Connection Test
The CoaXPress Host Interface of Coaxlink provides connection test facilities to test the quality up- and down-connections of the CoaXPress link according to the procedures defined in section 8.7 of the CoaXPress 1.1 standard.
For each individual CoaXPress connector, it implements
| ● | A test generator |
| ● | A test receiver |
The test generator transmits a Test Data Packet containing a known test pattern produced by a sequence generator. It increments the packet counter for each test packet transmitted.
The test receiver compares the received test data packet content against its local sequence generator. It increments the error counter for each word that is different in the data packet, and increments the packet counter for each test packet received.
Note: The test packet counters show how many test packets have been sent and received, so allowing a judgment to be made on the statistical meaning of the value in the error counter.
Note: Both Device to Host and Host to Device connection tests can be run at the same time.
