Performance Tests
Procedure Steps
Step 1. Check X-Axis Gain
a.
SET:
VOLTS/DIV
(CH
1
and
CH
2)
........ 10 mV
Vertical MODE................................
X-Y
b.
Connect a 50 mV standard amplitude signal from the calibration
generator via a 50 Q
BNC
coaxial cable to
the
CH 1 OR X
input
connector.
c.
CHECK-That
the display is between
4.85
and
5.15
divisions.
d.
Disconnect the test equipment from the instrument.
Step
2.
Check X-Axis Bandwidth
a.
SET:
VOLTS/DIV
(CH
1
and
CH
2)
...
50 mV
b.
Connect the leveled sine-wave generator
output
via a 50 Q
BNC
coaxial cable
and
a 50 Q
BNC
termination to the CH 1 OR X
input
connector.
c.
Set the generator to produce
an
eight-division horizontal
display at an
output
frequency
of
50 kHz.
d.
Increase the generator
output
frequency until the
X-Axis (horizontal) deflection amplitude is 5.7 divisions.
e.
CHECK
-That
the generators frequency is 2 MHz or more.
