Preferences
From the Preferences choice, you can enable automatic resizing of windows when
changing standards. This can be useful if you are using the waveform windows at the
default size for a given standard, as not all standards use the same aspect ratio.
When the OmniTek application is started, it automatically loads the configuration that was
active when it was last closed. The second Preference choice here lets the system
prompt you for choice of configuration instead. This can be useful if different people use
the system, and have different requirements.
It should be noted that a System configuration contains 100% of your setup data. It
includes which windows and toolbars are open, and their sizes and positions, what video
format, what locking reference, what options have been set for the optional error logging
package etc.
The ‘Start with Windows’ menu entry forces OmniTek XR to start up at the same time as
you log into Windows. This saves you having to start the application from the desktop, or
Start menu.
There are two menu choices for measurement units. These affect all uses of the related
measurement units. For example, by selecting the amplitude measurement units to be
milli-volts, then amplitude measurements made using the cursors will be in milli-volts, the
minimum and maximum thresholds will be expressed in milli-volts, and all the waveform
graticules will be shown in milli-volts. If the values are expressed as digital levels, this is
as a 10 bit number from 0 to 1023, which can also be shown in hexadecimal.
Similarly the horizontal measurement units can be shown as time, in uS, or as pixel
sample number. Hence the horizontal axis on the waveform graticules will show a
different range of sample number depending on the current video format.
Related to these global settings for measurement units, please note that two separate
waveform calibrations are available. These are the SMPTE range of 64 to 940/960, and
the full range of 0 to 1023. The setting for this can be changed using the Option menu in
the waveform window, selecting the Graticule submenu, and then choosing either
‘SMPTE range’ or ‘Full range’. Full details on the menus in the waveform window are on
page 37.
Windows Layouts, and Snapshots
It is possible to load and save windows layouts. These layouts only save the size and
position, and status of the windows, so engineering settings like video format are
unchanged.
Window snapshots let you save the current contents of a window to a file in an
appropriate format. If all snapshots are saved, then the contents of every open window
is saved. Waveform, histogram and vectorscope windows are saved as bitmap images,
and the dataview window is saved as a text file. It is also possible to save individual
windows, using a menu selection on each window, which is detailed in the Window
menus section, starting on page 37.
