D. Trigger delay
This feature is useful for user who needs a longer delay time to wait for
the system to be stabilized. The time needed to stabilize a measurement
system is called the “settling time.” The settling time depends on the
measurement range, cable properties and signal source.
Defaults
The default of the trigger delay is automatic. M3510A/11A automatically
selects a delay time for you according to the setting of the measurement
if you do not specify a delay. A list of the default for each measurement
function is shown on
Table 4-5
. The range for the delay is from 0 to
3600 seconds. The defined selection of delay time is stored in a volatile
memory and the default will be restored when the meter is power-off.
The internal settings of automatic trigger delay
The delay time for automatic trigger delay is determined by the selection
of measurement function, range, and the setting of integration time and
AC filter speed. The following table shows the default delay time for each
measurement setting.
