V/DIV.  —  input  divider  switch  —  a  frequency- 

-compensated  divider  connected  in  the 
amplifier  inputs  enabling  calibrated  sen­
sitivity  selection.

Y l  —  input  selector  switch  providing  either 

DC  direct  coupling  or  AC  coupling  via 
blocking  capacitor  or  connection  of  Y l 
input  to  earth.

Y2  —  input  selector  switch  identical  with  Y l.
Yl,  Y2  —  input  sockets  intended  for  the  con­

nection  of  the  voltage  being  measured  or 
of  the  calibrating  voltage.

Y  CAL.  —  continuous  sensitivity  adjustment 

coupled  with  input  dividers.  If  the  sensi­
tivity  of  the  amplifier  is  to  be  calibrated, 
the  potentiometer  must  be  always  turned 
to  the  extreme  right  to  make  the  knob 

index  point  to  the  “Y  CAL.“  sector.

GAIN  ADJ.  —  any  sensitivity  irregularities  o c­

curring  with  the  continuous  sensitivity 

adjustment  potentiometer  in  the  “Y  CAL.“ 
position  can  be  removed  by  means  of this 
element  on  the  side  of  the  instrument.

Horizontal  Amplifier  Control  Elements

The  function  of  the  elements  is  the  same  as  in 
the  case  of  the  vertical  amplifier,  the  only  dif­
ference  being  in  that  the  input  divider  switch 
in  its  extreme  position 

“T. 

B.“  provides  for  the 

internal  connection  of  the  time-base  sawtooth 
voltage  to  the  amplifier.  The  time  base  is  cali­
brated  in  the  extreme  left  position  of  the  con­

tinuous  X-sensitivity  adjustment  potentiometer. 
The  time  expansion  ( 3 X )   is  in  action  in  the 

extreme  right  position  of  this  potentiometer.

Time  Base  Control  Elements

TIME/DIV.  —  time-base  sweep  rate  —  calibra­

ted  stepwise  change  of  the  sweep  rate  at 
a  ratio  of  1 : 2 : 5   within  the  range  off 

from  0.1  sec/div.  to  5,usec/div.

TIME  BASE  (S102)  —  time-base  mode  switch  — 

automatic,  triggered  or  off.

TIME  BASE  (S103]  —  triggering  mode  switch

—  time  base  triggered  by  vertical  ampli­
fier,  from  the  socket  on  face  panel  or  by 
the  mains.

CR  Tube  Control  Elements

BRIGHTNESS  —  brightness  control  of  the  tra ­

ce  on  the  screen.

FOCUS  —  focussing  of  the  trace  on  the  screen. 
GRAT.  —  illumination  of  the  graticule  plate 

over  the  screen.
