(7) Storage oscilloscope mean display will indicate within the storage oscilloscope
limits of table 23. If not, perform b below.
(8) The difference between the measured value and the TI displayed value will be
within TI Display limits listed in table 23. If not, perform b below.
(9) Repeat technique of (4)(j) through (4)(n) and (6) through (8) above for remaining

NOTE
Ensure the 9500B rear-panel CAL ENABLE/DISABLE switch
is in the ENABLE position and return to original position
when complete.
(1) Connect TI output to the storage oscilloscope input.
(2) Connect TI CH5 output to storage oscilloscope trigger input.
(3) Set storage oscilloscope to measure edge and amplitude V p-p with full
(4) Set TI as listed in (a) through (h) below:
(a)
MODE.
(b)
Softkey, CALIB.
Enter Password (exp. 2→3→5→7 ).
