EXFO PM-1600 High-Speed Power Meter - Manual (Page 55)

High-Speed Power Meter 45
6 Programming Acquisitions
Programming Data Acquisitions
In addition to measurement mode (where power measurements are
constantly updated on the display) and to manually stored power
measurements, the PM-1600 allows either timed or triggered programmed
acquisitions. Here, absolute or relative power measurements are acquired
for a fixed number of samples, thus for a fixed duration at a specific
sampling rate and stored in the PM-1600’s RAM.
With programmed acquisitions, it is possible to use the same sampling
rates as the ones defined in the Setup menu (i.e., from 1/4 Hz to 256 Hz), as
well as higher sampling rates (from 512 Hz to 4096 Hz). Both types of
available sampling rates are displayed in the following table.
.
A manual range (see Setting Measurement Range on page 22) must be set,
on both channels when using a PM-1620, to perform a programmed
acquisition.
The sampling rate defined in the Program menu is independent of the
sampling rate defined in the Setup menu.
The two types of programmed acquisitions (timed acquisition and
triggered acquisition) are described hereafter.
