c.
Set the generator to produce a 1 MHz, 5-division
display.
d.
CHECK-Display
aberrations are within 4% (0.2
division
or
less) for the following VOL TS/DIV switch set-
tings: 5 mV through 50 mV. Adjust the generator output
and attach or remove the 1
OX
attenuator as necessary to
maintain a 5-division display at each VOL TS/DIV switch
setting.
e.
CHECK-Display
aberrations are within 6% (0.25
division or less) for the following VOL TS/DIV switch set-
tings:
0.1
V through 0.5
V.
Adjust the generator output
and attach or remove the 1
OX
attenuator as necessary to
maintain a 5-division display at each VOL TS/DIV switch
setting.
f.
Disconnect the cable from the
CH
1
OR
X input con-
nector. Reconnect the 1
OX
attenuator (if previously
removed)
and
reduce the generator amplitude to minimum.
g.
Connect the cable to the
CH
2 OR Y input connec-
tor and set the VERTICAL MODE switch to
CH
2.
h.
Set the generator to produce a 5-division display.
i.
Repeat parts d and e using the Channel 2 controls.
7. Check Store Aberrations
a.
Reconnect the 1
OX
attenuator and 50 n termination
(if previously removed) and reduce the generator amplitude
to minimum.
b.
Set the
CH
2 VOLTS/DIV switch to 2 mV.
c.
Set the generator to produce a 5-division display.
d.
Set:
STORE/NON STORE
SAVE/CONTINUE
STORE (button in)
CONTINUE (button out)
e.
Allow acquisition cycle to complete and press
in
the
SAVE/CONTINUE button to SAVE (button
in).
f.
CHECK-Display
aberrations are within 4% (0.2 divi-
sion or less).

Operators
g.
Repeat part f for each
of
the following VOL TS/DIV
switch settings: 5 mV through 0.5
V.
Adjust the generator
output and attach
or
remove the 1
OX
attenuator as neces-
sary to maintain a 5-division display at each VOL TS/DIV
switch setting.
h.
Disconnect the cable from the
CH
2
OR
Y input con-
nector. Reconnect the 1
OX
attenuator (if previously
removed) and reduce the generator amplitude to minimum.
i.
Connect the cable to the
CH
1
OR
X input connector
and set the VERTICAL MODE switch to
CH
1.
j. Set the generator to produce a 5-division display.
k.
Repeat parts e and f using the Channel 1 controls.
I.
Disconnect the test equipment from the instrument.
8. Check Bandwidth
a.
Set:
VOL TS/DIV (both)
A SEC/DIV
STORE/NON STORE
2 mV
0.2 ms
NON
STORE (button out)
b.
Connect the leveled sine-wave generator output via
a 50 n cable
and
a 50 n termination to the
CH
2 OR Y
input connector.
c.
Set the generator to produce a 50 kHz, 6-division
display.
d.
CHECK-Display
amplitude
is
4.2 divisions or
greater as the generator output frequency is increased up
to the value shown
in
Table A-4 for the corresponding
VOL TS/DIV switch setting.
