Performance Check Procedure— 2230 Service
4. Check Position Range
e. Set:
a. Set:
VOLTS/DIV (both)
AC-GND-DC (both)
STORE/NON STORE
50 mV
AC
NON STORE (button out)
VERTICAL MODE CH 2
STORE/NON STORE NON STORE
f. Repeat parts b through d for Channel 2 trace.
b. Set the generator to produce a 0.5 V standard-
amplitude signal.
g. Position the trace 0.5 division below the top horizon
tal graticule line using the Channel 2 POSITION control.
c. Adjust the CH 2 VOLTS/DIV Variable control to pro- SAVt/CONTINUE switch to SAVE (button in),
duce a 4.4 division display. Set the CH 2 VOLTS/DIV
switch to 10 mV.
i. CHECK—Trace shift of 0.5-division or less.
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.
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.
f. Repeat parts c and d using the Channel 1 controls.
l. Set SAVE/CONTINUE switch to SAVE (button in).
m. CHECK—Trace shift of 0.5 division or less.
g. Disconnect the test equipment from the instrument.
5. Check Acquisition Position Registration
a. Set:
VOLTS/DIV (both)
AC-GND-DC (both)
A SEC/DIV
SAVE/CONTINUE
10 mV
GND
10 ns
CONTINUE (button out)
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.
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).
6. Check Non Store Aberrations
a. Set:
BW LIMIT
VOLTS/DIV (both)
AC-GND-DC (both)
A SEC/DIV
STORE/NON STORE
Off (button out)
2 mV
DC
0.05 fiS
NON STORE (button out)
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.
b. Connect the fast-rise, positive-going square-wave
output via a 50 0 cable, a 10X attenuator, and a 50 ft ter
mination to the CH 1 OR X input connector.
