Product Description

GEMINI™ 5540A RF Power Meter High Power, High-Accuracy RF Measurement in a Single Instrument

0.2 to 200 MHz, 3 to 5,000 W

Designed from the same dedication and expertise that built the TEGAM calorimetric instruments used in primary and production labs around the world, TEGAM’s new GEMINI 5540A RF Power Meter¹ brings modern functionality and easy-to-use design to the world of in-line RF power measurement. Ideal for use in semiconductor applications where measurement uncertainty and repeatability are imperative, the GEMINI 5540A RF Power Meter is a measurement tool you can trust.

The 5540A is suitable for the most demanding applications with a 2-sigma accuracy of ±0.5% + 0.5 W across its power range. It combines the sensor and meter into one convenient instrument, allowing technicians to read forward and reverse power, VSWR, and frequency simultaneously on the large, easy-to-read OLED display.

It is powered by a standard USB 2.0 port, external battery, or AC power outlet using off-the-shelf USB adapters. And since the meter is built-in, there is less equipment – and less cables – to carry to the field or bench.

Real-time readings and data collection increase user productivity and process efficiency. Use TEGAM’s GEMINI Tools RF Power Meter Application, or write custom applications with the 5540A’s command set.
