The LB5940A is a high accuracy True-RMS power sensor for general purpose use. The sensor utilizes a highly accurate, thermally stabilized, two path, RMS responding, square law diode detection scheme. The sensor makes accurate measurements on any signal regardless of its modulation bandwidth. The sensor’s patented thermally stable technology means that measurements do not drift and user zeroing and calibration before use are eliminated. Measurement interruption due to automatic calibration is also eliminated, bolstering the performance and reliability of ATE systems. The company’s PMS-12 Power Meter Software is included. The sensor is useful for research & development; manufacturing & service applications, including radar, satellite, telecommunications; 802.11 testing, etc.
