Data-acquisition system offers high channel count
The new MV200 from Yokogawa, with its large (10.4 inch) colour TFT screen, is a high-channel-count data-acquisition system that is equally suited to mobile or benchtop use.
The new instrument incorporates a rake receiver and compressed-mode monitoring capabilities, will follow base-station handovers, and will carry out transport-channel decoding and higher-layer analysis.
Air signal measurement is non-intrusively 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.
