How to Operate Your Instrument
If the signal appears outside the boundary shown by the blue dashed lines, then the signal is violating the limits that are set.
If alarms have been enabled, then gamut violations will be reported when the signals falls outside the boundaries shown by
the blue lines if the number of pixels in error exceeds the Area threshold.
Arrowhead Menu
The Arrowhead menu enables you to reset the threshold limits to a default setting.
Default Limits: EBU-103 Luma.
Resets the luma thresholds to the values recommended in the EBU R103-2000
specification.
NOTE.
If you need to reset the Y+C limits to their factory default values, you must perform a factory reset. To do this, press
the PRESETS button, touch Settings, touch Recall Preset and select Factory from the Recall menu.
Timing Display
The Timing display is a Tektronix proprietary display that simplifies measuring the timing difference between two signals.
Display Elements:
1. Input Signal Indicator:
A single
1
circle representing timing of input signal
relative to the reference.
2. Reference Indicator:
A cross-hair
indictor centered in the display
represents the reference signal.
3. Vertical Offset
: The timing difference
between the reference and input signal.
4. Horizontal Offset:
The timing difference
between the reference and input signal.
5. Relative to:
Indicates the chosen zero
point for the timing display.

More complex timing relationships display multiple circles. (See page 73,
Timing Displays for Simple Versus Complex Timing
.)

Rear Panel is the default setting, in which offset is shown as zero when the input and reference are at the same timing at the rear panel of the
waveform monitor. If you select
Saved Offset
, you can save the timing from one signal, and then display the timing relative to that saved offset.
