1xEV-DO over air measurements provide a quick method of verifying 1xEV-DO transmitter performance. These transmitter measurements can be made on a base station from the convenience of your vehicle without taking the base station out of service. Over air measurements are especially useful in maintaining hard-to-access cell sites such as pole-top base stations.
The 1xEV-DO Analyzer and Over Air option may also be used to measure signals at a coupled port on the transmitter.
Important metrics for both Tx and Over the Air measurements include:

• Frequency Error
• PN and Time Offsets
• Non Idle Power
• Idle On/Off Ratio
• Pilot + MAC power
• Pilot Rho (estimated)
• MAC Rho (estimated)

NOTE:

To achieve valid over-the-air measurements, the test set must be stationary (not moving).
