change
the output of the calibration
generator to
5
V.
f.
CHECK—Display

bnc cable and 50 D bnc termination. Set the calibration
generator output for a vertical display of 5 divisions at
1 kHz.
c.
CHECK—Square

than 10%
overshoot
or
rounding.
d. Set A
TRIGGER SOURCE to
EXT/10 and adjust
generator output for
a vertical
display of
5
divisions.
e.
CHECK—Square wave has less
than 10% overshoot
or rounding.
f. Disconnect the
calibration generator high-
amplitude output from
the
A
External Trigger input
connector.
