TBS6925 1.0.1.7 beta driver

[steven]

Hi all

TBS6925 1.0.1.7 driver will be released soon, the new driver improves signal value and solves some other problems.
Please test it and your replies on this topic are welcome.

here is the download link:

Thanks

[tales21]

It worked very well
But still the problem of start-stop signals on some frequencies, especially on the scheduled 32apsk
thanks alot

[tales21]

at a frequency with Symbl rate 45000 signal backon with new driver
thanks alot

I don't know what You have changed in this version, but it brings INCREDIBLE speed up of signal locking! Crazyscan from Crazycat works with this drivers release MUCH faster, channel switching on all known DVB players is also faster, scanning is faster, everything is faster and still extremely stable. Well done! (Win7 x64)

Signal Level:

Ekhm, now I think that You have made it too good I got almost everywhere Level 95% and Quality 98%

At beginning I thought that maybe it would be good to use something like this:
- Signal Level: (100 - RF Level) * 1,4
- Signal Quality: Signal/Noise * 6 (and if it will give result more than 100 - cut it to 100)

but...

RF Level is not very good to rely on at TBS6925, differences between situation where signal is present and where it is not present are very small. At Hot Bird for 11,317V I got RF Level -40,708 dBm, at 11,335V (no signal - space between two transponders) I got -41.595 dBm. If i use my idea, I would have 83% level at 11,317V and... 82% at 11,335V, just 1% difference.

So maybe:
- Signal Level: Signal/Noise * 6 (and if it will give result more than 100 - cut it to 100)
- Signal Quality: 100 - (BER * 100)

As far as I know BER is represented in STV0903 as value between 0,0000000... (good) and 1,0000000... (no signal)? So in most cases I would have 100% (which would be true as no uncorrectable errors are in stream). I'm only afraid of situation where BER would be worse than 0,00000.... but not 1,00000... - I don't know how fast BER values are changing. If too fast - quality bar would be jumping like crazy and would be useless to fix dish pointing.

What do You think about this? Can You reveal (if it is not confidential information - if it is - forgot about this question) how do You now count Level & Quality?

I got almost everywhere Level 95% and Quality 98% ...how do You now count Level & Quality?

Only now I installed the latest driver.And if we look at signal bars as appears, seems to be the most sensitive ... tuner in the world. Indeed how we can realize quality signal if it is almost equal level?!Let us not make illusions, not so much tuner become more sensitive, but the software can give the appearance that signal increased.It is clear that we cannot take the bar of signal when we want to adjust precisely antenna.Apparent increase in signal yet look good, but we'll see when we'll meet with signal problems.In fact the value of a sensitive tuner is higher when lock weak signals and is stable.I speak now after the first impressions when I have not used more this last driver.

Yes, of course You have 100% right - that are only numbers. There are plenty of ways of counting them. Because of that (and fact that different hardware parts in different products can act differently), values between different products are completely uncomparable and of course these values have completely no impact on watching/locking possibilities.

Anyway these values sometime can help. If way of counting them is well worked out, I'm able to use them to precise my dish pointing. I'm using big 2m dish with 24'' actuator & positioner. As dish is pretty heavy - sometimes actuator will lost somewhere few impulses. When I will point dish by positioner I see some signal level & quality reported by drivers. If quality value is precisely counted - I see for example 67%, I'll try do add one impulse - 64% - wrong directory, so I stepping back 2-3 impulses - 70%, another impulse - 74%, another - 75%, another - 73% - whoops, need to roll back. And with that way, without connecting special measuring equipment I can be sure, that I fixed pointing at selected satellite position thanks to precisely counted level & quality values. So sometime this can be useful, but that are still just numbers, individual for every product

Hi DVB
I feel so happy when you say it is ok,and about the Signal Level and Quality advise,
We will have a test later,if it is good than before,we will use this
Really thanks for your test about the new driver.

Quote from other topic:

and would you mind try to test 1.0.1.8 driver.
here is the linker:

Thanks

Driver 1.0.1.8 rolls back speed improvements. These speed improvements won't be added to final version of TBS6925 driver?

Hi all,

Sorry for sounding daft, but how do you update to this driver and where does the .sys file go?

Thank you in adavance.

Regards,

Kev

From the windows device manager. Right click your device, select "update driver software", then "browse my computer for driver software", and point it to the folder where you have extracted your new drivers. You don't need to do anything with the .sys file, the update process will take care of it...
