Setting the Multipath Power Limit

---

Multipath Power is only relevant to Over the Air measurements. It does not apply to Transmitter measurements.
Multipath power is the amount of power, of the dominant pilot signal, that is dispersed outside the main correlation peak due to multipath echoes (expressed in dB). Ideally, this value should be very small (< 0.1 dB). Multipath power is the result of portions of the original broadcast signal arriving at the receiving antenna out of phase with the main power of the original signal. This can be caused by the signal being reflected off objects, such as buildings, or being refracted through the atmosphere differently from the main signal. These out of phase signals can cancel power from the main signal or appear as noise interference at the receiver.
If the measured Multipath Power meets the limit you have set, the numeric result displayed in the OTA PN Scanner section of the screen is displayed in green. If the measured Multipath Power fails to meet the limit you have set, the result is displayed in red font, and all metrics displayed in the metrics portion of the screen will be displayed in gray. This is to indicate to you that the metrics you are seeing are unreliable because the Multipath Power limit has not been met.
To Set the Multipath Power Limit:

	Step	Notes
1	[Setup]
2	Press [Mp Pwr].	Specify the Multipath Power Limit level in dB. The minimum setting is 0.0 dB, and the maximum setting is 2.0 dB
