[QUOTE="vma, post: 806144, member: 256592"] Hi, As far as I know, there isn't currently a single satellite, which does not have at least one DVB-S transponder. This means that a meter with DVB-S2 is nice to have, but not a requirement to align a dish. Regarding the Satlook Lite, check the manual: _http://www.doebis.de/sites/messgeraete/mess_datenpdfs/satlook_lite/Satlook%20Lite%20Manual.pdf The meter is not bad, however you need to be aware that the spectrum is not rendered in real-time. This means that you cannot just setup your dish using the spectrum. For amateur users I would rather recommend a second hand Satlook Digital NIT or, even better, the Satlook Digital Color or Satlook DIgital Color HD (this one is suitable for DVB-S2). If you just want to adjust the alignment of the dish, you are set with these meters. However, if you need to trace faults, especially with DVB-S2 transponders, then you need better equipment. Because DVB-S2 carries so much more information, it has actually a worse error correction, which means that the signal has to be received in better conditions compared to DVB-S. Here lies the advantage of having a DVB-S2 capable meter. You will benefit of MER, BER and constellation of the 8PSK signal. This will tell you if the antenna is poorly aligned, or if other problems occure, like: - incorrect tilt of the LNB - bad cable - etc. Meters like this cost 10x or mor than a Satlook Lite, so my guess is: just go for that or look for second hand Satlook Digital NIT/Color/HD. A bit more expensive, but more professional: Rover Instruments. Cheers, vma [/QUOTE]
