Test 9: Concatenated message test B to A
1 Application
To test the ability of a receiving FX919B or FX929B to acquire and read a message when
switched onto a stream of continuous concatenated messages which do not include Symbol
Synchronisation patterns.
2 Description
This test transmits a continuous stream of short concatenated messages without intervening
Symbol Sync patterns from channel B. The receiving channel A device repeatedly acquires
messages (using AQSC, AQLEV and SFS tasks) then reads the body of the message and checks
it for errors before performing another acquire. The test reports the number of messages
transmitted, the number received and any CRC errors in the received data.

4 Test
Sequence
Because of its complexity, it is not practical to document the complete test sequence. Instead,
refer to the sequence documented in Section 4.6.6 Test 6: "BER & DQ test 'B' to 'A' using
formatted messages" for a representative sequence of modem control.
5 Error
Codes
Similar to the error codes for Test 6 , see Table 20.
Test 10: Concatenated message test B to A with Rx signal monitoring algorithm
This test is similar to Test 9, but also includes the Rx Signal Monitoring Algorithm as described in Section
1.6.6 of the FX919B and FX929B Data Sheets. The report displayed at the end of the test also includes a
count of the number of re-acquisitions forced by the algorithm.
