Anritsu expands Signal Analyzer MS2840A

Anritsu Signal Analyzer MS2840A Series
Anritsu Company has expanded its Signal Analyzer MS2840A family with the revelation of three new models supporting frequencies from 9 kHz to 3.6 GHz, 6 GHz, and 26.5 GHz.

The technology company has attempted to patch the gap for a cost-efficient, high-performance signal analyzer range that addresses middle frequency ranges.

The new products claim to provide an economical solution for precise measurement of wireless equipment, oscillators and other components for narrowband applications, land mobile radio, wireless backhaul, radar and automobile electronics.

The Signal Analyzer MS2840A models sport standard carrier close-in SSB phase noise performance of –123 dBc/Hz at a measurement frequency of 1 GHz and an offset frequency of 10 kHz.

The 3.6-GHz and 6-GHz products come with dedicated option for ensuring better performance to –133 dBc/Hz at a measurement frequency of 500 MHz and offset frequency of 10 kHz, an order of magnitude higher than current high end models.

The devices bear enough margin for accurate evaluation of spurious and phase noise of oscillators designed in wired and wireless equipment.

Also, the 3.6-GHz and 6-GHz models are configurable with an internal signal generator to provide output of both digital and analog modulation signals for an all-in-one platform to evaluate wireless TRx signals.

The Signal Analyzer MS2840A Series has standard built in options supporting versatile measurements, including instantaneous spectrum observation, Frequency vs Time, Phase Variation vs Time, and Spectrogram displays.

Vector modulation signal analysis software supports both digital and analog wireless modulation signals which can be evaluated by installing, analog measurement software, as well as amplifier noise figure (NF) measurement functions into the Signal Analyzer MS2840A family.

The  Signal Analyzer MS2840A series, which also includes an instrument that covers 9 kHz to 44.5 GHz has 4 options now. The common features of this platform include standard built-in functions for efficient measurement of Tx characteristics, including spurious, adjacent channel leakage power, spectrum mask, and frequency count.

The measurement platform of the Signal Analyzer MS2840A is claimed to be flexible for developing and manufacturing wireless equipment and devices.

By connecting the 26.5-GHz or 44.5-GHz model to an Anritsu High Performance Waveguide Mixer, such as the MA2806A (50 GHz – 75 GHz) or the MA2808A (60 GHz – 90 GHz), or an external mixer (≤325 GHz), the measurement frequency range can be widened and integrates with the sensitivity and dynamic range of the Signal Analyzer MS2840A series.

This configuration backs wide-dynamic-range measurements, as well as eliminates image-response effects when measuring wideband signals to implement efficient measurement for millimeter-wave wideband wireless equipment, such as wireless backhaul, automobile radar, and WiGig, said Anritsu.

Anritsu said the new analyzer also enables accurate evaluation of side-lobe characteristics of millimeter-wave radar antennas requiring high sensitivity.
