Performance Message Screen


The Performance Message screen shows the current performance metrics and the screen is updated each time a new PM event is raised on the element. Each filed is described in the table below.

Item

Description

Input

Identifies the specific input being reported on:

  • RO-A is Cesium connected to Remote Oscillator A input

  • RO-B is Cesium connected to Remote Oscillator B input

  • GNSS is input associated with GPS Antenna connection

Index

This is an integer value in range that increments each time the RO metric data is recomputed.

Order

Specifies the most recent performance metrics data result for RO-A/RO-B/GNSS.

The meaning of the values is:

  • 0 = most recent update

  • 1 = update 1 minute prior

  • 2 = update 2 minutes prior

  • 3 = update 3 minutes prior

  • 4 = update 4 minutes prior

Status

This is used to specify general status of information in the associated row.

Average Frequency

Average frequency of RO in ppb

1Min MDEV

1 minute tau MDEV for RO (X.YYYYYY), in ppb

20Min MDEV

20 minute tau MDEV for RO (X.YYYYYY), in ppb

1Day MDEV

1 day tau MDEV for RO (X.YYYYYY) in ppb

Tracked Satellites

Average value of tracked satellites (XX.YYY)

Tracking Density

Tracking density value (X.YYY)

Dispersion

Dispersion measure value (XXX.YY)

Note: In some systems with older system software version (1.0 or previous versions), the Performance Message details will not be shown to user.
