Keysight Average Power Meters

This video introduces Keysight Average Power Meters, designed for dependable and accurate measurement of continuous‑wave (CW) RF signals in wireless communications, radar, aerospace, satellite systems, and precision electronics testing. These instruments provide stable, high‑accuracy power measurements across broad frequency and dynamic ranges, making them essential tools for characterizing transmitters, verifying signal chains, and ensuring compliance in both lab and field environments. Low‑noise circuitry minimizes the impact of signal fluctuations, ensuring reliable results even under dynamic test conditions.

Average power meters support dynamic ranges from –70 dBm to +44 dBm, enabling precise measurement of both extremely low‑power and high‑power RF components without requiring additional attenuators, preamplifiers, or multiple sensors. Broad frequency support up to 220 GHz—when paired with the appropriate sensors—future‑proofs test configurations for 5G, automotive radar, satellite link characterization, and emerging high‑frequency applications. These meters also include real‑time calibration via auto‑zeroing, continuously correcting internal offsets and drift to maintain stable baseline readings.

Keysight offers a comprehensive suite of compatible power sensors—including average, peak, diode, thermocouple, wide dynamic range, and waveguide sensors—ensuring accurate measurement performance tailored to each application. Average sensors excel at CW measurements, while peak sensors enable time‑gated and transient‑power analysis. Diode sensors provide high sensitivity for low‑power testing, and thermocouple sensors deliver robust environmental stability. Wide dynamic‑range and waveguide sensors support specialty and high‑frequency measurements. These capabilities make Keysight Average Power Meters a versatile and reliable platform for modern RF power measurement needs.

Key features include:

• Wide Dynamic Range: Measure signals from –70 dBm to +44 dBm without external attenuators or preamps.
• Broad Frequency Coverage: Support frequencies up to 220 GHz using compatible sensors for 5G, radar, and satellite applications.
• Real‑Time Calibration: Auto‑zeroing continuously corrects offsets and drift for stable baseline readings.
• Low‑Noise Circuitry: Ensure stable, accurate measurements under fluctuating or dynamic signal conditions.
• Sensor Ecosystem: Compatible with average, peak, diode, thermocouple, wide dynamic‑range, and waveguide sensors.
   

Average Power Meters provide reliable, high‑accuracy CW signal characterization with wide dynamic range, broad frequency support, and real‑time calibration. Paired with Keysight’s extensive sensor portfolio, they deliver stable, precise results for lab, production, and field‑based RF testing.
