Setting Rx optic limit
A RRH has a finite dynamic range for input optic power and it can cause an abnormal behavior of the RRH if
the optical power is weaker than certain level. To differentiate intermittent low optic power issues from any
RSSI, interference and signal quality issues, it is important for you to monitor the input optic power level
during the monitoring of the spectrum and the signal quality. Using this Rx optic limit feature, you can set
lower and upper limits and monitor the Rx optic level with Pass/Fail indication in green and red colors.
Procedure
1
Press the
LIMIT
hot key.
2
Press the
Rx Optic Level
soft key.
3
Set a threshold for
High Limit
and
Low Limit
.
4
To enable the Rx optic limit, toggle the
Test Limits
soft key to
On.
If the optic power level falls out of the specified thresholds, the color of the power reading or
indicator turns red.
5
To disable the Rx optic limit, toggle the
Test Limits
soft key to
Off.
Setting BER limit
You can set the BER (Bit Error Rate) limit and monitor it in the BERT displayed on the screen.
Procedure
1
Press the
LIMIT
hot key.
2
Press the
BER
soft key.
3
To enable the BER limit, toggle the
Test Limits
soft key to
On
(default).
4
Enter a value between 1 to 1e-15 by using the rotary knob. You can also use the numeric keys
and then press the
Enter
soft key.
5
To disable the BER limit, toggle the
Test Limits
soft key to
Off.
Setting RTD limit
You can set the RTD (Round Trip Delay) limit and monitor it in the Counts displayed on the screen.
Procedure
1
Press the
LIMIT
hot key.
2
Press the
RTD
soft key.
3
To enable the RTD limit, toggle the
Test Limits
soft key to
On.
4
Enter a value between 0 to 1,000,000,000 by using the rotary knob. You can also use the
numeric keys and then press the
Enter
soft key
5
To disable the RTD limit, toggle the
Test Limits
soft key to
Off.
