FarSync BERT Tester – PCIe

A Bit Error Rate 2 port sync line quality tester for a Windows PC/Server with a PCIe slot. The FarSync BERT provides a comprehensive, simple to use, all in one, line testing utility for testing synchronous lines from your PC. There are no extra expensive modules to buy to test different line types.

Product Summary

The FarSync BERT provides a comprehensive, simple to use, all in one, line testing utility for testing synchronous lines from your PC. There are no extra expensive modules to buy to test different line types. All the popular standard BERT test patterns can be selected; the test period can be controlled; real time error counters and full line test statistics are provided as well as support for user controlled error injection.

Lines with network interfaces RS232 (V.24), V.35, RS530 (EIA530), RS422, X.21 (V.11), RS449 and RS485 (4 wire) can be tested with line speeds ranging up to over 10 Mbits/s.

The FarSync T2Ee adapter is fitted in one your PC’s PCIe slots; select one of the cables provided to connect to the line to be tested; the BERT application can then be started and the line quality results are displayed in real time. Multiple FarSync BERT products can be run from a PC.

There is API access for LabVIEW or Windows applications, this allows programmatic control of when tests are run, the tests to be run, and the results obtained.


Technical Functionality

Test Patterns

A wide variety of pseudo random and fixed test patterns may be configured on the FarSync BERT used to test the line. ITU compliant test pattern recommendations are supported, these are compatible with other industry standard BER Testers.

Synchronous Lines

The following pseudo random patterns are ITU-T compliant, they are used to test synchronous lines:

  • 63: 26−1 – including a max of 5 sequential zeros and 6 sequential ones
  • 511: 29−1 – including a max of 8 sequential zeros and 9 sequential ones
  • 2047: 211−1 – including a max of 10 sequential zeros and 11 sequential ones
  • 215−1 – including a max of 14 sequential zeros and 15 sequential ones
  • 220−1 – including a max of 19 sequential zeros and 20 sequential ones
  • 223−1 – including a max of 22 sequential zeros and 23 sequential ones
  • QRSS: 220−1 – modified to transmit a maximum of 14 consecutive zeros

The following fixed patterns can be used to test synchronous lines:

  • 1:7 (1/8, 1-in-8) – 1 mark followed by 7 spaces
  • 1/16 (1:15, 1-in-16) – 1 mark followed by 15 spaces
  • 2/8 (2:6, 2-in-8) – 2 marks in 8 bits (0100 0010…)
  • 3/24, 3-in-24 – 3 marks in 24 bits (0010 0010 0010 0000 0000 0000…)
  • MK – all 1s
  • SP – all 0s
  • 1:1 – alternating 1s and 0s
  • FOX (see ITU recommendation R.52 for definition)

In addition to the standard test patterns the user can supply their own custom test pattern of up to 64Mb, test patterns do not have to be byte aligned.

Test Modes

  • The FarSync BERT Tester can act as either the physical DTE or DCE
  • The tests can be run in loopback or point-to-point modes including interoperation with other suppliers BER Testers
  • Line tests can be invoked manually via the GUI, via batch command files or via the API
  • Tests can be run for a set number of bits or for a defined period of time
