o. Check that the TIME/CM switch is sel to .1 juSEC and
the HORIZONTAL DISPLAY switch is set to X10.
b. Depress the Transient Response Compensation SWIOOO
(see Fig. 5-12o). Check risetime between the
10% and 90% points on the rising portion of the
waveform (see Fig. 5-13). Overall risetime should not
be any slower than 10 nsec.
