Circuit  Description—4 8 5 /R 4 8 5  Service

of  U350.  Other  S95  contacts  (shown on schematic 4) close 
to  maintain  the  voltage  at  outer  collectors  pins  5  and  9  of 

U350.  R355,  R356,  and  R357 are low frequency  (thermal) 

transient  response  compensations.  The  CH  2  gain  control 

R358  is  used  to  allow  the  CH  2  gain  control  (front-panel) 

to be centered in its range.

SIG N A L  C H A N N EL  SWITCH

Signal  from  U350 is connected  to pins  13 and  1  of  U430 

and exits  U430 at  pins  16 and  14. The signal  then continues 
on  to and  is terminated  by  the  trigger channel switch  U530, 
diminished  slightly  in  bandwidth  by  the  energy  extracted 

by  U430.

A  push-pull  position  control  signal  is  injected  between 

U430 and  U530 through  R376 and  R386.

If  no  current flows through  Q436, pin  12 is 0.3 V higher 

than  pin  11  and  U430  is  on.  Under  this  condition,  the 
amplified  signal  leaves  pins  5  and  9  on  100 £2  EC  board 
transmission  lines,  joins  with  the  signal  from  channel  1  and 
enters  the  A  Ext  Trigger  relay  K410  on  50 S2  EC  board 
transmission  lines.

Instruments  without  the  A  Ext  Trigger  option  contain 

jumper  wires  in  place  of the relay. The A  Ext Trigger signal 
is  injected  by  the  relay at  this location, which  is considered 
to  be  the  interface  between  the  preamplifier  and  the  main 
vertical  amplifier.  A  RLC  network  consisting  of  C407, 

L409,  R407,  etc.  provides  some  boost  to  compensate  for 

delay line losses at high  frequencies.

The  signal  next  passes  into  the  delay  line  DL410  which 

delays  the  vertical  signal  75 ns  so  that  the  sweep may start 
before  presentation of the triggering signal.

IN T E R N A L   TR IG G E R   A M P LIFIE R

Signals  looped  through  U430 continue  to trigger channel 

switch  U530  and  are  terminated  in  R528  and  R529  which 
are  the  collector  loads  for  U350.  If  no  current  flows  in 
Q538,  voltage  divider  R534  and  R535  holds  pin  12  of 

U530  above  pin  11  and  the  CH  2 trigger signal amplified  in 
U530  appears  between  pins  5  and  9  of  U530.  Trigger 

channel  switch  U530  is  turned  off  when  Q538  conducts 
4 mA,  pulling  pin  12  down  to  9.8 V  (0.3 V  below pin  11). 
Signal  current  in  this  case  is  shorted out  by  the connection 

between  pins  6  and  8.  In  either  case,  the  total  current  in 
U530  is  unchanged  so  that  the  voltage  on  pins  5  and  9  of 
U510 remains unchanged at +12 V.

Q544  and  Q546  provide  small  additional  gain  for  the 

trigger  signal.  RT551  temperature  compensates  the  gain  of

stages  U310  through  Q564.  Q552  and  Q556  select  the 

bandwidth  of the trigger signal.

In  the  full  bandwidth  mode  Q556  is on  and  Q552 is off. 

Filter  L559,  R559,  R557,  and  C557  provides  a  constant 

impedance  at  all  frequencies  as  the  collector  load  of  Q556 
and  thus  full  bandwidth.  In  the  20  MHz  mode  Q552 is on, 
Q556  is  off,  and  high  frequencies  are  attenuated  by  C557. 
Since  the  bandwidth  filter  in  the  vertical  amplifier  is  a 
two-pole  filter,  the  3 dB  point  of  the  trigger's  single  pole 
filter  is  slightly  less  than  20  MHz. The low frequency  phase 
shift  of  the  two  filters  is  identical,  however,  so  that  phase 
match  may occur  in  X-Y operation  of the scope.

Signals  at  the  collector  of  Q556  are  buffered  by  emitter 

follower  Q564  and  sent  to  A  and  B  trigger  amplifiers  via 
J568  and  J566  respectively.  CR562  matches  the  base 
emitter  junction  of  Q564,  and  R560 is adjusted so that the 
zero  signal  voltage  at  Q564's  emitter  is  zero.  R562  pulls 
away  the collector current of  Q556 or Q552.

Q572  and  Q576  buffer the  trigger signal,  which  becomes 

the  X  signal  in  X-Y  mode.  C572  is  part  of  the  filter which 

matches the delay  of the vertical  delay line  DL410.

Trace Separation

Trace  separation  circuitry  injects  a  positioning  signal  at 

the  main  vertical  interface  during  the operation of  B sweep 
in the  ALTernate sweep  mode.

Q440,  Q456,  Q444,  and  Q454  provide  the  push-pull 

trace  separation  signal  through  R440  and  R456.  R458 and 
C458  ensure  that  the  output  impedance  of  the  trace 
separation circuitry  is  100 f l  at all frequencies.

M A IN   V E R T IC A L   A M P L IF IE R

The  signal  received  from  delay  line  DL410  is terminated 

and  T coil  peaked  by  the  inductance  of  pins  1,  13,  14, and 

16  of  U620.  The  required  additional  inductance  L621  and 
L625  is  achieved  in  the  leads  to  pins  16  and  14  which  are 

lengths  of  run  on  the  etched circuit  board. This  inductance 
plus  C621  and  C625,  made  from  3  layers  of  etched circuit 
board,  and  R621  and  R625  form  the  forward  termination 
of  the  delay  line.  The  same  method  of  termination  and 
peaking  is  used  in  each  stage using the  151-0078 integrated 

circuit.3  The  network  attached  to  pins  2  and  3  of  U620, 

provides  delay  line  and  thermal  transient  response compen­

sation. The gain of the main vertical  amplifier  is adjusted by 

R629.  Vertical  amplifier  gain  is  temperature-compensated 

by  RT644.
