PARADE / OVERLAY. Momentary contact switch that cycles through
selections of sequential displays that can be up to 3 lines or 3 fields on a
single display, depending on the selected waveform sweep.

WFM / WFM + CAL. Momentary contact switch that cycles through
selections of standard waveform or waveform plus calibrator signal for
display on the waveform monitor CRT. Small front-panel light-emitting
diodes indicate the selected display.

8.
INT / EXT / CW. Momentary contact switch that toggles between internal
(from incoming video), external (from rear-panel loop-through input) signals
for sync and subcarrier reference. Pushing and holding this switch selects the
rear-panel CW loop-through as a subcarrier reference. Small front-panel
light-emitting diodes indicate the selected reference.

9.
FLAT / LUM / CHROM. Momentary contact switch that toggles through
Flat (unfiltered video signal), Luminance (chrominance filtered out), and
Chrominance (luminance filtered out) video signal for display. Small
front-panel light-emitting diodes indicate the selected filter.
Flat (unfiltered video signal), Luminance (chrominance filtered out), and
Chrominance (luminance filtered out) video signal for display. Small
front-panel light-emitting diodes indicate the selected filter.
Pushing and holding this button selects a multiple filter display. In 2-line or
2-field sweeps the first half of the waveform monitor display will be flat and
the second half will be the luminance filter. In 3-line or 3-field sweep the
order is flat, luminance filter, and chrominance filter. If the button is held in
during 1-line or 1-field sweep the filter reverts to flat.

10. AUX / LPASS / DIFF. Momentary contact switch that toggles through Aux
Video Input (signal is input following the video filters), low-pass filter
(300 kHz bandwidth) and the Differentiated step (rising and falling
