Versatile tester for IEEE-1394 bus
The new FireWorks 1394 VK9000 from Yokogawa Martron is designed to provide engineers with a powerful 'out of the box' solution for testing systems based on the IEEE-1394 bus.
The new instrument incorporates a rake receiver and compressed-mode monitoring capabilities, will follow basestation handovers, and will carry out transport-channel decoding and higher-layer analysis.
Air signal measurement is nonintrusively carried out without any direct connection to BTS (Node B) or UE, and analysis is provided for protocol layers 1, 2 and 3 on both the uplink and the downlink.
The main unit connects to the controlling PC via an Ethernet interface and TCP/IP sockets.
Powerful Windows 2000 based software provides parameter setting, profile graphs, code searching, physical and transport channel views, and RLC/RRC/NAS message decoding and display.
Applications include the verification and testing of mobile phones and base-station equipment at the development stage or in the field, protocol software debugging, and measuring-instrument verification.
