 If you are using a Ryde, Portsdown or Minitiouner receiver you will be able to enter the frequency and symbol rate directly and just go to receive.
-If you are using a set-top box, you must add the wanted signal frequency to the LNB local oscillator to find the frequency you must tune to.  For example if you are wanting to receive a signal on 1249MHz and the STB is set for an LNB LO of 9750 you need to tune the receiver to 10,999 MHz.

 You will need the normal aerials, filters/pre-amps and/or LNB depending on the band you want to receive. Having said that it is relatively sensitive enough on its own to be able to receive nearby activity - and probably your local digital TV repeater.

 You can use a consumer STB to receive DATV but most set-top boxes do not go below 1 Msymbol or 1 MHz bandwidth and most DATV signals use rates less than this.

 Since the release of Portsdown software in autumn 2019 that included the LongMynd receiver you can plug the MiniTiouner USB tuner hardware in to the Portsdown system and it will display the pictures, thereby becoming a full DATV transceiver and replacing the need for a PC.
-Note you can not use the Pluto or Lime SDR to receive DATV signals but they can be used to provide a band viewer.

 The Portsdown 4 software includes everything you need - just make sure you have the latest build - and plug your tuner card in to the Pi's USB port.  See https://wiki.batc.org.uk/Portsdown_4_Pluto for more details.
