Table 4-7. Playback Controls
Icon Control Description
RECORD Initiates writing data to the open data file; a
TIME STAMP event marker is placed in the
data file indicating the beginning of recording.
PLAY Initiates data playback from an open file
STOP Terminates data recording or playback; the
data file is left open.
PAUSE Stops data playback temporarily; files should
be paused before printing so that the desired
plot is captured for printing.
BEGINNING
OF FILE Rewinds the data file to its beginning; this
only affects data playback. All recording is
done at the end of the data file.
REWIND Backs up the data file during playback to the
previous event marker in the file: automatic
event markers provide periodic events for the
file to be rewound or forwarded to.
CONTINUOUS
PLAY May be enabled during data playback to allow
for continuous play; in continuous play, the
data file automatically rewinds to the
beginning of the file as soon as the end of the
file is reached.
FORWARD Advances the data file during playback to the
next event marker in the file; automatic event
markers provide periodic events for the file to
be rewound or forwarded to.
END OF FILE Advances the data file to its end; this affects
only data playback.
SPEED
CONTROL Adjusts the playback speed; the number
shown is the time in milliseconds (ms)
between waveform samples. The data
sample rate for the Analyzer is 20 ms.
Therefore, a number larger than 20 results in
slower-than-normal playback and smaller
numbers yield a fast playback speed.
