Performance Management
This tool enables the operator to see how the system is performing by
offering a series of strip charts (showing current data as IFU Link
Manager collects it) and historical plots.
Using the performance management tool, the operator can view the
following strip charts:
n Modem power and signal quality metric (SQM) data
n Block errors, modem lock status, and temperature
n IFU temperature plus the Tx, +12 V and -48 V statuses
Additionally, the performance management tool enables the operator
to plot the following data:
n Modem power defined by Received Signal Strength Indicator
(RSSI) in dB
n SQM in dB
n Reed-Solomon block errors from the modem
n Modem lock status in discrete values
n Internal temperature of the IFU
NOTE: Refer to the online help for more information about
performing these tasks.
