(16) Connect oscilloscope calibrator CHAN 1 to TI CH 1 using a 50Ω feedthrough
termination. Ensure oscilloscope calibrator CHAN 1 output is selected by using technique
in step (1) above.
(17) Set DISPLAY MODE switch to CH 1 and CH 1 VOLTS/DIV switch to 10 mV.
(18) Set oscilloscope calibrator VOLTAGE output to 60 mV at 1 kHz.
(19) Adjust CH 1 POSITION and time base controls as necessary to view display.
(20) Rotate oscilloscope calibrator knob located below EDIT FIELD pushbutton to
obtain 6 divisions on oscilloscope display. If displayed waveform does not have flat tops,
perform b(13) below (CH 2, b(14) below).
(21) Remove 50Ω feedthrough termination from oscilloscope calibrator CHAN 1 and
TI CH 1. Reconnect oscilloscope calibrator CHAN 1 to TI CH 1 using a 5-80 pF
standardizer. Rotate oscilloscope calibrator knob located below EDIT FIELD pushbutton
to obtain 6 divisions 6 divisions of vertical display.
(22) Adjust standardizer for optimum square corner and flat top. If standardizer
for SN B160000 and above) to midrange and readjust standardizer for optimum square
wave.
