4. Check Position Range
a.
Set:
VOL TS/DIV (both)
AC-GND-DC (both)
STORE/NON STORE
50 mV
AC
NON STORE (button out)
b.
Set the generator
to
produce a 0.5 V standard-
amplitude signal.
c.
Adjust the
CH
2 VOL TS/DIV Variable control
to
pro-
duce a 4.4 division display. Set the
CH
2 VOL TS/DIV
switch to 10 mV.
d.
CHECK-
The bottom and top
of
the trace may be
positioned above and below the center horizontal graticule
line by rotating the Channel 2 POSITION control fully
clockwise and counterclockwise respectively.
e.
Move the cable from the
CH
2 OR Y input connector
to
the
CH
1 OR X input connector. Set the VERTICAL
MODE switch to
CH
1.
f. Repeat parts c and d using the Channel 1 controls.
g. Disconnect the test equipment from the instrument.
5. Check Acquisition Position Registration
a.
Set:

CONTINUE (button out)
b.
Position the trace exactly on the center horizontal
graticule line using the Channel 1 POSITION control and
position the trace start to the left most vertical graticule
line.
c.
Set STORE/NON STORE switch to STORE (button
in).
d.
CHECK-
Trace remains within 0.5 division
of
the
center horizontal graticule line and the trace start is within
0.5 division
of
the left vertical graticule line.
A-6
e.
Set:
VERTICAL MODE
STORE/NON STORE
CH
2
NON STORE
f.
Repeat parts b through d for Channel 2 trace.
g. Position the trace 0.5 division below the top horizon-
tal graticule line using the Channel 2 POSITION control.
h.
Set SAVE/CONTINUE switch
to
SAVE (button in).
i.
CHECK-
Trace shift
of
0.5 division
or
less.
j. Set SAVE/CONTINUE switch
to
CONTINUE (button
out).
k. Position the trace 0.5 division above the bottom hor-
izontal graticule line using the Channel 2 POSITION con-
trol.
I.
Set SAVE/CONTINUE switch
to
SAVE (button
in).
m.
CHECK-
Trace shift
of
0.5 division
or
less.
n.
Set SAVE/CONTINUE switch
to
CONTINUE (button
out).
o. Set the VERTICAL MODE switch to
CH
1.
p.
Repeat steps g through I for Channel 1 trace.
6.

output via a 50 Q cable, a 1
OX
attenuator, and a 50 Q ter-
mination to the
CH
1
OR
X input connector.
