New NS2000 (NS3 / NS4) thread

[duaneclaude]

You must setup your RX8200 to get the signal from ASI instead of satellite.
From the web interface select Input > ASI, then Apply and check again.
Also, remember that all 3 BNC connectors on the RX8200 can be switched between ASI in/out and SDI out, so check carefully that the connector you want to use as ASI input is properly configured.

The rx 8200 has a asi in bnc connector , thats what I connected the sdi cable to.
Set the the input to asi too.
Even tried with a s2 signal but no lock.
Could it be a setting in the ns3000 ?

Another problem that I need help with.
I have now connected the ns 3000 to an rx8200 with an sdi cable.
connected to tx asi A on ns3000 and set input on rx 8200 to asi.
I have freq 11221 on 7 East locked, but rx 8200 says unlocked.
Am I set up correctly ?

75 or 50 ohm cable? im sure i read in the ns3000 manual asi is 50 ohm

Thanks for reply, will look at cable tomorrow.

A picture is attached below showing the picture output of a single channel from an NS3 six channel mux received by one of the NS3000 units recently listed on eBay.

Those NS3000 units are both Rx (receive) and Tx (transmit) for DVB-S2, DVB-S2X, NS3 and NS4. They also have Rx/Tx capability up to and including 64APSK and SR of 80000.
That is a fairly high specification, quite a way ahead of an NS2000 unit which is receive only. My understanding was that the eBay NS3000 units were pulls from an NBC working environment, probably explains the high specification, NBC purchased them as "fully loaded" or thereabouts.

Mine isn't S2x, it is listed in the modulation on the line but if I select it , I, get a message saying "This unit is not licenced" or something like that.

Doh, you are correct, even though DVB-S2X is listed in the modulation list the NS3000 is not licensed for it, just tested it.
I was assuming it was licensed for it as the NS2000 I have here has it in the modulation list and it works OK.

It is just a small reduction in the spec of the eBay NS3000 units, the main modulations of NS3 and NS4 are working on both the Rx and Tx side.

whats the max transfer rate the altronica can push through with the usb2 bottle neck?

whats the max transfer rate the altronica can push through with the usb2 bottle neck?

Never tested it, it was pushing through at approx 93mbps in the picture I uploaded earlier today.
The maximum theoretical data rate for USB2.0 is 480mbps and the fattest EBU hypermux is 200mbps so it should cope with that in ASI format?

cool, i thought it may run out of bandwidth. alot of pci asi devices are rated in the 200+ mbit range so was expecting usb 2 to fall short of that.

I have now got this ns3000 connected to the rx8200 using asi, but only with a dvb S2 signals.
When I have the ns3 11221 frequency on 7 east locked, the rx8200 doesn't see it. Anyone got any idea why.

I believe that 11221V is NS4, not NS3.
Remember that sometimes the signal seems synced or locked although the modulation is not correct, so if it does not work try to change between NS3 and NS4.
Also, did you configure the ASI out? It must be enabled in the Novelsat menu.
So check if ASI A or B (the out you are using) is enabled and assigned to Channel-1.

I thought that if the dvb S2 signal arrives at the rx8200, then the asi out must be configured correctly.
Will try ns4 for 11221. Ta.

Yes you are right. If you get DVB-S2 the ASI out is OK.
So the problem could be only between NS3 and NS4, try both.

Not really getting enough time to use it at the moment, just an hour here and there.
Got 10 days away from work in early september, when I hope to get to grips with it.
I understand I'm not going to get pictures, but I should be able to get a lock on both units.

 

[duaneclaude]

Finally managed to get them connected with the ns3 11221 H signal.
Now if I had the biss key would I have a picture ?

Yes for all of them except the "Director" encrypted channel, highlighted in the screenshot below.
Please note each different channel in the mux uses a different key, it is not the same key for all channels in the mux.

I have attached below a picture showing a couple of of Novelsat feeds from 100.5 East.
The feeds are not newly found as they were recently reported on Flysat. The frequencies I measured the feeds at were 4077V and 4176V respectively.

The 4077V feed has fairly high carrier width, around 70MHz or a little over that and is reported on Flysat as an EBU feed.
That carrier width is similar to EBU Hypermux 6 found in Europe on 10.0 East so it may be a repeat distribution into Asia?

.

 

[moonbase]

Another NS4 feed found on AsiaSat 5 at 100.5E.
Frequency is 4157V, SR is probably 70000 ksps.

There are a few pictures attached below showing the feed in the AVCOM spectrum analyser and its lack of a lock in CrazyScan and IQMonitor.

.

 

[duaneclaude]

What spectrum analyser is suitable for spotting these frequencies ?
Will a 2nd hand S2 unit be ok?
There's some old promax meters on the sale site.

What do you mean by an S2 unit?

Any RF scanning analyser should show a peak for Novelsat feeds, after all, they are just a carrier signal in the L-Band RF spectrum.
The dynamic sweep of the spectrum by an analyser does not distinguish between modulation types such as Novelsat, S2X, DVB-S2 etc, it is simply scanning for carriers.

PC apps such as CrazyScan which do a single pass scan do not provide the resolution of a spectrum analyser, you need something with a decent dynamic refresh rate to get good resolution.
Check out the difference between CrazyScan and the AVCOM unit in the pictures I uploaded today, The AVCOM unit with decent dynamic refresh rate has a lot better resolution of the spectrum.

I have a Promax Ranger Neo+ spectrum analyser and it detects them OK as should any half decent meter.
The issue is recognising which spectrum peaks could be Novelsat and which are not.
