Vertical
These buttons let you manipulate and vertically position waveforms on a display monitor. The
following table lists the functions of the Vertical buttons and knob.
Button/Knob Function
Vertical Position
Positions the waveform on a display monitor. Use this knob to
move the waveform up or down. Also moves the three parts of a
component waveform separately, depending on the state of the
Position
button and its associated LEDs (
Wfm Pos
for the
AVM-510A).
Position
Selects the corresponding component of a parade filter, waveform,
or S-video waveform (toggles between position 1, 2, 3, or all
three). When used in conjunction with the Vertical Position knob,
allows vertical positioning of each waveform. An LED lights
when a position is selected.
Mag/V Mag
Vertically magnifies a waveform 2.5 times. For the AVM-510A,
the words “Vector Mag” at the side of the
VMag
button indicate
that vectors are also magnified by a 2.5 factor (
Mag
for the AVM-
510A
).
A “VMAG” indicator appears in the waveform and vector
displays to alert you that the display is not normal.
Filter
Used in conjunction with composite signals (although the low
pass Luma filter is available for component signals). Used to
toggle between the luminance filter and chrominance filter or can
be used to parade three waveforms (flat or no filter, luma filter,
and chroma filter). If the display is both a vector and a waveform,
pressing the
Filter button engages the Luma filter on the
waveform so you can see the chroma in the vector (this is the only
filter available in this display mode).
Split Screen
Used to toggle through the following displays:
1. Waveform and vector. Shown in a small window at the
bottom of the picture.
2. Picture Guard (AVM-510A). A picture display that alerts you
to out-of-tolerance elements of the signal.
3. A/Ref Split. Shows the video from the Input A: and the
external reference input in alternating horizontal bands, used
to match two signals without waveform or vector displays.
Refer to Chapter 7, “Viewing Waveforms, Vectors, and Pictures,” for more information
on these types of displays.
