Test Period: Represents the period of time used to calculate the SDT
measurement. Choices are 6 μs to 5 minutes. Unit choices are μs, ms,
s, and min. The default setting is 5 minutes.
On/Off button: Press On/Off to enable/disable the disruption time
measurements. However, the measurement will only start if the test is
already started, or when the test will be started.
Note: Stopping the SDT test will stop the measurement without clearing the
results. The SDT test is automatically stopped without clearing results when
the test is stopped. However, starting the test again while the STD is still On
(enabled) will reset the results before restarting.
