Increase frequency of constant amplitude
signal generator
to
250 kHz. Trace separation shall
be less than 0.1 inches.
5-17. DEFLECTION FACTOR.
5-18. Required Result. The deflection factor of
both the x and y amplifier shall be approximately
100 m V linch (IV p-p for 10 inch deflection) with
front panel gain controls set clockwise. Setting the
gain control counterclockwise increases the deflec-
tion factor by 1.75: 1 (IV p-p for
==
5.6 inch deflection).
5-19. Procedure.
a. Set 50n/l0K switches (on boards Al and A3)
to 10K.
