5.6 Selecting the measurement configuration: Analogue/ Digital signal
Measuring the characteristics of a channel depends, in the first place, on the type
of modulation: analogue or digital.
Use key [17] to switch between analogue and digital channels. Press the
[17] key to show the measurements CONFIGURATION menu and select the
Signal option by turning and pressing the rotary selector [1]. The Signal option
allows setting the type of signal to measure. When switching to a new type, the
TV EXPLORER HD ISDB-T/T

activates the last measurement configuration used for
that type of signal.

The TV EXPLORER HD ISDB-T/T

can supply the voltage needed to power the
external units (antenna preamplifiers, in the case of terrestrial TV, LNB in the case of
satellite TV, or IF simulators).
In order to select the supply voltage of the external units, press [11] key, and
the screen will display a functions menu labelled EXT. SUPPLY listing the choice of
voltages (which will depend on the band being used). Turn the rotary selector [1] to
the desired voltage and press to activate it. The following table shows the choice of
