a. Hook up test-signal source 1 (See Figure 4--39):
H Connect the sine wave output of the sine-wave generator through a
50 Ω precision coaxial cable to CH 1 through an adapter.
H Set the sine-wave generator to output a 1.5625 GHz sine wave.
b. Initialize the instrument: Press the DE FAULT SETUP button.
c. Modify the initialized front-panel control settings:
H Press the Vertical SCALE to 50 mV per division.
H Set the horizontal SCALE to 200 ps per division.
H From the button bar, touch the Disp (display) button.
