USER'S MANUAL. US TV EXPLORER II
Key number 8 to enter numeric data.
[23] ANTENNA ALIGNMENT
Tool for faster sweep antenna alignment at terrestrial and satellite bands.
Displays the measurements by means of a graph level bar.
Key number 9 to enter numeric data.
[24] TUNING BY CHANNEL OR FREQUENCY
Switches tuning mode between channel and frequency. (quick pulsation).
In channel mode the tuning frequency is defined by the active channels table
(FCC, ...).
It visualises the listing of channel plans available (slow pulsation).
Key number 0 to enter numeric data.
[25] AUTO ID/ EXPLORER
Activates the automatic identification function (short pulsation):
The instrument will try to identify the signal under test.
First it recognises whether the signal is an analogue channel or a digital one.
If the channel is analogue, it determines the television standard of the signal
detected.
When the signal is digital, it analyses the modulation type: QAM Annex-B /
QPSK / 8PSK / 8-VSB and all the associated parameters such as the symbol
rate, the code rate, etc.,. and it tries to lock to the signal.
In the spectrum analyser mode it appears on screen the name of the network
and the orbital position (only in satellite band).
Activates the band exploration function (long pulsation):
The meter explores the entire frequency band to identify the analogue and
digital channels present.
