Anritsu MA2481A Universal Power Sensor

The Anritsu MA2481A is a universal power sensor designed for accurate and reliable RF power measurements. It is intended for use with Anritsu ML2400A and ML2430 series power meters. The MA2481A combines the fast response time and low power sensitivity of a conventional diode sensor with a wide dynamic range, utilizing True RMS detection for comprehensive power analysis. This makes it suitable for testing and calibrating RF equipment, particularly for modern communication technologies such as 3G GSM, HDTV, point-to-point radio, EDGE, and digital audio broadcast, which often employ complex modulation schemes.
