Analog Demodulation Measurement Application

Manufacturer's part number :


Manufacturer Agilent Technologies

Keysight Technologies

Description :

The analog demodulation measurement application is part of the common library of more than 25 measurement applications in the Keysight X-Series, an evolutionary approach to signal analysis that spans instrumentation, measurements and software. The analog demodulation measurement application expands the X-Series signal analyzers’ capabilities so that they function as easy-to-use analog modulation testers that provide fast one-button measurements for AM, FM, PM and FM Stereo/RDS signals. The measurement application also offers a variety of tools to make analog demodulation faster, easier, and more accurate, as well as helping 8901A/B modulation analyzer customers migrate smoothly to the X-Series.
