(5) Set oscilloscope calibrator LEVSINE output to produce a 120 mV at 50 kHz and
adjusting edit amplitude output dial for 6 vertical divisions on TI.
(6) Set oscilloscope calibrator frequency output to produce 80 MHz.
(7) Using oscilloscope calibrator, increase frequency edit dial until frequency drops
the amplitude down to 4.2 divisions on TI. If frequency is not greater than or equal to 100
MHz, perform b below.
(8) Set oscilloscope calibrator to standby.
