HP 8935 Series Base Station Test Solution E6382A GSM Test Set

[ Summary ][ Features ][ Specifications ][ Key Literature ][ Ordering ][ Assistance ][ Related ]
The HP E6382A is a field ruggedized, easy-to-use, base station test set for GSM900 and DCS1800 networks. It has been designed to help GSM base station Installation and Maintenace Teams get reliable test results quickly and easily. The HP E6382A combines comprehensive test functionality, automated and manual ease-of-use features, and rugged packaging under a single handle. This new GSM tester combines HP's expertise in GSM measurements, and experience with base station test for other wireless formats.

The HP E6382A GSM base station test set provides all of the functionality needed to measure transmitter, receiver, combiner, and associated antenna performance. It offers frequency coverage from 0.4 MHz to 1 GHz and from 1.7 GHz to 2 GHz. Manufacturer specific software, available now for Ericsson base stations, automatically configures the test set and provides graphical information about the RF and Abis connections, so that technicians can quickly connect to the base station.

Maintenance technicians can use the test set for out-of-service functional and parametric tests, and they can perform RF measurements in-service, while the base station is live.

The HP E6382A has a spectrum analyzer, built-in source, and downloadable software that can be used for swept antenna measurements and cable-fault location. HP can also supply optional connector and cabling kits that contain everything needed to hook up to a particular manufacturer's base station and begin testing.
