Precision RF Power Sensor Family

When accuracy is critical, Bird’s Precision CW and Pulsed RF Sensors deliver. Built for semiconductor fabs, test labs, and precision manufacturing, they combine metrology-grade performance with real-world durability and easy integration.

With accuracy options of ±3%, ±1%, or ±0.5%, each sensor is NIST-traceable and supports both CW and pulsed signals. Advanced features like gated time-domain analysis and microsecond-level resolution give you the flexibility and confidence to handle today’s calibration demands—and tomorrow’s.

Two Sensor Families.
One Standard of Trust.

One Sensor, All Signal Types

Pulsed & CW
RF Sensors

For engineers working with—or moving toward—more complex RF waveforms, Bird’s CW + Pulsed sensor family provides the added flexibility to handle dynamic signals with confidence. These sensors bring advanced measurement capabilities like time-domain analysis and pulse insight, helping you stay ahead of process changes while protecting your long-term investment.
