Bird - 4027F SeriesPrecision Filtered RF Power Sensors Filtered Power Measurement for Critical RF Applications The Bird 4027F Series RF Power Sensors are designed specifically for use in semiconductor processing and other precision process applications where the effects of amplitude modulation and harmonics need to be eliminated from the measurement. Because accuracy is critical, these sensors are capable of ±1% accuracy at the calibrated frequency and power level. Calibration is traceable to the National Institute of Standards and Technology (NIST), providing additional confidence in sensor measurement.

PRODUCT FEATURES

• Provides filtered measurement where the effects of amplitude modulation and harmonics need to be eliminated
• ±1% accuracy at specified frequencies and power levels minimizing poor production yields
• Models do not need to be field calibrated before use and only need to be calibrated once every six months
• Plug and Play with the 4421A Series Multifunction Power Meter
• Dozens of connector options available
• Calibration traceable to the National Institute of Standards and Technology

FOR USE WITH

• 4421A Multifunction Power Meters
• SCC7 Calibration Cart
• MSCC7 Calibration Cart
