4.2.1 Screen Saver Display

Upon powering up the BDA, a display resembling Figure 4-2 appears on the LCD panel:

Figure 4-2: Screen Saver Display

The ﬁrst row contains the network name of the BDA; this allows the user to determine which BDA they are viewing.

This name can be changed to whatever the user desires and can contain blank spaces, capital letters, lowercase

letters, and numerals. It is limited to seven characters to facilitate communication with a web monitor, should one

be desired.

This screen is known as the Screen Saver display because it is the screen that the BDA will revert to showing if there

has been no activity detected on the keypad for at least ten minutes. If this occurs, the LCD backlight shuts off to

save power and prevent the backlight from burning out. Pressing any key other than

Edit while in the Screen Saver

display will turn the backlight back on, and advance the menu to the Power Readout display. Pressing the Edit key

will advance you to the Edit menu series.

4.2.2 Power Readings Display

This menu shows the instantaneous Power Readings in the BDA, as well as whether or not the gain is being actively

attenuated by automatic gain control.

Figure 4-3 illustrates a typical Power Readings display:

Figure 4-3: Power Readings Display

The power reading display in Figure 4-3 shows that the composite power is currently 19 dBm on the output of the

uplink pass band, 27 dBm on the output of the downlink pass band, and automatic gain control has attenuated the

signal 2 dB on the downlink pass band.

Note that when the power through a channel is less than 0 dBm, the display will show <00 in the location where the

reading usually appears. This prevents spurious power readings from occurring because of random noise.

The Up, Down, and Save buttons have no effect in this menu, but pressing the Menu button will advance the user

to the event readout displays.
