Nomenclature
1
Input
Displays the user-configurable source IDs for the input and
routers.
2
Format
Displayed as YCBCR, RGB, YRGB, or Composite (CMPST).
This can be selected in the HD FORMAT or SD FORMAT
submenu of the WFM Pane menu.

Change by pressing the STEP or VAR button.
7
Amplitude cursor readout
Displays the amplitude cursor as AMP and the selected
numerical value followed by the unit or measure (mV, units,
or IRE).
8
Time cursor readout
Displays the time cursor as TIME and the selected numerical
value followed by the unit or measure (µS).
9
Line select information
Line select is shown as Line number with the ODD or EVEN

Figure 3-7 to Figure 3-9 illustrates some waveform graticules with the critical
amplitude limits for the video formats that can be displayed by the VTM Series. The
critical amplitude limits are indicated on the screen by special dashed lines.
NOTE: When in VAR mode for all waveform scales, the graticule scale and numeric identifiers will not
be shown. Only the graticule lines will be displayed.
