(19) Disconnect power meter from TI and connect oscilloscope Vertical 1 input to TI
Output.
(20) Set the oscilloscope to measure the pulse width.
(21) Press the Begin key, using the numerical keypad, adjust the displayed Meas'd
Time to match the measured pulse width, then press the ENTER VALUE key. Repeat
this technique for each setup listed in table 19.
