The newest generation of ARC Detect? ARCNET network analyzers allow engineers to capture and decode low-level messages that controllers use to initiate and control a packet transmission. The ARCNET Network Analyzer (ANA) proves indispensable when examining the data sent over embedded ARCNET networks.
It provides the ability to view all frame types including Invitations To Transmit (ITT), Free Buffer Enquiry (FBE), Acknowledgements (ACK), Negative Acknowledgements (NAK), as well as the ability to view the transmitted ARCNET Packets (PAC).
Most analyzers only display transmitted packets because they incorporate an ARCNET controller chip for capturing packets. The ANA does not use an ARCNET chip but reconstructs complete ARCNET activity by observing the symbols on the cable. The ANA has a 2.5 microsecond timer resolution for all recorded events and will operate at the 10 Mbps upper limit of ARCNET.
This product operates on a standard PC or a notebook computer with a USB interface. It directly accommodates coaxial star and bus, twisted-pair and DC or AC EIA-485. Data rates can range from 156 kbps to 10 Mbps.
The ANA does not rely on the PC for real-time acquisition. Its USB module contains its own CPU, memory and custom triggering hardware to facilitate capture of all transmissions. Any unrecognizable transmission will be captured and displayed as well. This includes noise transients and reconfiguration bursts.
