left side view.
(23) Adjust oscilloscope calibrator output for 6 divisions of display at each
VOLTS/DIV switch setting listed in
table 10. If
oscilloscope does not
display square
corners and flat tops, perform appropriate adjustments listed in table 10.
(24) Remove 5-80 pF standardizer from oscilloscope calibrator CHAN 1 and TI CH 1.
(25) Set DISPLAY MODE switch to CH 2, and repeat technique of (16) through (23)
above for CH 2.
(26) Ensure oscilloscope calibrator CHAN 2 is connected to TI CH 2 using a 50Ω
feedthrough termination. Ensure oscilloscope calibrator CHAN 2 output is selected by
using technique in step (1) above.
(27) Set DISPLAY MODE switch to CH 2 and CH 2 VOLTS/DIV switch to 10 mV.
(28) Set oscilloscope calibrator to VOLTAGE, and output a 60 mV, 1 kHz output.
(29) Adjust CH 2 POSITION and time base controls as necessary to view display.
(30) Rotate oscilloscope calibrator knob located below EDIT FIELD pushbutton to
