6.15 SAT (VB272 Option for VB220)
The SAT tab will only be present in the graphical user interface provided that the probe chassis is
equipped with an optional DVB-S/S2 demodulator module.
The VB272 DVB-S/S2 option module offers two independent RF input modules. For the VB272 one input
is active by default and the second input can be activated through the SECOND-RF-INPUT-OPTION
license key.
If demodulator cards are present in the chassis each RF input will be labeled SAT1, SAT2 up to SAT4 in
the case of two VB272 modules being installed. SAT1 being the leftmost, as seen from the front of the
unit.
Thumbnails of SAT services are accessed from the
ETR 290 — Services
