Zero Point Offset Test
Zero point offset is defined as the offset of the crossing point of the waveform and trigger level line
relative to the trigger position, as shown in the figure below.

Note
[1]
: For different models of oscilloscopes under test, the minimum time base scales are different. For
MSO405X/DS405X, the minimum time base scale is 1 ns/div; for MSO403X/DS403X/MSO402X/DS402X, the minimum
time base scale is 2 ns/div; for MSO401X/DS401X, the minimum time base scale is 5 ns/div.

Test Procedures
1. Connect the active signal terminal of Fluke 9500B to CH1 of the oscilloscope, as shown in the
figure above.
2. Turn on Fluke 9500B and set its impedance to 50 Ω.
3. Output a fast edge signal with 150 ps rise time and 1.2 V amplitude via Fluke 9500B.
4. Configure the oscilloscope:
1) Press CH1 in the vertical control area (VERTICAL) at the front panel to turn on CH1.
2) Press CH1  Probe  Ratio to set the probe attenuation ratio to “1X”.
3) Press CH1  Input to set the input impedance of CH1 to 50 Ω.
4) Rotate VERTICAL SCALE to set the vertical scale to 200 mV/div.
5) Rotate HORIZONTAL SCALE to set the horizontal time base to 1 ns (the setting value is
