Advantest Launches Microwave Spectrum Analyzer

Tokyo -- Advantest Corporation recently announced the addition of its new portable spectrum analyzer, the U3771 (supporting frequencies up to 31.8 GHz) / U3772 (supporting frequencies up to 43 GHz). The U3771/U3772 can be operated on battery power, making it suitable for monitoring the microwave and milliwave bands that are used in satellite transmissions and between cellular telephone base stations.

At 308 cm (W) x 175 (H) x 209 (D) and less than 6 kg, Advantest claims its new U3771/U3772 portable spectrum analyzer is the smallest in the world to support measurements from 9 KHz to 31.8 / 43 GHz. Its newly developed input circuitry system fits into a compact casing. Designed for field use, the U3771/U3772 can operate either on an AC/DC power source or on a battery with a life of approximately two hours. Likewise, its warmup time is less than five minutes.

While the U3771/U3772 is lighter and more compact than previous models, it features a full suite of measurement functions including channel-power, frequency, adjacent-channel power, and occupied-bandwidth. A high sampling rate provides improved measurement repeatability of 0.01 dB, permitting the U3771/U3772 to make power measurements that previously required a power meter as well as a signal analyzer. It features, moreover, a highly sensitive input (<117 dBm @ 34 GHz: Typ) that enables it to detect weak signals and take measurements under a wide range of indoor and outdoor conditions.

The U3771/U3772 features a LAN port as well as a GB-IB interface. Measurement data can be transferred to the customer's computer environment for ease of management.
