S2438 Series Microwave Power Meter

S2438 series microwave power meter is composed of a host of microwave power meter and a series of microwave power sensors. S2438 series have a wide frequency band, large dynamic power range, high precision, fast measurement and analysis, serialization of sensors. It is mainly used for measuring and calibrating the average power, peak power and pulse envelope power of microwave signals. S2438 series is an important measurement instrument for the research, production, acceptance and maintenance of radar, electronic countermeasures, and communications.

S2438 series is a good suitable of Keysight N1911A/ N1912A/ N1913A/ N1914A.
