H Set the output of a DC calibration generator to off or 0 volts.
H Connect the output of a DC calibration generator through a
dual-banana connector followed by a 50 W precision coaxial cable to
one side of a BNC T connector. See Figure 1–23.
H Connect the Sense output of the generator through a second
dual-banana connector followed by a 50 W precision coaxial cable to
the other side of the BNC T connector. Now connect the BNC T
connector to CH 1. See Figure 1–23.

e. Measure amplitude of the probe compensation signal:
H Press SHIFT; then press ACQUIRE MENU. Press the side-menu
button AVERAGE then enter 16 using the keypad or the general
purpose knob.
H Adjust the output of the DC calibration generator until it precisely
overlaps the top (upper) level of the stored probe compensation
signal. (This value will be near 500 mV).
H Record the setting of the DC generator.
H Adjust the output of the DC calibration generator until it precisely
overlaps the base (lower) level of the stored probe compensation
signal. (This value will be near zero volts).
H Record the setting of the DC generator.
f. Press CLEAR MENU to remove the menus from the display. See
Figure 1–24.
