The Bird® Model 4421 is a precision RF power meterthat, while originally intended for general purpose laboratoryapplications where high accuracy is required, has found wide acceptancein semiconductor processing applications. The product is configured as asystem, consisting of the Model 4421 digital display and a precisionpower sensor selected for the application based upon maximum power andoperating frequency.
- ±1% Accuracy — Accomplished through theuse of an automatic frequency compensation scheme, where the errorcontributions due to directional coupler frequency responsecharacteristics are eliminated
- Wide Dynamic Range — The instrument will meet the full accuracy specification over a 35 dB dynamic range
- Excellent Measurement Repeatability — Typically <0.1%
- Digital Display — Along with automatic VSWR calculation
