is not provided by the BDA driver. Therefore not possible.

(Some drivers my provide this information in a non standard way. But then you will need a specialised program.)

I agree.

 

However, can be given limited support anyway.

 

So, there must be a way for some tv cards ...

 

Or, as ebspro, analysis tools, it can be utilized in dB signal imaging.

 

The purpose was this; BDAs does not give a realistic level signal.

 

It is between, db level ; 0 - 18 ... And possible to always realistic.

 

As a result; A solution must be produced.

Sorry...

 

Formulation like this;

 

Decibels [dB] = 10log10 ( A/B ) - 10 is the logarithm to the base 10 of the ratio of A to the value V.

SNR = 10log10 (Signal / Noise)

 

If Signal = Noise, the SNR = 0, but this is not the least important! The lowest value of SNR → -∞ when Signal → 0 and Noise → ∞

The maximum SNR value is not restricted (formally).

 

 

As a result;

 

dB denominated; practically max. 24 dB. It is possible to see the value. I consider it so.

 

Anyway...

 

Purpose; signal level as possible, to be able to see close to the real level.

 

I would appreciate could be added.

 

Regards.

While any frequency; "SNR dB value" can be imaged simultaneously.
,
Example; Prof 7301 HD TV card + EBSpro ;

rVGX01.png

 

 

3 samples for different devices;

 

Sample frequence; Turksat 11096 H 30000

 

1) Sathero SH-300 ; 11.80 db.

 

2) Dreambox 800se, M801A Alps tuner ; 12.20 db.

 

3) Prof 7301 tv card, STV0903bab demod ; 12.00 db.

 

As can be seen, the values are too close together.

 

Therefore, the most realistic signal level is obtained by the still decibels.

 

If you are able to adapt to this feature, I'll be really happy.

They are using driver specific functions. Not standard BDA driver interface. And only possible with few cards.

So that is not possible with all card and need to be impermanent on a per card or vendor basis.

Implementing that would be a lot of work. And you would need to search for that information for every new card.

I doubt that such support will come.

Tjod is right. We have no resources for that. Please use other / special tools for this purpose. Don't expect DVBViewer to cover these needs. You would be waiting for Godot.

Whether or not it can be difficult, "TJOD" explained already.

 

What do you mean "Godot" ( ! ). Are you kidding me. If you do not like it, you do not answer.

 

You're spoiled, I understand from your message.

 

Also; "Godot," I read.

 

Thereafter, you name; Griga = Godot

"Waiting for Godot" is a saying for waiting for ever.

And by the way Griga is the developer, how mostly would implement such things.
