Setting Averaging

---

You can choose to have averaging On or Off and to set the number of averages you want to take. Averaging only applies to the data, not the trace. When initialized, the Agilent E7495A/B defaults to running average:

• A running average computes the new result as the weighted sum of the last result and the new measurement. The last result is weighted by (n - 1)/n. The new result is weighted by 1/n. Each new measurement produces a new result.

Averaging applies to the following measurement metrics and the control channel view only:

• Freq Error
• Noise Floor
• EVM
• PCDE
• Carrier Feedthrough
• Chan Pwr
• CPICH power
• all the delta powers
• Control Channel Graph

The following measurements are never averaged:

• CDP Trace
• Threshold

To set averaging:

	Step	Notes
1	Set the number of averages. [Average] Enter the number of averages using the numeric keypad. [Enter]
2	Set averaging On or Off. [Average/Sweep] [Averaging] [Off] or [On]

NOTE:

These two steps can be performed in any order. However, if you turn averaging on and a large number of averages has previously been set, there may be a delay before you can change number of averages.
