(33) Position TI controls as listed in (a) through (d) below:
(a) CH1 AC GND DC switch to DC.
(b) CH 1 VOLTS/DIV switch to 20m.
(c) SEC/DIV to X-Y.
(d) HORIZONTAL MODE NO DLY INTENS DLY'D switch to NO DLY.
(34) Connect oscilloscope calibrator SOURCE/MEASURE CHAN 1 to TI CH 1 OR
X input.
(35) Set oscilloscope calibrator for a CHAN 1, VOLT mode output of 100 mV at 1
kHz.
(36) Rotate oscilloscope calibrator knob located below EDIT FIELD pushbutton until
displayed trace is exactly 5 divisions in length. If oscilloscope calibrator err display is not
within 5.0%, perform b below.
(37) Set oscilloscope calibrator output to minimum and insert a 50 Ω feedthrough
termination into equipment connection.
(38) Set oscilloscope calibrator for a CHAN 1, LEVEL SINE mode output of 50 kHz
and adjust amplitude for exactly 6 divisions of horizontal display on TI crt.
(39) Rotate oscilloscope calibrator knob below EDIT FIELD pushbutton to increase
oscilloscope calibrator frequency until TI crt horizontal display decreases to 4.2 divisions.
(40) Oscilloscope calibrator frequency indication will be ≥ 2 MHz.
(41) Set oscilloscope calibrator output to minimum and disconnect equipment setup.
