SPECTRUMANALYZERS

SPECTRUM ANALYZER

GPIB Ethernet

MS2681A/2683A/2687B

OPTION

9 kHz to 3/7.8/30 GHz

For Evaluation of IMT-2000, Bluetooth™, MMAC and Advanced Radio Communication Devices

6

The IMT-2000 (2 GHz band) service for third-generation mobile radiocommunication has started. Bluetooth has been adopted for close- range radio communication between portable remote terminals and peripheral equipment, and R&D of MMAC, IEEE802.11a, and HiperLAN2 (High Performance European Radio Local Area Network Type 2) for higher speed access have been conducted in various countries. The MS2681A/2683A/2687B spectrum analyzer delivers optimum performance over a wide dynamic range (156 dB, typical value), wide resolution bandwidth (20 MHz), to high-speed sweep (refresh rate of 20 times/s), required for evaluating next-generation radio communi- cation systems and devices. It can be used not only as a spectrum analyzer but also to perform various measurements easily and quickly by installing measurement software.
