Selecting the Sampling Type

Selecting the Sampling Type
You can perform different types of samplings with your power meter:
Continuous sampling signifies that power measurements are
constantly updated on the measurement display for an unlimited time
period. You can select a rate that will optimize instrument flexibility
and measurement stability as well as determine the quantity of data
generated during data acquisition.
Single sampling signifies that power measurements will be taken
once, at the rate you have selected. This type of acquisition is
particularly useful when using a high acquisition rate, since the higher
the rate, the more data is transmitted. It will be easier for your power
meter module to manage one huge input of points as opposed to
several at the same time (it will stop analyzing if overwhelmed by
data).
User Defined sampling signifies that you can enter the rate and the
time units you wish to use. The value you enter in the 1/ list is the
number of time units the acquisition process will use. For example, if
you enter a value of 10, and select seconds as the unit, an acquisition
will be performed once every ten seconds; if you enter a value of 1 and
select seconds as the unit, an acquisition will occur every second, etc.
