Spectrum measurement frequency extended to mmWave band with external mixer

Anritsu Corporation has released enhanced software functions for its signal analyser, the MS2830A, MS2840A, and MS2850A. These enhancements allow the analysers to extend the spectrum measurement frequency range to encompass the mmWave band by connecting VDI or Eravant external mixers.

mmWave sensing device can detect subtle changes in human body surfaces generated by breathing and heartbeat and identify the position of people and objects. These advancements open up new applications in diverse fields, such as medical care, automotive, and facial-recognition security systems. The company contributes to developing a safer and more secure society by providing solutions to evaluate mmWave band signals and improving mmWave device quality.

The growing demand for sensing technologies using mmWave radar, particularly in the 60GHz band, has driven advancements in medical applications. This technology is also employed in facial recognition security systems. Furthermore, automotive radar technology is undergoing advancements with the development of wideband 79GHz band radar capable of detecting small targets such as pedestrians and bicycles at high resolution.

Simple solutions are required to measure transmission signal characteristics to evaluate sensors designed to accurately detect mobile objects and automotive radars using ultra-wideband mmWave signals.

The company's mid-range benchtop MS2830A, MS2840A, and MS2850A signal analysers provide high-performance capabilities and comprehensive options for wireless signal measurements across diverse applications. These models span the RF to microwave/mmWave frequency bands and accommodate narrow- to wideband signals.

For spectrum, signal, and phase-noise measurements, the measurement frequency range can be extended by installing Anritsu's External Mixer Connection Function MX284090A. This function supports the connection of a recommended external mixer from Eravant or VDI to the signal analyser's 1st Local Output port.

The MS2830A offers outstanding cost-effectiveness and is appropriate for various applications, including R&D, manufacturing, and maintenance.

The MS2840A stands out with its excellent phase noise performance and provides a comprehensive suite of options to support higher-performance measurements. These options include 2dB attenuator resolution and noise floor suppression.

The MS2850A signal analyser function supports signal analysis at bandwidths up to 1GHz.
