Precision Power Meter for Semiconductor Processing Applications
4421 Multifunction Power Meter is a precision RF instrument 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 4421 and a precision power sensor selected for the application based upon maximum power and operating frequency.
- ±1% Accuracy - Accomplished through the use of sensors with 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
- Computer Interface - RS-232 and IEEE-488 standard
