Spectrogram Configuration - Promax TV EXPLORER HD User Manual

5.16.2.1 Spectrogram Configuration

Before the capture begins the options must be configured. Press the key,
[17] and an option menu will be displayed.
Temporal reference
Begin:
The captured information will be showed on the display with initial reference 0 s.
In this option the screen is not updated with news acquisitions unless the cursor
is moved at the end of the capture.
Using the temporal position, the cursor can be move through the entire file and
the display will be updated according to the new temporal reference.
This option is very useful to visualize the captured information. For example if
the elapsed time is 500 sg and we want to show the 200 s, this number must be
filled in the temporal position. The cursor will be moved to, and the screen will be
updated showing the new levels signals.
End:
Selecting this option, the cursor is related to the last acquisition time. If the
temporal reference is filled with 0 seconds, the cursor will be placed at the end of
the capture, therefore the screen always shows the last acquired data.
This option is very useful if we want to work during the capture process due to
the problems can be detected in real time and the cursor can be moved at any
temporal reference. When a temporal movement is introduced, noticed that a
negative sing is placed before the number by default. This is due to the
displayed data on the screen is captured in real time so that if we want to
analyze a previous point we should go backward in the time. For example if the
elapsed time is 500 s and we want to go to the second 200, the temporal
t
position must be filled with — 300 s.
Save
Introduce a name to save the file. If the name already exists a message will be
showed and the file could be overwritten or the operation canceled.
