Tutorial Tutorial Figure 2–26: The ERRORS & ALARMS Page of the TRANSMIT Menu Figure 2–26: The ERRORS & ALARMS Page of the TRANSMIT Menu There are two ways to insert errors into the transmitted signal. You can insert errors one at a time or you can set a rate at which the CTS 710 inserts errors automatically. Before inserting errors, you must specify the type of error to be inserted. You specify the type of error to be inserted with the Error type set to parameter.

Appendix F: Example Disk Contents Appendix F: Example Disk Contents This manual ships with a disk containing files that you can load into your CTS 710. The files are examples of instrument setups, test results and pass/fail tests. The files contained on the disk are described in the following paragraphs. Instrument Setups Instrument Setups The STRESS file is an instrument setup file. The file sets up the CTS 710 to generate an STS-1 signal that contains alarms, errors and pointer movements.
Appendix F: Example Disk Contents Appendix F: Example Disk Contents The BER_STS1 file is a 15-minute BER test. The test passes if the BER is better than 10E–7. To run the test, connect an electrical cable between the TRANSMIT and RECEIVE connectors on the front panel and then recall the test from the RECALL PASS/FAIL TESTS page of the TEST SETUPS menu. You can see how the test was set up by viewing the test parameters on the SAVE PASS/FAIL TESTS page of the TEST SETUPS menu after you recall the test.
