Hello again,
Yesterday I have finished to buid my second Digilite for 1255Mhz, SR4000.
I started as soon I plugged the DC power.
alignment again made with Tutioune, observing MER and constellations.
I can obtain 36dB Mer. The best we can.
and spectrum:
RF measured with SEFRAM give only -19dBm ( about 0.013 mW) I think too small ? What value must we expect at MAR6 output?
Digilite is a really good solution for DVB-S!
When software will be able to catch TS via UDP, I could stop to use my DTA107.

My Digilite test and aligment with Tutioune
Re: My Digilite test and aligment with Tutioune
-19dBm seems very low. Mine is about -7dBm. I'm using an MSA-0886 instead of a MAR-6, but the gain should be similar.
Maybe you have to trade MER against output level. What is your pk-pk voltage at the inputs to the AD8346?
