View Full Version : ET9000 Blind Scan
Blind scan has been briefly mentioned in other threads but it is such an interesting subject for feed hunters it would be nice to get some grouped information on the ET9000 and also the ET5000. Can someone do a test of a known satellite and time it? Do a full blind scan from 10.7GHz through to 12.75GHz, and symbol rates 1000 through to 30,000. Also post the number of TV, radio & data channels found on that satellite.
Also anyone who owns one of these and a Vu+ can they rate the tuner of the ET compared to the Vu+.
Thanks, and any comments welcome.
I'll give this a test, but tbh the settings confuse me lol. I'll post a screenshot so peeps can advise the settings.
Here's the screenshot that I posted in the et5000 thread (as that was done on my et9000). As Sic says, the settings aren't the easiest, lol...

I'm happy to test on ET5000 and 9000 if someone can point out the correct blindscan settings please.
As Sic says, the settings aren't the easiest, lol...Ok, it looks like the frequency settings are IF. I'll come up with some numbers for that.
What are the options in "polarity" and "scan band"?
To be honest it looks like half arse blind scan support ie the box does not have the hardware to support true blind scan and is relying on a software solution.

Polarity options = horizontal, vertical, circular left, circular right
Scan Band - low, high

Here something about ET9000 Tuner :
DVB-S2 Channel Receiver AVL2108
BENEFITS
● Advanced demodulation technology achieves 120Mbps (45 MSps) 8PSK data rate which is 150% of similar products
● Powerful LDPC/BCH FEC decoder for all-weather signal reception
● Typical power consumption is less than 850mW. No exposed pad required.
● Fast acquisition allows wide frequency uncertainty
● Robust timing and frequency synchronization accommodates low-cost LNB
● Robust symbol timing recovery loop and carrier tracking loop to handle the worst case phase noise
● Compact 12x12mm LQFP 80-pin package.
● Automatic identification of modulation mode and FEC code rate reduces workload of host software
AVL2108 Based DVB-S2 Frontend
FEATURES
● Fully compliant with DVB-S2 standard Broadcast Profile, supports QPSK and 8PSK demodulation
● Integrated dual ADC with DC component cancellers, IQ imbalance compensator, and phase imbalance compensator
● Fully supports DVB-S legacy standard
● Built-in RF AGC circuit, directly interfaces with a variety of tuners
● Symbol rates from 1MSps to 45MSps for all modes including 8PSK modes
● DiSEqCTM 2.0 compatible LNB controller interface
● FEC decoder code rates: DVB-S2: 1/2, 3/5, 2/3,3/4, 4/5, 5/6, 8/9, 9/10 DVB-S: 1/2, 2/3, 3/4, 5/6,7/8
● Parallel/serial output data interface, output bit stream retiming
● Roll-off factors for pulse shaping, 0.2, 0.25, 0.35
● Standard two-wire serial bus with four selectable addresses
● Signal quality monitor and lock detector
● Power saving mode
● Automatic blind signal identification scan for all supported modes
Hi
The Tuners are very very good,
I made a test with my DM8000 and my ET9000
I find more channels in the low frequency range and generally more stations,
I think these are the best tuner in the E2-Area
Ok, here are some settings to try just to try to figure out if we are on the right track. I'm trying to work out if those frequencies are IF or real. The spaces are just to make the numbers more readable, so when you transfer them to the box don't leave any spaces. You might have to left pad those numbers with zeros.
Start freq: 950 000 000
Stop freq: 1950 000 000
Polarity: vertical
Scan band: low
Low SR: 1 000 000
High SR: 30 000 000
Satellite: use 28šE would be good because it is a satellite most people have access to.
Hi
Most people have access to 19.2 E, but for the English-People is of course important 28 E (Sky-UK),
I will test it, when I have a bit more time.
in hispasat i scanned more 7 tv CH and 15 Radio BlindScan !!:thumbsup:

Did a quick scan earlier using the settings u posted. Got 190 channels I think it said. Can't remember name of channels or how long, but didn't feel too long ... about 2 mins or so...
Will try again later and post screenies, time it, etc...

That sounds pretty impressive, but it is only scanning 1/4 of the satellite (vertical low) so a full scan might be 8 minutes (which is pretty reasonable). We'll know for sure when you put a stopwatch on it. What is really nice though is SR is customisable, which is a feed hunter's dream.
So assuming the settings I posted above were correct for low band, the following settings should work for high band.
Scan band: high
Start freq: 1100 000 000
Stop freq: 2150 000 000
Low SR: 1 000 000
High SR: 30 000 000
Using those settings and the ones above to do a complete search you would need to do four scans: low band/vertical, low band/horizontal, high band/vertical & high band/horizontal. I hope this makes some sort of sense.
No chance to scan tonight... Sorry...
No chance to scan tonight... Sorry...No rush mate, it would just be nice to get as much info on this function as possible, because, as far as I know, no other E2 receiver has it.

what is it u want to try i will be giving my et 9000 a scan i can try it for ya

Hi,
What images are you using for the blind scan, I thinks that you has to use the new VIX image when it becomes out soon ?? Or can you blind scan with any images? I thinks that the blind scan was not running OK until new images were available.
I am making some decision on the ET9000 or the VuDuo but the blind scan on ET9000 if running with any images is a good choice for me :confused:

Blidescan is running on the ViX ET9000 image currently being worked on. Wont be long now.

or is it just me

If you've got the latest beta image on your box, it should be there. Just go to service scanning. I chose manual scan, and change it to blindscan...

Will the blind scan run on other images from other developments like Pli and blackhole or are these other developments waiting to give new images to get the blind scan running?
My wife who leaves me had blackhole in her box but not sure if she she used it for blind scan, it did pick up a lot of stuff though.

Should run with Pli images, not blackhole as their image is too dated now. I believe BH stopped producing images for the the ET's.
hi can some on put some video for blindscan is it work well or what thankssss
Is Blindscan working for anyone on the latest image?

Blindscan is working on the latest Vix image :)
How is the tuner setup as I've tried everything but keep getting error "the tuner is not configured properly"
I've tried USALS, Single, Advanced etc still can't get it to work

Blind scan works amazing on this box. Ive got the xtrend9200silverline and blind scan is fast and the tuners are sensitive. Great hardware Blindscan . Cant beleive how fast it is even with the 1000sr setting

Now all the settings have been converted into numbers people understand.
something that no ones clarified, is it only tuner a that blind scan works on....when i try on tuner b, it gets no services found...
something that no ones clarified, is it only tuner a that blind scan works on....when i try on tuner b, it gets no services found...Not sure on the Xtrends. On the blindscan capable Vu's the plugin works on all internal tuners. If it doesn't on the Xtrends that is going to be a hardware or driver issue.
Thanks
