Setting the Slot Threshold Level
The Slot Threshold is a level, measured relative to the idle power, that determines
whether a slot is idle or non-idle. When the power in a slot is greater than the Slot
Threshold, that slot is determined to be non-idle. When the power in the slot is less
than, or equal to, the Slot Threshold level, the slot is determined to be idle.
To Set the Slot Threshold Level:
Setting the CDP Type
The CDP Type parameter is used to specify whether you are despreading Pilot,
MAC 64, or MAC 128 codes when you are performing your measurement.
NOTE Rev 0 of the 3GPP2 (Third Generation Partnership Project 2) standards requires 64
MAC codes to be despread; Rev A requires that 128 MAC codes are despread.
To Set the CDP Type:
2. Enter the Measurement
Offset using the numeric
keypad.
The maximum value you can enter is 15.
