Power Meters & Power Sensors

Power is a fundamental parameter that characterises the properties of microwave signals, and its precise measurement is a critical aspect of modern microwave measurements. The microwave power meter is the foundational measurement device among instruments measuring microwave power characteristics.

Ceyear Technology has a long standing commitment to researching microwave power measurement technology a nd developing related products. Our product portfolio includes microwave power meters, USB power sensors , LAN power sensors and more. Operating across the DC to 110 GHz frequency range, we deliver flexible, scientifically rigorous measurement solutions that are tailored to the specific testing requirements of power measurement applications.

Microwave power meters enable the accurate measurement of various parameters, including average power, peak power, peak to average power ratio (PAPR), pulse width, rise time and pulse period. Key specifications include a single probe maximum average power dynamic range of 96 dB, a maximum peak power dynamic range of 55 dB, broa dband coaxial frequency coverage of up to 110 GHz, a rise time of ≤13 ns and a minimum measurable pulse width of 50 ns.

Ceyear Technology utilises the 2439D microwave power meter as the base platform, paired with USB power sensors from the 87233, 87235, 87 236 and 87237 series, for performing average and peak power measurements. These USB power sensors can also connect to computers, laptops, or other Ceyea measurement instruments.

87245 and 87246 Series LAN power sensors connect to computers via PoE switches , enabling power monitoring up to 60 metres away. This makes them ideal for scenarios requiring long distance power measurement transmission, such as production line testing, field testing, and remote monitoring.
