Options Menu

The Options menu allows you to adjust some specifics about how the waveform traces are displayed.

In particular:

Data

For RGB type displays, the components can optionally be re- ordered into the GBR order.

Graticule

The graticule lines can be displayed or hidden, along with graticule text labels. In addition, amplitude markers may be overlaid onto the main graticules. These are horizontal lines that can be used to mark out important levels. It is possible to define multiple markers, and change which is displayed, or to display several at a time. It is also possible to opt for minimal labelling on the various displays.

Note that the units for both axes of the graticules are customizable, using the global selection on the File/Preferences menu selection. For example, this can switch between decimal or hexadecimal values, or into a mV scale. See page 14 for details.

Lastly graticule calibration can be based around the standard SMPTE range of 64 to 940/960 (expressed as decimal, in 10 bit format), or alternatively around the full range of 0 to 1023 (again decimal, 10 bit). Full range video formats are particularly useful when using RGB signals in a Dual Link set-up. For example, Thomson Viper cameras generate RGB in the range 0 to 1023. Other cameras generate RGB in the range 0 to 940. Having the variable calibration means the waveform monitor can be set to suit.

Crosshair

The visibility of the crosshair can be toggled. The crosshair appears as a cursor at a given horizontal position on the waveform. If several components are displayed in the waveform, then the cursor appears in the same place on each component.

The position of the cursor can be changed by clicking within the waveform window.

Look & Feel

The ‘Look and feel’ menu selection opens a dialogue that allows the colours of various items to be customized (shown on the following page).

The colour of the graticule and of each supported waveform element can be individually chosen. In addition ‘error colours’ can be specified uniquely for each different waveform type for use when the waveforms breach the thresholds for valid video (specified in the Engineering Settings control window, as described on page 22). It should however be noted that the areas in error are not always clearly defined when the Interpolator is being used to generate the display (see page 17).

The CRT emulation option applies a special filter to the waveform data to emulate the look that is typical of analog CRT based waveform monitors.

The remaining options allow you to set the crosshair colour and the colour of the measurement cursors, which can be used to measure time or amplitude between two points as described on page 32.
