1760 Series Component Waveform/Vector Monitor User Manual

Waveform (Multiple)
If
MULTIPLE
is pressed and both
VECTOR
and
WAVEFORM
dis-
plays are selected, menus for all cursor types will be dis-
played. See Figure 3-4. All cursor functions are available in
this mode (the top three bezel buttons are self-cancelling).
Bezel control assignments are the same as for the individual
modes.
Using the Cursors
With Vector Display
To use vector cursors, operate in
VECTOR
or
WAVE-
FORM
mode and press the
CURSOR MENU
button. There are
two vector cursor displays:
POLAR
and
MARK .
(The
VECTOR
PHASE
bezel control continues to adjust the phase of the sig-
nal
.)
Polar Cursors
can be used to measure the amplitude and
phase of the chrominance signal. When
POLAR
is selected,
position the cursor (cross hairs) with the
AMPLITUDE
and
PHASE
bezel controls
,
and view the amplitude and phase
readouts at the top of the screen. See Figure 3-2. When a
component signal is displayed (A 1-2-3 or B 1-2-3), it will be
encoded so that the readout phase and amplitude matches
that of a composite signal. This feature allows the operator
to set component equipment to a specific color phase if the
composite phase value is known.
The cursor zero amplitude point is the center point of the
graticule. Using the amplitude control to move the cursor
out from the center increases the amplitude. Adjusting the
cursor phase will rotate the cursor around the center point,
with the zero phase point being the B--Y (U) axis. The am-
plitude readout can be set for m
V
or
IRE
values through the
CONFIG
menu, described on page 3-20.
