Precision Power Meter for Semiconductor Processing Applications
• ±1% uracy - 完成 through the use of sensors with an
automatic frequency compensation scheme, where the error contributions
due to directional coupler frequency response characteristics are
消除。
• Wide Dynamic Range - The instrument will meet the full uracy
specification over a 35 dB dynamic 范围。
• Excellent Measurement Repeatability - Typically <
• Digital Display - Along with automatic VSWR calculation
• Computer Interface - RS-232 and IEEE-488 standard
The Bird® Model 4421 is a precision RF power meter that, while
originally intended for general purpose laboratory applications where
high uracy is required, has found wide eptance in semiconductor
processing 应用. 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 频率。
