Bowtie
In BOWTIE mode, the display is forced to a two line or field
sweep and A123 input is selected. The left half of the dis-
play shows CH-1 minus CH-2 and the right half shows CH-1
minus CH-3. If the timing between channels is matched, the
centers of the bowties will be centered and not skewed. If
CH-2 is delayed with respect to CH-1, the skew moves to the
right. If CH-2 is advanced with respect to CH-1, the skew
moves to the left.
NOTE
A123 (or B123) must be configured as a compo-
nent input. See
CONFIGURE menu, page 3-20.
Picture
The PICTURE mode allows the operator to verify the signal
source. In PICTURE mode with LINE SELECT on, a bright-up
marker identifies the selected line in the picture.
Time Code
Longitudinal time code is monitored in a frame-rate display
to allow observation of amplitude, synchronization, and
phase with respect to reference vertical sync. Synchroniza-
tion is confirmed by the stationary display and time code
phase is determined by horizontal position of the time code
sync word on the CRT.
Multiple
When MULTIPLE is pushed, WAVEFORM , VECTOR , and SCH
(Option SC only) can be selected at the same time.
When exiting MULTIPLE , the instrument will return to the
previous (non- MULTIPLE ) DISPLAY settings. When entering
MULTIPLE again, the previous MULTIPLE display settings will
be restored.
