This is about 950MHz so the HackRF outputs up to 15dBm. The DVB-S unit (SatLink WS-6906) is rated -65dBm to -25dBm, and also sends out DC power for a LNB. The attenuator should block 50dB of the DC, but I’ll check with a meter. So if I feed this from the HackRF through a 50dB attenuator to the DVB-S unit is there anything obvious I’m missing before I get to the magic smoke expedited egress event?

Instead of hard wiring through - feed the hackrf through your 50db attenuator into a 50 ohm dummy load - place the receiver at the other end of the test bench - move
rx closer until you hear a signal?
