TDS5000B Series Specifications and Performance Verification
H To view the stored waveform on screen, verify that the display On
button (in the control window) is toggled to On.
d. Hook up the DC standard source:
H Set the output of a DC calibration generator to off or 0 volts.
H Connect the output of the DC calibration generator, through a
dual-banana connector, followed by a 50 Ω precision coaxial cable,
to one side of a BNC T connector. See Figure 2--26.
H Connect the Sense output of the generator, through a second
dual-banana connector, followed by a 50 Ω precision coaxial cable,
to the other side of the BNC T connector. Connect the BNC T
connector to CH 1. See Figure 2--26.

e. Measure amplitude of the probe compensation signal:
H From the toolbar bar, click Horiz, and select the Acquisition tab.
H Click Average and set the number of averages to 16 using the
keypad or the multipurpose 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 1000 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.)
