Resetting Amplifier Capacity and Traffic Metrics
The amplifier capacity metrics such as the peak and average amplifier capacity and
peak and average utilization can be reset. If you prefer to reset these parameters
manually, you may do so using the [Reset Metrics] menu key. The test set may
automatically reset these parameters for you if you are using the PN Offset Auto
mode.
In PN Offset Auto mode, if the test set finds a new dominant pilot (from a stronger
base station signal), the peak and average amplifier capacity values will be reset.
The test set will decode the signal containing the new dominant pilot and gather new
amplifier capacity data for this signal. In PN Offset Manual mode if the test set finds
a new dominant pilot, the signal will not be decoded and the test set will display
noise in the code domain power display. The amplifier capacity metrics will be
unaffected and the test set will not gather data until the desired signal becomes
dominant again.
To Manually Reset the Amplifier Capacity Metrics:
Setting Measurement Time
The Measurement Time setting allows you to alter the speed at which measurements
are being made. Three choices exist: Slow, Average, and Fast. The test set defaults
to Average. Slow measurement time provides a more accurate measurement at the
expense of time. Fast measurement time provides a quicker measurement at the
expense of accuracy. Average measurement time strikes a balance between
measurement speed and measurement accuracy.
