5.5 Automatic Transmission Search
Holding pressed the [25] key search starts over the active channel plan.
When tuning a channel the instrument tries to identify it and save it with the
configuration. If the identification is not possible the channel is removed from list. As a
result obtains a new channel plan that only contains the channels that have been
identified.
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 [20] to switch between analogue and digital channels. Press the
[20] 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 US TV
EXPLORER II activates the last measurement configuration used for that type of signal.
5.7 External Units Power Supply
The US TV EXPLORER II 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 labeled 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 supply
voltages:
