There is always changing data on I and Q, except in TEST MODE = NO MOD, even when the USB and SD card are not connected.i have observed in the osciloscope that i have digital output signal pins 18 and 22 for "Q" and also on pins 21 and 23 for "I" when I have not connected the USB and SD card, it is correct?
Also when i have not connected the USB ans SD card, I have a digital modulation in the spectrum analyser. it is correct?
and, other question that i have, when i begin to send packet PC to PCB, i don't see output packet in the PC screen. it is correct?
For other test modes, there are single lines on the analyser and not normal modulation.
Does DigiLite transmit say "Looking for recording". If it does, then WinTv is not recording. Can you show a picture here of your DigiLite Transmit screen.
