Alternate  Display  Switching  Logic

The  Alternate  Display  Switching  Logic  circuitry  controls 

both  the  Nonstore  Horizontal  Amplifier  sweep  switching 
and the  Nonstore Z-Axis  Logic switching for A  Inten and  B 
Only  traces.  The  B  Sweep  ramp  and  gates  are  produced 

for  every  A  Sweep  when  the  HORIZONTAL  MODE  is  set 
to  either  ALT  or  B.  In  ALT,  the  intensified  zone  on  the  A 
Sweep  trace  is  shown  for one  B  Sweep  interval,  and  dur­
ing  the  next  A  Sweep  interval,  a  B  Sweep  trace  is 
displayed  during  the  B  Sweep  interval.  For  B  Only  traces, 

the A Sweep  must  still  run to  produce the  A gating signals 
used  throughout  the  circuitry  for  timing,  but  it  is  not 
displayed.

HORIZONTAL  MODE  switch  S648  selects  the  input 

logic levels  that  drive  the  display  switching  circuitry.  In  the 

A  Horizontal  mode,  the  Set  input  of  U670B  is  LO,  and the 

Reset  input  is  HI.  This  holds  U670B reset  with the A  DISP 
signal  HI,  passing  only  the  A  Sweep  to  the  Horizontal 

Amplifier  (by  the  A  Sweep  selection  transistor,  Q742, 
located  on  Diagram  7).  In  the  B  Horizontal  mode,  the  set 
input of  U670B  is  HI,  and  the  reset  input  is  LO.  This  holds 
U670B  set  with  the  B  DISP  signal  HI,  allowing  only  the  B 
Sweep  to  reach  the  Horizontal  Amplifier  (via  the  B  Sweep 
selection  transistor,  Q732).

With  S648  set  to  ALT,  and  for all  settings  of the VERT- 

ICAL  MODE  switches  except  BOTH-ALT,  the  VALT signal 

applied  to  U660E  is  HI  and  the  Set  and  Reset  inputs  of 
U670B  are  both  LO.  The  LO out of  U660E causes the out­
put  of  U680B  to  be  HI.  Each  HI  to  LO  transition  of  the 

ALT  SYNC  signal  applied  to  pin  1  of  U680A  causes  the 

NAND-gate  output  at  pin  3_to  change  from  LO  to  HI, 

clocking  U670B.  The  Q  and  Q  outputs  of  U670B  therefore 
toggle,  and  the  A  DISP  and  B  DISP  signals  cause  the 
sweep selection  transistors  (Diagram 7) to alternately pass 
the A and  B  Sweep signals to the Horizontal  Amplifier.

When  the  CH  1-BOTH-CH  2  VERTICAL  MODE  switch 

(S550) is  set to  BOTH,  the  ADD-ALT-CHOP  switch (S545) 
becomes  active.  In  the  ALT  VERTICAL  MODE  position, 
the  VALT  signal  is  LO,  the  HALT  signal  is  HI,  and  the 
CH  1  SELECTED  signal  is  a  TTL  square-wave  signal  that 
switches  states  at  the  end  of  the  A  Sweep.  Input  pin 4  of 
U680B  is  HI,  and  the  gate  output  is  the  inverted  CH  1 
SELECTED  signal.  This  output  signal  is combined with the 

ALT  SYNC  signal  by  NAND-gate  U680A  to  clock  U670B. 
Whenever  the  ALT  SYNC  signal  goes  LO  at  the  end  of  a 
sweep  and  the  CH  1  SELECTED  signal  (at  U680B  pin 5) 
switches  from  LO  to  HI,  U670B  is  clocked.  Since  only 
positive  transitions  on  the  clock  input  causes  the  flip-flop 

to  change  output  states,  two  A  Sweeps  must  occur  to 
cause  the  flip-flop  output  levels  to  switch.  Switching  this 
way,  the  crt  first  displays  two  A  Intensified  Sweeps,  then 
two Alternate  B Sweeps.

SWP  SEP.  Whenever  the  B  Sweep  is  selected  to  drive 

the  Horizontal Amplifier, the  Q  output of U670B  is  HI. This 
HI  goes  to  U665C  pin  10  through  Q683  and  Q687,  and 
since  pin  9  is  also  HI, the  SEP signal from  U665C is  LO to 
enable  the  A/B  Sweep  Separation  circuitry  (located  on 
Diagram 3).

B Z-Axis  Logic

The  B  Z-Axis  Logic circuitry switches  signal  current  lev­

els  to drive the  Z-Axis  Amplifier for the  Nonstore  B  Sweep 
and the  A  Intensified  Sweep displays. The  current  supplied 
is  summed  with  the  other  signal  inputs  on  the  Z-DRIVE 
line to set the Nonstore display intensity levels.

With  the  HORIZONTAL  MODE  switch  in  the  ALT  posi­

tion,  pin 5  of  U665B  is  HI.  Then,  the  Q  and  Q  outputs  of 
U670B,  the  B  GATE  signal  from  the  output  of  U665D,  and 
the  B  INTENSITY  potentiometer,  set the  intensity  levels  of 
the  Nonstore  A  Intensified  and  B  Sweep traces.  When  the 
A  Sweep  trace  is  displayed,  the  Q  output  of  U670B  is  HI, 
and  the  Q  output is  LO. These output levels  bias  Q683 on 
and  bias  Q682  off.  The  collector  voltage  of  Q683  reverse 
biases  CR817  to  stop  Z-Axis  drive  current  from  flowing 

through  the  diode.  With  CR683  reverse  biased,  additional 
Z-Axis  drive  current  to  intensify  the  A  Sweep  is  supplied 
whenever  CR685  is  biased  off  by  the  gating  action  of 
U665B.  Since  input  pin 5  of  U665B  is  HI,  the  gate  output 
and  therefore  the  conduction  state  of CR685  is  set  by the 
B  GATE  signal  from  U660C.  While  the  B  GATE  is  HI,  the 

output  of  U665B  is  LO,  and  CR685  is  biased  off  to  add  B 

INTENS  current  to  the  Z-DRIVE  line  via  CR816.  During 

periods  that  the  B GATE is  LO (B  Sweep not  running),  the 
output  of  U665B  is  HI,  and  CR685  is  biased  on.  Diode 
CR816  becomes reverse  biased, and the extra  current  that 
was  being  supplied  to  the  Z-DRIVE  line  to  intensify  the  A 
Sweep is removed.

With  the Q and Q outputs of  U670B switched to display 

the  B  Sweep  (5   LO  and  Q  HI),  Q683  is  biased  off,  and 
Q682  is  biased  on.  The  collector  voltage  of  Q682  reverse 
biases  CR816 to block  any Z-Axis  drive current from  being 
supplied through that diode.  With CR687  off,  the  B  Sweep 
is  displayed  if  CR680  is  reverse  biased.  During  the  B 
Sweep  interval,  the  B GATE  output  at  pin  11  of  U665D  is 
LO.  Diode  CR680  is  then  reverse  biased,  and Z-Axis  drive 

current  from  3  INTENS  flows  through  CR817.  If  the  B 
Sweep  is  not  running,  the  B  GATE output  of  U665D is  HI. 
That  HI  forward  biases  CR680  and reverse  biases  CR817. 
No B Z-AXIS drive current flows through CR817.
