Setting Test Control Parameters This section describes how to set the duration for a test, the resolution of the test history, how to start and stop a test, and how to calibrate the instrument for jitter tests. It also lists parameters that cannot be adjusted during a test and other actions that cannot be performed while a test is running. CTS850 SDH/PDH Test Set Setting the Test Time Duration Before running a test, you must specify how long the test will run. The default test duration is continuous, which means a test runs until you stop it with the START/STOP button. NOTE. Most jitter tests run for a fixed duration. You do not need to set test duration for jitter tests.
