How to Operate Your Instrument
To choose the pair of inputs that is displayed in the Phase display, select
Phase Pair
and select which meter bar pair you
want displayed in the Phase display. If you select
Bars Flexible Pair
for the Phase Pair, you can use the
FlexPhase Ch A
and
FlexPhase B
soft keys to specify any combination of meter bars to be displayed in the Phase display.
Lightning Display
Pressing the
MAIN
button calls up the Main pop-up menu. From the Main pop-up menu, you can select the
Lightning
display under the
Measure
heading. The Lightning display is a measurement method that allows for the evaluation of the
luma signal gain and for making chroma/luma gain comparisons. It can also provide simple indication of inter-channel
timing errors indicated by a bowing in the trace between the green-magenta transition. The display is created by plotting
luminance versus B-Y in the upper half of the display and inverted luminance versus R-Y in the lower half of the display. The
bright dot in the center of the screen is the luminance blanking level. The points above and below this show the plots of
the different color components based on their signal amplitude. The Lightning display requires a color bar test signal be
used. However, since most programs have leaders of color bars for setup, you can use the Lightning display to check a
program during the leader section.
