Displays the time cursor as TIME and the selected numerical value
followed by the unit of measure (µs)
9
Amplitude cursor
readout
Displays the amplitude cursor as AMP and the selected numerical
value, followed by the unit of measure (mV, units, or IRE)
10
Gain
Displays the selected gain; Gain ranges are x0.5 to x15.0

WFM graticule
Shows the WFM RGB, YCbCr, or Composite graticule; the graticule is
dependent upon the Video format, Zoom, and scale selections
Graticules are configured by selecting the Video Input Format along with the appropriate Waveform
Setup scale adjustment (Units, %, or Volts). The scales can also change when the ZOOM button is
pressed.
The following illustrate some waveform graticules with the critical amplitude limits for the video formats
that can be displayed by the CMN-91. The critical amplitude limits are indicated on the screen by special
dashed lines.
