Zero Point Offset Test
Zero point offset is defined as the offset of the crossing point of the waveform and the trigger level
relative to the trigger position as shown in the figure below.
Specification:
Zero Point Offset 500 ps
Test Devices: Fluke 9500B
Test Procedures:
1) Connect the active head of Fluke 9500B to CH1 of the oscilloscope, as shown in the figure
below.
2) Output a fast edge signal with 150 ps rise time and 600 mV amplitude from Fluke 9500B.
3) Configure the oscilloscope:
a) Press CH1 in the vertical control area (VERTICAL) at the front panel to enable CH1.
b) Rotate VERTICAL SCALE to set the vertical scale to 100 mV/div.
c) Rotate HORIZONTAL SCALE
to set the horizontal time base to 2 ns (for DS2102
and DS2072, set the horizontal time base to 5 ns).
d) Rotate TRIGGER LEVEL
to adjust the trigger level to the middle of the screen.
e) Rotate VERTICAL POSITION
and HORIZONTAL POSITION
to set the
vertical position and horizontal position to appropriate values respectively.
4) Observe the display of the oscilloscope. Press Cursor  Mode “Manual” to enable the
manual cursor function to measure the zero point offset and record the measurement
result.
