Bird Model 4421 Laboratory Grade RF WattmeterBird 4421 Series Laboratory Grade Power Meter (Used)
(Used - In Excellent Condition)
The Bird Model 4421 is a precision RF power meter that, while originally intended for general purpose laboratory applications where high accuracy is required, has found wide acceptance in semiconductor processing applications. The product is configured as a system, consisting of the Model 4421 digital display and a precision power sensor selected for the application based upon maximum power and operating frequency. Accessories Options:
- +/-1% Accuracy (Sensor Dependant) Accomplished through the use of an automatic frequency compensation scheme, where the error contributions due to directional coupler frequency response characteristics 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.
- Power Sensors Sold Separately.
