Check
SS
READY
OUT
(REMOTE
ERASE)
a.
Connect
the calibrator signal to the input of the
7A15A.
Obtain
a triggered
display of 2 or
more divisions.
b.
Press
the VAR PERSIST
button.
c. CHECK-That
when the REMOTE ERASE input
connector is
grounded that
an erase cycle is generated.
d.
Repeat
steps b through c
for each storage
mode.
33.
Check EXT
SS
RESET
IN
a.
Set the
7B53A to Single Sweep at a
sweep rate of
0.5 second/division.
b.
CHECK-That when the EXT
SS RESET IN input
is
grounded
that the time-base single sweep function
is reset.
34.
Check
VERT
SIG OUT
a.
Set
the 7B53A to Auto
and adjust the trigger
level
for
a
stable
display at
1 microsecond/division.
b.
Connect a
BNC
cable to the VERT SIG OUT
connector and
to the 7A15A in the right vertical compart
ment. Set TRIG
SOURCE switch
to LEFT VERT.
C. Connect
the 0.4 V CALIBRATOR signal to the input
of
7A15A
in the
left vertical compartment. Set both
vertical amplifiers
for a
deflection factor of 0.2 volts/
division.
d.
CHECK-That a two division signal is
displayed by
the left vertical amplifier.
e.
Set VERT
Mode switch to RIGHT and, check that a
signal
of about
five divisions is displayed
by the right
vertical
amplifier.
f. Interchange the connections
to the vertical amplifiers.
Set the TRIG
SOURCE switch
to right.
g.
CHECK-That a two division
signal is displayed by
the
right vertical amplifier.
h.
Set
the
VERT MODE switch to
LEFT and check that
a signal of about five divisions is displayed.
i. Install
a 50 Ω termination between the cable and the
input
of the
right
vertical amplifier.
j. Set the deflection factor of the
left
vertical to
10 mV/division. Check
for a display of about five divisions.
k.
Disconnect all cables.
35.
Check +SAWTOOTH
OUT
a.
Connect
the
+SAWTOOTH
OUT
to the input of the
left
vertical amplifier. Set
the deflection factor of the left
vertical
amplifier for 2 volts/division.
b.
CHECK—For a sawtooth
display of about five
divisions in amplitude
and greater than 10 cm in length.
