h. Change the VERTICAL SENSITIVITY switch to .5 VOLTS/
CM, and adjust the generator output for a 3-cm display.
i. Check— Optimum fla t top on square wave display.
j. Adjust C415B for a level fla t top.
k. Change the SWEEP TIME/CM to .1 mSEC.
l
. Check— Square front corner on waveform, with no
overshoot or rounding exceeding 2% of display amplitude.
m. Adjust C415C for optimum front corner waveform.
A typical display of fast time-constant adjustment is shown
in Fig. 6-17.
n. Change the SWEEP TIME/CM switch to 2 mSEC.
o. Change the VERTICAL SENSITIVITY switch to 5 VOLTS/
CM, and adjust the generator output to maintain a 3-cm
display. (It may be necessary to remove attenuation to
obtain sufficient generator output signal.)
p. Check— Optimum fla t top on square-wave display
as in Fig. 6-16 (B).
q. Adjust C414B to obtain optimum level and fla t top.
r. Change the SWEEP TIME/CM switch to .1 mSEC.
