Optimized for Multi-channel Power

Amplifier (MCPA) Testing

The base stations that support today’s high capacity

wireless networks must handle a growing number

of data channels. Rather than incorporate a separate

amplifier for each channel in the system, engineers

are streamlining their designs by using multi-channel

power amplifiers (MCPAs). If you are designing or

manufacturing MCPAs, you need a wide bandwidth

tool that can measure the peak and average power or

peak- to -average ratio to verify that your product does

not exceed maximum power specifications. The P-Series

power meters and sensors offer a complete power

measurement solution with a 30 MHz bandwidth. It can

measure peak and average power of up to six 3G (5 MHz)

carriers over a wide –35 to +20 dBm dynamic range, more

than enough for power amplifier testing today and in the

future.

Accurate power measurements

The accuracy of power measurements is a major concern

in high data rate wireless applications. With the P-Series

products, you can accurately measure the linearity of

power amplifiers (input power versus output power) at

the 1dB compression point.

The P-Series flat video bandwidth helps to ensure

the accuracy of your peak and peak- to-average ratio

power measurements. Agilent characterizes the P-Series

sensors over their specified temperature, frequency and

power ranges. These correction factors are stored in

EEPROM, so that along with an average power

measurement accuracy specification of ≤ ±0.2 dB (refer

to Data Sheet 5989-2471EN) you don’t have to worry

about the affects of error on your measurement.

Multi-level, TDMA power testing made easy

The P-Series power meters provide four independent

time gates (A1-A4) in a single measurement setup

(see Figure 5) so you can choose where you locate your

measurements of peak, average, and peak- to-average

ratio on the trace.
