a. Performance Check
(1) Set DISPLAY MODE switch to CH 1.
(2) Set CH 1 VOLTS/DIV switch as listed in first row of table 11.
(3) Connect oscilloscope calibrator CHAN 1 to TI CH 1 using a 50
feedthrough
fermination and connect oscilloscope calibrator CHAN 2 to TI CH 2 using a 50
t
eedthrough termination.
(4) Set oscilloscope calibrator EDGE output frequency as listed in first row of table 11.
(5) Adjust oscilloscope calibrator output controls for divisions as listed in table 11
for oscilloscope display divisions.
(6) Adjust TI CH 1 POSITION, and TI time base controls to view waveform. If
aberrations exceed limits listed in table 11 perform adjustments as indicated in table 11.
