Performance Check Procedure
c. Set leveled sine-wave generator output to produce a 7.0 division sine-
wave display amplitude at 500 kHz.
d. Add a 10X and a 2X BNC attenuator before the 50 f l BNC termination
(for a 0.35 division display amplitude).
e. CHECK—that the display cannot be triggered In either HF REJ of
NOISE REJ CPLG.
f. Set:
Horizontal MODE B
A/B SELECT B Trigger
B SEC/DIV 1 |1S
g. CHECK—that the display cannot be triggered in HF REJ or NOISE REJ
CPLG by adjusting the Trigger LEVEL control.

b. Remove the 10X and 2X BNC attenuators from the signal path.
c. Set leveled sine-wave generator output to produce a 7.0 division dis
play amplitude at 25 MHz.
d. Add a 10X and a 2X BNC attenuator before the 50 f l BNC termination.
