g. Adjust LEVEL SINE wave frequency until peak-to-peak signal on TI CRT decreases
to 4.2 divisions. Adjust TRIGGER LEVEL control and HORIZONTAL A AND B
SEC/DIV controls as necessary to obtain a stable display. LEVEL SINE frequency will be
150 MHz or greater.
h. Repeat technique of f and g above for settings listed in table 5 below. LEVEL SINE
frequency will be within tolerance listed.
