Advantest R4131D 3.5GHz Spectrum Analyser

Advantest R4131D 3.5GHz Spectrum Analyser Description:

• Frequency range of 10kHz to 3.5GHz
• Resolution bandwidths from 1kHz to 1MHz
• DANL of -110dBm or less
• 5.5 inch CRT display
• GPIB interface, Field strength & quasi-peak measurements as standard

The R4131 Series incorporates the performance of the already-popular TR4131 Series of 3.5 GHz spectrum analyzers and provides additional features as well.

Weighing just 10 kg (22 lbs], these analyzers have a measurement condition memory function which includes waveforms, an auto-recall function which recalls measurement conditions when power is switched on and other features to simplify operation. In addition to these new features, these analyzers use the proven spectrum analysis expertise of ADVANTEST, with standard features of directly readable field strength measurements compensated for antenna calibration factor and quasi peak value measurements conforming to CISPR standards.

The R4131 series features a maximum input sensitivity of -116 dBm, a dynamic range of 70 dB and a skirt characteristics of -80 dBc or better. Especially, the B type analyzer provides AFC (Automatic Frequency Control), enabling highly stable spectrum analysis. The TR4153A/4153B and TR4154 Tracking Generators can be added to these analyzers to enable frequency characteristic measurements with a wide dynamic range. For use in measuring systems, GPIB is as standard, as well as direct plotting and video output for use in system applications.

The R4131, weighing just 10 kg, covers the wide frequency range of 10 kHz to 3.5 GHz, and is designed for both high performance and portability. The R4131 can be used in such diverse applications as 3rd harmonic measurements of 900 MHz-band mobile radio equipment, received field strength measurements of satellite broadcasts and evaluation/ maintenance of CATV systems.

The R4131 consists of 8 models, enabling selection for various application requirements. All models feature high performance and set of features and functions for various applications.
