Hello

Very often people ask me : TT S2-1600 Vs TT S2-3200 . Which is the best?

I can say that:
>>> S2-3200 cost twice the price of S2-1600
>>> S2-3200 use STB0899 -second generation of demodulator chip
>>> S2-3200 STB0899 can decode DVB-QPSK signal down to SR=800 kS/sec
>>> S2-1600 STB0899 Derotator can lock a signal far up to 600 kHz
>>> S2-3200 use STB6100 tuner chip that has a step size of 26.4 kHz and scan only standard band L : 950 MHz to 2150 MHz
>>> S2-3200 has an extension connector for the use for descrambler cards

>>> S2-1600 cost half the price of S2-3200
>>> S2-1600 use STV0903 -third generation of demodulator chip
>>> S2-1600 can decode DVB-QPSK signal down to SR=270 kS/sec
>>> S2-1600 STV0903 Derotator can lock a signal far up to 2.8 MHz
>>> S2-1600 use STV6110 tuner chip that has a step size of 843.75 kHz and can scan from 600 MHz to 2600 MHz
>>> S2-3200 has an NO extension connector

I really prefer the S2-1600 that lock more quickly on the frequency, work from 600 MHz to 2600 MHz and is more sensible and can lock a signal at SR 270 kS/sec!

Today I have connected my dish, during one ISS pass, to 2 PC with both cards.
So each card has received same signal.

the result:

S2-1600

S2-3200

Little better for S2-1600 when signal is very low. But no so much differences in a real test as I believed.

I will show also the video of both TiouneMonitor during the ISS pass.
