Optimized for Wireless LAN Testing

If you are designing wireless LAN (IEEE 802.11a/b/g) or

WiMAX (802.16e) components and subsystems, you will

need to analyze bursted signals. With 30 MHz of video

bandwidth, the P-Series power meters and sensors can

capture signal bursts and measure the peak- to - average

ratio of the transmitted power in your WLAN or WiMAX

products.

You can verify the power profile and output power of

WLAN components easily with the P-Series solution.

For example, because the length of a wireless LAN burst

is unpredictable, it is affected by the type of data being

transmitted and the data rates you are trying to achieve.

The P-Series power meter has an auto-pulse detect

fea-

ture that enables it to automatically capture bursts of

varying lengths, even when you do not know the parame-

ters of the signal.

By measuring the signal’s rise time and checking the

burst profile, you can identify any power transitions

that could cause interoperability problems. Measuring

the peak- to - average ratio and CCDF enable you to verify

that a power amplifier isn’t clipping.

The preconfigured presets for WLAN and WiMAX allow

easier capture of burst signals so you can get started on

your measurements sooner.

Versatile for R&D and manufacturing

The P-Series power meters and sensors can measure

all IEEE 802.11 WLAN signals. They can be used in

developing HiperLAN and HomeRF network devices

as well.

In component manufacturing, time is always money.

This is true in the high volume production of wireless

network devices and products where fast measurement

speed is essential to maximize throughput. Minutes

can be shaved from overall test times by combining the

internal zero and calibration capability with the fast

measurement speeds achieved through your choice of I/O

interface (LAN, USB, and GPIB) for data transfer.
