V-Scope Controls
V-Scope commands appear in red directly above the front panel buttons. They are valid when the selected unit
is a V-Scope, as determined by the DIP Switch settings outlined in the installation section of this manual.
WAVFRM
Places the V-Scope in FULL SCREEN WAVEFORM DISPLAY mode.
VECTOR
Places the V-Scope in FULL SCREEN VECTOR DISPLAY SCOPE mode.
OVRLAY
Places the V-Scope in FULL SCREEN WAVEFORM + VECTOR SCOPE OVERLAY mode. This produces a display
with both full screen waveform monitor and full screen vector scope simultaneously displayed.
SPLIT
Places the V-Scope in WAVEFORM AND VECTOR SCOPE SCREEN mode. This produces a display in which the
top half of the screen shows live video and the bottom half consists of quarter-sized waveform monitor and vector
scope displays placed side by side.
NRM
Places the V-Scope in the NORMAL DISPLAY mode. The V-Scope display is updated every two frames.
SUPER
Enables the superimpose output from the V-Scope, which contains the synthesized waveform/vector display as
determined by the other selections (i.e., waveform, vector mode).
PK/VAR
Selects between PEAK-HOLD and VARIABLE DISPLAY modes. When PEAK-HOLD is selected, old data is not
erased. A cumulative display showing all peak video excursions results. When VARIABLE is selected, rotate the shaft
encoder to select a display rate and change the display update rate. Increasing the rate produces a more fully colored
display.
FREEZE
Freezes the V-Scope trace, providing an instantaneous snap shot of the current waveform/vectors display.
1H/ 2H
Selects between 1-H (single video line) and 2-H (dual video line) display modes. 1-H mode provides the best display
resolution. Use the 2-H mode to view the horizontal blanking interval of the video signal.
LOW
Sets the V-Scope in the low pass frequency response mode. This is normally used when setting white or black levels
while viewing the V-Scope waveform monitor display.
FLAT
Sets the V-Scope in the flat frequency response mode.
Note: The NORMAL display command is sent to the V-Scope upon selection of any of the above modes except
FREEZE, PEAK HOLD, and VARIABLE modes.
