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. In channel mode the
tuning frequency is defined by the active channels table (CCIR, ...).
Key number 0 to enter numeric data.
[25] AUTO IDENTIFICATION / EXPLORATION
•
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: DVB-C /
DVB-S / DVB-S2 and all the associated; parameters such as the carriers
2k-8k, the symbol rate, the code rate, etc... and it tries to lock to the signal.
In the case of DVB-T / DVB-T2 signals the equipment locks automatically the
signal without previous identification, which implies that the user does not have
to select any parameter of modulation, with the exception of the channel
bandwidth.
In the spectrum analyser and measurements 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.
