Verify the logic analyzer performance
The logic analyzer performance verification (self-test) is divided into two
sections. The first section tests the physical connections such as the cable
and termination. The second section tests the internal functions of the LAN
interface. When both sections of the self-test have finished, a status message
appears in the LAN Test field. The status message indicates whether the test
passed, if a failure occurred, and which section failed.
The physical connection test depends on the LAN topology used. If ThinLAN
is used, then a test transmission signal is transmitted over the LAN. If a reply
is received, then the physical connection is considered good. If EtherTwist
(10Base–T) is used, then the logic analyzer will listen for the heartbeat signal
from the LAN. If a heartbeat is received, then the physical connection is
considered good.
The second section is tested using internal loopback features of the LAN
hardware. Transmitted packets are looped back to the receive circuit of the
LAN board. When the looped-back packets are received, they are processed
like a packet received from a remote client or server. If the looped-back
packet is recognized and processed, then the LAN board and the LAN
software are considered good.
Perform the following check before beginning the procedure.
Check all network cables and connectors. Verify that all cables are
properly connected.
