Vector + 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

VECTOR+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.
