Setting Measurement Time

The Measurement Time setting allows you to alter the speed at which measurements are being made. Three choices exist: Slow, Medium, and Fast. The test set defaults to Medium. 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. Medium measurement time strikes a balance between measurement speed and measurement accuracy.
 Changes in measurement time, or measurement speed, are achieved by varying the amount of data used to plot the CDP trace, and by varying the type of frame alignment used. The table below shows this. .
Meas Time
 		Number of Slots
 		W-CDMA (HSDPA Off)
 		W-CDMA (HSDPA On)
Slow
 		2
 		Aligned to Scramble Sequence Frame (CPICH = 0)
Medium
 		2
 		Random Slot
 		Aligned to the start of the next sub-frame boundary
Fast
 		2
 		Random Slot
 		Random Slot

NOTE: CDP measurements will only meet Agilent's published specifications when you are using either Medium or Slow measurement speeds.
