Loop Display Sequence
After the unit has displayed the boot-up sequence it proceeds to the
loop sequence. In this mode the LCD displays the actual module
status as depicted by the diagram below. This information is referred
as the loop sequence because this information is constantly displayed
in a scrolling fashion on the LCD readout. The loop sequence may be
interrupted at any time by pressing any of the arrow keys. In the loop
sequence the back light LCD is off; however, after pressing any navi-
gation button the backlight automatically turns on for ease of viewing.
During the loop sequence the LCD displays 3 valuable parameters for
each installed (present) AQT module. Modules "NOT PRESENT" will
not have information displayed during the loop sequence.
• Input: Displays the actual input signal to noise ratio (SNR) if locked
• Output: Displays the channel number the output is programmed
• Input Freq: Displays the center frequency of the input signal
