4.3 Menu functions

After start up, the equipment display shows information regarding the main
operating conditions, as can be seen in the following example:
FREQ: 650000000 Hz ATT: 10 dB
FFT:8K CONST:64QAM BW:8 MHz GUARD:1/4
FREQ: 650000000 Hz ATT: 10 dB
TEST: NONE
Here the RF frequency is 650 MHz, the 1-dB step RF attenuator is set to 10 dB,
the DVB-T signal has 8K carriers, occupies 8 MHz and uses a 64 QAM constellation
with a guard interval of ¼. No test mode is selected (NONE) and the operation mode of
the MO-170 is set to master. Packets of length 204 bytes are currently being detected
on the TS input selected by the user.
After a few seconds, the display changes its contents to show the working time
and error count information, as follows:
MO-170
Working: 01:13:55 ERR: 0
The text on the upper line (the name of the company, in the example above) could
be customised via the RS232 port to the user's needs, allowing for an easy
identification of the equipment or for some piece of advice.
Pressing the MENU key, allows us to enter the main menu level. Pressing MENU
again, takes us to the main status display. This main menu level uses the first text line
to give some advice on the operation assigned to each control, and the second line to
display the selectable options and functions.
MENU: back PUSH: select TURN: next/prev.
