Measurement Mode
The Measurement Mode is an active data-collecting mode, which, for that reason, requires the
use of data acquisition hardware. The Measurement Mode can only be selected if analyzer
hardware is present.
The Measurement Mode acquires data using one of the following three methods:
(1)
Scope-Continuous, (2) Scope-Single, and (3) Record.
The
Scope-Continuous
and
Scope-Single
methods display data, but do not log data. The
scope methods are useful for signal validation and checkout. The
Record
method, in addition
to displaying data, logs data-to-disk based on user-defined start and stop criteria.
In addition to being selected from the Task Menu, the Measurement Mode can be selected
from the Task Tool Bar by clicking the <
Change Task Mode
> button while in the Playback
Mode. Clicking this button from Measurement Mode will change the task mode tool bar to
Playback.
The Measurement Mode is detailed in Chapter 3.

Playback Mode
The Playback Mode does not require the presence of physical hardware. When in Playback,
eZ-Analyst
is strictly a post-acquisition display and analysis program. Raw time-domain data,
that has been recorded-to-disk, can be played back for analysis repeatedly. For example, a
raw signal could be played back several times, each time using a different FFT Window
algorithm to manipulate the original signal. Once the desired results have been achieved the
new data can be exported in a new format and to a different file. The original file can remain
unchanged, and kept for future analysis.
To activate the Playback Mode, select Playback/Review on the Task Menu. An option is to click
the <
Change Task Mode
> button (the first button in the tool bar) while in the Measurement
Mode. If an analyzer (acquisition hardware) is not available
eZ-Analyst
will automatically
enter the Playback
mode and will display the data that was most recently recorded to disk.
The Playback Mode is detailed in Chapter 3.
