(26) Set oscilloscope calibrator to standby and disconnect equipment setup.
(27) Connect oscilloscope calibrator SOURCE/MEASURE CHAN 1 through a 50Ω
feed through termination to a dual input coupler. Connect open ends of dual input coupler
to TI CH1 OR X and CH2 OR Y inputs.
(28) Set TI CH 1 and CH 2 VOLTS/DIV switches to 20m.
(29) Set oscilloscope calibrator for a CHAN 1, LEVEL SINE mode output of 10 MHz
and amplitude for 6 divisions of deflection on TI crt.
(30) Adjust CH 2 ⇕POSITION control to vertically center trace on center horizontal
graticule line.
(31) Set TI VERTICAL MODE CH 1 BOTH CH 2 switch to CH 1.
(32) Adjust CH 1 ⇕POSITION control to vertically center trace on center horizontal
graticule line.
(33) Position TI controls as listed in (a) through (c) below:
(a) VERTICAL MODE CH 1 BOTH CH 2 switch to BOTH.
(b) VERTICAL MODE ADD ALT CHOP switch to ADD.
(c) INVERT button pressed to IN.
(34) Displayed trace amplitude will be 0.6 divisions or less.
(35) Reduce output to minimum and disconnect equipment setup.
b. Adjustments
(1) Disconnect equipment setup.
(2) Position TI controls as listed in (a) through (o) below:
(a) CH 1 and CH 2 ⇕ POSITION to midrange.
⇦POSITION⇨ to midrange.

VERTICAL MODE CH 1 BOTH CH 2 to CH 1.
(d)
CH 1 and CH 2 VOLTS/DIV switches to 20m.
(e)
CH 1 and CH 2 VOLTS/DIV CAL fully cw to detent.
(f)
CH 2 INVERT pushbutton to out position.
(g)
CH 1 and CH 2 AC GND DC switches to DC.
(h)
HORIZONTAL MODE switch to NO DLY.
(i)
SEC/DIV switch to .5 ms.
(j)
SEC/DIV variable fully cw to detent and pushed in.
