(20) Set TI as listed in (a) through (c) below:
(a) Softkey, GAIN.
(b) Softkey, TARGET 1.
(c) OUTPUT ON.
(21) Calculate the adjustment value using the formula in (17) above and record in
(22) Using the TI arrow keys adjust the TI O/P Amplitude until the storage
oscilloscope amplitude display matches the first adjustment value listed in table 21 below
and press TI Softkey, ACCEPT CALIB.
(23) Repeat technique of (20)(b) through (22) for remaining rows in table 21.

(25) Measure the appropriate edge time listed in table 22 and record as TI measured
value.
(26) Calculate the adjustment value using the following formula and enter in
Edge Time = Measured Time 7.5 ps
(27) Using the TI arrow keys adjust the TI Edge Speed to match the first calculated
adjustment value listed in table 22 below and press TI Softkey, ACCEPT CALIB.
(28) Press the Softkey, NEXT TARGET and repeat technique of (25) through (27)
above for remaining rows in table 22 adjusting the appropriate edge.
