STOP. DO NOT use the vertical position knob to reposition any channel while
doing this check. To do so invalidates the test.
1. Install the test hookup and preset the instrument controls:
a. Initialize the front panel:
H Press save/recall SETUP.
H Press the main-menu button Recall Factory Setup.
H Press the side-menu button OK Confirm Factory Init.
b. Modify the initialized front-panel control settings:
H Do not adjust the vertical position of any channel during this
procedure.
H Set the horizontal SCALE to 500 ps.
H Press SHIFT; then press ACQUIRE MENU.
H Press the main-menu button Mode, and then press the side-menu
button Average 16.
c. Hook up the test-signal source:
H Connect the sine wave output of a sine wave generator to a 50 W
precision coaxial cable followed by a 50 W termination and a
dual-input coupler. (If checking a TDS 794D, substitute a power
divider and two 50 W coaxial cables for the 50 W termination and
dual-input coupler).
H Connect the coupler to both CH 1 and CH 2. See Figure 1–10.
