The Krytar 900B is a CW power meter engineered for precision RF and microwave power measurement across 100 kHz to 40 GHz. Built on a diode-based sensor architecture, it delivers ±0.05 dB linearity at 25°C with NIST-traceable accuracy and measurement speeds reaching 3 readings per second. The instrument combines laboratory-grade performance with field portability through rechargeable battery operation (12+ hours) and dual AC/DC power inputs, making it equally at home in benchtop setups and service environments.
