(5) Repeat technique of (4) above for TI switch settings and adjustments listed in
table 6. At
each setting, adjust for optimum square-wave display on
oscilloscope crt.
b. Adjustments. No further adjustments can be made.

25. High Frequency Compensation and Rise Time
a. Performance Check
(1) Position TI controls as listed in (a) through (c) below;
(a) MODE switch to CH1.
(b) CH1 and CH2 AC-DC-GND switches to DC.
(c) CH1 and CH2 VOLTS/DIV switches to 1.
(3) Adjust time base plug-in (A8) control for two cycles of square-wave display on
oscilloscope crt. If optimum square wave is not displayed, perform b below.
(4) Measure rise time, using standard rise time technique. Rise time will be 35
nanoseconds or less.
(5) Set TI MODE switch to CH2 and repeat technique of (2) through (4) above for
channel 2.
b. Adjustments. Adjust
(L361) and
(L371) (fig. 1) for square-wave display with no
overshoot (R).
