(16) Set TI as listed in (a) through (f) below:
(a)
Softkey, EXIT.
(b)
Softkey, Edge.
(c)
Softkey, 150 ps Edge.
(d)
Softkey, LIN.
(e)
Softkey, TARGET 1.
(f)
OUTPUT, ON.
(17) Calculate the adjustment value using the following formula and record in
Adjustment value = TI level(Vp-p) *
TRV = Test reported value for the attenuator placed between
. = 0.1023293
TI and storage oscilloscope.
Example: Adjustment value = 1.0000 *
(18) 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 20 below
and press TI Softkey, ACCEPT CALIB.
(19) Repeat technique of (16)(e) through (18) above for remaining rows in table 20
adjusting the appropriate edge.
