Functional Overview
WFM 601A, WFM 601E & WFM 601M User Manual
2–3
nance signals. The top of the display plots Y against P
b
while the bottom plots Y
against P
r
.
GAMUT. Displays the video signal in Diamond or Arrowhead gamut displays.
Diamond mode evaluates RGB signals for gamut limit violations. Arrowhead
display plots Y versus chrominance magnitude to show adherence to composite
gamut limits. A gamut error message appears at the lower-left when an RGB or
Composite gamut error is detected. Turn this alarm on or off in the CONFIG
menu.
WAVEFORM. Displays the video signal as voltage versus time. Any or all of the
three channels can be displayed from a single video line.
PARADE. Displays up to three channels of the serial video signal in succession.
MULTIPLE. Allows two display modes to be active at the same time. The
Waveform or Parade can be displayed with either Vector, Lightning, or Diamond.
PICTURE. Displays the video signal source. When Line Select is on, the selected
line is highlighted to identify where it is in the video picture.
BOWTIE. Displays a bowtie test signal to determine timing differences between
the three component signals, Y, P
b
, and P
r
. The external video source must
generate a Bowtie test signal.
DGTL WFM. (WFM 601M only) Displays the displays digital word values as a
waveform. The data values are not interpolated to generate the waveform.
DGTL LIST. (WFM 601M only) Displays the sequential data values in a list. Data
may be in linear data sequence or as groups of four values as they appear in the
multiplexed data stream: C
B
, Y, C
R
, Y’.
Displays the stereo analog audio input as a Lissajous pattern. The size of the
opening in the pattern is relative to the phase error between the X and Y audio
channels. The Lissajous pattern will take one of three general forms: a line, an
ellipse, or a circle.
