RF and Microwave Analyzer

RF (radio frequency) and microwave signal generators are used for testing components, receivers and test systems in a wide variety of applications including cellular communications, WiFi, WiMAX, GPS, audio and video broadcasting, satellite communications, radar and electronic warfare. RF and microwave signal generators normally have similar features and capabilities, but are differentiated by frequency range. RF signal generators typically range from a few kHz to 6 GHz, while microwave signal generators cover a much wider frequency range, from less than 1 MHz to at least 20 GHz. Some models go as high as 70 GHz with a direct coaxial output, and up to hundreds of GHz when used with external waveguide source modules. RF and microwave signal generators can be classified further as analog or vector signal generators.


The MS46121A is a series of two PC-controlled 1-Port USB ShockLine Vector Network Analyzers with frequency ranges of 40 MHz to 4 GHz and 150 kHz to 6 GHz. The MS46121A provides performance and accuracy for your 1 port measurements in a low cost and space saving solution that is small enough to directly connect to the device under test. All the members of the MS46121A series are aimed at RF and microwave applications in manufacturing, engineering and education. The two MS46121A options both come with 100 microsecond per point sweep speeds and a measurement accuracy of +/- 0.5 dB (-6 dB offset, typical), making them suitable for your passive device test applications.
