Another test on Eutelsat W2A at 10.0°E (no feeds). With the reference a complete scan of 27 transponders was performed in 70s. It took the TBS 8921 3 times longer (210s) with 8 missing results [X] out of 27 ;(

According to the specs the card should be able to receive and demodulate DVB-S2 carriers between 1MS/s and 45MS/s. I could test one transponder with 45MS/s. The card locked within 3s which was only a fraction slower than the reference. The reason could be related e.g. to different diseqc timing. TBS sends a burst after the diseqc command according to the diseqc bus specs. Most other cards I know don't.
A totally different situation for DVB-S2 carriers with very small SR. Down to about 2MS/s the card will lock with an error free output mux, though it takes much longer than the reference (8s vs. 3s). Below around 1800KS/s the output in case of a lock is not reliable any more. It's impossible to determine the exact limits without a DVB-S2 multiplexer and modulator. I have to use real satellite transponders
Back to the 0100.ini (see above).
11161H, qpsk, 1320, 5/6 was locked by the reference in 8s with an error free output. After fiddling with the frequency (frequency bug) the 8921 showed an output signal after 15s, but this output was garbage:
