External trigger setting
The measurement/computation period is the period defined while the signal applied to
the external trigger input connector is in the specified condition (Hi or Lo).

Selecting the external trigger condition
Select the external trigger condition from the following choices. For the specifications
of the external trigger, see section 7.2, “Selecting the Trigger Source.”
•
The measurement/computation period is set to the period when the external trigger
is in the Lo condition.
•
The measurement/computation period is set to the period when the external trigger
is in the Hi condition.
Re-computing
The measurement/computation period and numerical computation settings can be
changed while the data acquisition is stopped and the numerical data can be re-
computed. All computations including the measurement function data are redone
except for averaging.
Note
•
To improve the accuracy of the measurement and computations, it is recommended that the
measurement/computation period be set as long as possible so that the number of cycles of
the input signal becomes large.
•
When the measurement/computation period is changed, do a re-computation.
