® POWER
The power ON/OFF push-switch-. When depressed,
the LED lights up and the machine is in the operating
state.
(2) R F
C H A N N E L
S w i t c h
The channel changing switch used when the
television receiver is receiving patterns from the
pattern generator. The switch selects Channel A
when depressed and Channel B when returned to
the up position, and it can receive all of the
designated patterns.
(D
OUTPUT (RF Signal Output) Terminal
The terminal that outputs the RF signal selected by
the RF CHANNEL switch (#2 above). It has an
output impedance of 75 ohm and an output voltage
of over 10 V rms (when output terminal is open).
® RF O N / O F F Switch
Switch for turning the RF signal ON and OFF. It is
used when the RF signal is not being utilized. When
the switch is depressed, the RF signal is ON.
® SCANNING Switch
Switches between INTERLACE scan and SEQUENTIA
Lscan. The switch selects the sequential (progressive)
scanning mode when depressed, and the interlace
scanning mode when returned to the up position.
When performing adjustment and testing proce-
dures, use the INTERLACE mode for color patterns
and, for monochrome patterns, use the SEQUENTIAL
mode to reduce the occurrence * horizontal flicker.
(D Raster Select Switch
Switch for selecting the raster color. Moving from
left to right, this switch enables selection of red,
blue, green, or white (brightness 100%). The raster
white is represented by white with a brightness level
of 100%. When a black raster is required, turn the
pattern selector to "COLOR" and turn the color
selectors to "CHROMA OFF" and "LUMI O F F . "
(D
S Y N C Switch
Switch for changing the synchronizing signal. When
the switch is depressed, a vertical sync signal is
output via the OUTPUT terminal (#8), and when the
switch is returned to the up position, a horizontal
sync signal is output via the terminal. When
adjusting or repairing color TV receivers using an
oscilloscope, use this switch when you want to
force synchronization along one specific axis
(horizontal or vertical).
(D OUTPUT (Sync. Signal Output) Terminal
Output terminal for the sync signal selected by the
SYNC Switch (#7). The terminal has an output
impedance of 75 ohm and an output voltage of
about 1 V p-p (when output terminal is OPEN).
