3 3 . S W E E P G A T E O U T
S w e e p gate signal (positive pulse) is available at this
terminal.
3 4 . R E A D G A T E O U T
Positive pulse for one word of final memory address is
available at this terminal.
The signal can be used as a stop signal when a pen
recorder is used.
3 5 . E X T C L O C K
Input terminal for external clock.
C L O C K s w i t c h (1 5) should be set to E X T .
3 6 . Z - A X I S I N P U T
Intensity modulation terminal. Intensity is modulated
at T T L level.
3 7 . S M O O T H E R
W h e n slided this s w i t c h to ON side, the sample
w a v e f o r m becomes joined and makes visible.
3 8 . G N D
Ground terminal. Oscilloscope chassis ground, and
earth ground.
3 9 . M E M O R Y I N P U T
Three input terminals for memorized signals when con-
necting M U - 1 6 5 1 memory unit and using as a mutiple
trace memory oscilloscope.
4 0 . C O N T R O L O U T P U T
Control signal output terminal for memorized signal
w h e n connecting M U - 1 6 5 1 memory unit and using as
a mutiple trace memory oscilloscope.
4 1 . D A T A O U T
Output terminal for memory data (8 bit BINARY) and
timing signal.
4 2 . P O W E R C O N N E C T O R
For connection of accessory power cord.
4 3 . F U S E H O L D E R
For 1 0 0 / 1 2 0 V operation, use a 1.5A fuse. For
2 2 0 / 2 4 0 V operation, be sure to use a 0 . 7 A fuse.
4 4 . P O W E R V O L T A G E S E L E C T O R
Set the selector to the position corresponding to the
correct A C power voltage, 1 0 0 / 1 2 0 / 2 2 0 / 2 4 0 V .
4 5 . C O R D R E E L
Wind the power cord in the reel when the oscilloscope
needs to be transported or it is to be left unused.
4 6 . M E M O R Y ( F O R P E N O U T )
This output terminal is only effective for PEN mode.
When S T A R T (16) is pressed, output of the same data
as that of M E M O R Y O U T P U T ( 2 0 ) starts.
4 7 . R E A D G A T E ( F O R P E N O U T )
This is valid only in PEN mode. This terminal outputs
the same signal as that R E A D G A T E ( 3 4 ) . This output
signal drops to the GND level to start pen operation,
and rises to the H level to stop pen operation when
reading is finished. T h e terminal is grounded in the
S C O P E mode.
