Peak Power Solutions for Radar and Wireless Applications
Best Practices for Making the Most Accurate Radar Pulse Measurements
Introduction
Accurate and fast RF and microwave power measurements are critical in radar system life cycles. Power meters and sensors play a critical, yet most cost- effective role in measuring the output power from the radar system. As a long time, manufacturer of power measurement tools for the aerospace and defense industry, Keysight has the following invaluable knowledge to share on making optimal radar measurements accurately and effectively.
IEEE 1394 standard for pulse standard
The power envelope of a radar RF pulse can be analyzed using the IEEE standard 181-2011, “IEEE Standard for Transition, Pulses, and Related Waveforms.” Obtaining a common understanding of each terminology is critical to establish a common ground for parameter and performance comparisons. A list of some commonly used terms in radar pulse measurements are listed in the application note referenced below.

Single/Multi-Channel and Extended Distance Power Measurement with USB/LAN Power Sensors
Introduction
In today’s power measurement applications, there is a need to make multiple power measurements simultaneously. For instance, a base station commonly includes a compact equipment shelter or outdoor enclosure panels along with antennas that may be mounted on a roof, the wall of a building, or on a freestanding mast. A given base station may operate several channels (typically 2 or 3), where each channel uses a specific set of frequencies: one for the uplink and one for the downlink.

High throughput wireless test systems with up to 20 channels
The U2020 X-Series USB peak and average sensors perform fast and accurate peak and gated power measurements. These measurements are essential aspects of the production tests conducted for wireless signals used in cellular/mobile phone handset, wireless chipset, and amplifier applications. With plug-and-play USB connectivity, high measurement speed and multichannel capability, setting up a high throughput test system is simple, fast, and cost effective.
Remote testing for radar installation and maintenance
When a U2020 X-Series power sensor is connected to a LAN-USB adapter, you can perform complex radar pulse analysis and monitor your measurements from a distance up to 200 feet. The built-in internal zero calibration function allows you to permanently connect your sensor to the device-under-test without the hassle of constantly removing and re-installing your sensor.
