6.13 ISDBT (VB256 Option Module for VB220)
The ISDBT tab will be present in the graphical user interface provided that the probe chassis is equipped
with an optional ISDBT demodulator module. The VB256 has two RF inputs per module. Each ISDBT
tab represents an independent RF input.
ISDBT1 is the leftmost input as seen from the front of the unit. There can be up to four ISDBT tabs
(ISDBT1 through to ISDBT4) depending on card configuration and licenses.
For the VB256 one input is active by default and the second input can be activated through the SECOND-
RF-INPUT-OPTION license key.
Thumbnails for the RF demodulated services are accessed from the
