Figure 15 illustrates the LED panel for a SONET application in
TestPad mode.
If the instrument loses any of the LED events, the green
Status LED extinguishes, and the red Alarm LED in the history
column illuminates indicating an error condition has occurred.
For example, if the instrument detected a signal, but then
loses it, the green Signal Present LED extinguishes, and the
red LED in the history column illuminates. If the instrument
then regains a signal, the green Signal Present LED illumi-
nates, and the red history LED stays illuminated until you clear
history LEDs or restart the test.
ANT mode
If you specify ANT mode for the LED display, the LEDs illumi-
nate red when key events or errors occur. For example, if the
instrument does not detect a signal, the associated LOS LED
illuminates. When the instrument detects a signal, the LOS
LED extinguishes.
