Hi guys

Does anybody know what is the symbol rate limitation in dual use for the TBS cards (in S2-8PSK) that just written "symbol rate 1-45Msps" on specification? For example 6909, 6902, 6522.
Thanks
 
A bit of a variable.

Have you worked any of the numbered cards outside the parameters provided ?

If not, why those specific models ?

It is pretty simple really: in the example, the minimum is 1Msps and 45Msps per demodulator.
With some driver hacking the 1Msps can be lowered to some lower value, which can be as low as 200ksps,
but then it is a matter of some luck as well as the card is operaterated out of spec

I didn't mean outside the range, for example, Can I get 2 different transponders with 45000 symbol rate one with Tuner 0 and other with Tuner 1 at the same time? Or using 2 tuners simultaneous limits tuners to lower symbol rate?
 
Official spec 1000-45000Ks for DVB-S/S2 QPSK/8PSK. For 16/32APSK and more some lower. All tuner/demods independed

Thanks, Mr CrazyCat, You always helped me❤️
How to demod tuners? And what are the cons? I couldn't find a source.
