Performance  Check  Procedure
9.  Delay Time  Position  Range
a.  Set time-mark generator for 0.1  ms.
b.  Set:
A SEC/DIV  1  ms
B  SEC/DIV  5  jis
K- OR DELAY control  ?0.000 ms
c.  CHECK—that the Intensified dot Is positioned  at  or before  the second
time marker.
d.  Turn the |«- or  DELAY  control  clockwise until the  delay readout  stops 
Increasing  (largest  number).
e.  CHECK—that the Intensified dot Is positioned at or  after the 99th time 
marker  (located at a  Delay  Time of 9.9 ms).
f.  Disconnect the time mark generator from the  2245A.
10.  X-A x is  Gain  Accuracy
a.  Set:
X-Y
CH  2  (CH  1  off)
10 mV 
DC 
GND
Horizontal  MODE 
VERTICAL MODE 
CH  1  and  CH 2 
VOLTS/DIV 
CH  1  Input  COUPLING 
CH 2  Input COUPLING
b.  Connect calibration generator Std Ampl output to the CH  1  input via a 
50 f l  precision  BNC coaxial  cable.
c.  Set  calibration generator for Std Ampl  output,  50  mV.
d.  CHECK—X-Axis  amplitude  is  between  4.85  and  5.15  horizontal  divi
sions.
e.  Disconnect  calibration  generator.
