Lock Waveform Graticule
A lock is associated with the graticule that overlays the
waveform. Where this lock is set, applying horizontal and
vertical offsets (as described under ‘Display Properties’
below) moves the waveform but does not move the
graticule. When the lock is not set, the whole pattern
(waveform + graticule) can be shifted left or right, up or
down the screen by applying horizontal and vertical offsets.
Whether the graticule is locked is set on the
System page of
the Config window.
Amplitude Measurement Units
The units in which the signal amplitude axis is measured is
set by the
Amplitude Measurement Units setting on the
System page of the Config window.
Composite Matrix
Different matrices may be applied in producing the
composite waveform display. The OTR can either be set to
select the appropriate matrix automatically, based on the
input video standard or it can be set to select a particular
composite matrix. The selection is made through the
Composite Matrix Type option offered on the Video
Config page of the Config window.
Display Properties
Other aspects of the Waveform View are determined by the
tile’s properties, a complete read-out of which is given in the
Properties control (Control Panel: press PROPS to display).
Shortcuts to several settings are provided through the Button
Bar (Control Panel: press GENERAL or OTHER;
Mouse/Keyboard: click on tile to display).
Scaling and Offset
H Mag and V Gain define the horizontal and vertical
scaling applied to the waveform. The options in the
Properties control are associated with a range of values (
H
Mag : x1, x2, x5, x10, ROI; V Gain : x1, x2, x5, x10).
Selecting the H Mag / V Gain option offered in the Button
Bar switches between 1x and the last of the other scalings
to have been selected.
H Offset and V Offset define the offset of the waveform
displayed from the time and voltage axes. These offsets may
also be adjusted by turning the HORIZ and VERT knobs
(respectively), while pushing either knob returns the
corresponding control to its default position.
Note: The
HORIZ and VERT knobs cannot be used to adjust these
offsets when cursors are displayed (see below) because then
the role of these knobs is to move the cursors. Note also that
if the waveform graticule is unlocked (see Configuration
Issues above), adjusting the offset simply shifts the whole
pattern up or down, left or right.
