The Emitor Satlook I use (NIT) has no digital circuitry that plays pictures, though it does have the constellation setting on the spectrum.
More interestingly , whilst it does not recognise S2 transmissions, it does a very good job at - almost - locking on the UHD stuff as you can see from the two constellations.
The MkIV does from the specifications show digital pictures, though the imagery confirms only an analogue display.
You would have to plug it in to a working dish to see the analyser does actually provide TV in digital mode ( A Freesat/Sky dish on your property ?) Regardless, it's not that important since the AD3000 will have the ability on SD transmissions.
Post a couple of pictures of the 4M dish face, along with the back mount and actuator system, a dish of that size really needs two motors to get the best out of it, even if perfectly aligned on the arc.
