Delay Calibration of the Analog Channel
When using an oscilloscope for actual measurement, the transmission delay of the
probe cable may bring relatively greater error (zero offset). Zero 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.
Figure 2-3 Zero Offset
For MSO2000A/DS2000A, users can set a delay time to calibrate the zero offset of
the corresponding channel. Press CH1 Delay-Cal and use to set the desired
delay time. The range available is from -200 ns to 200 ns. Pressing down can
restore the delay time to 0.00 s.
Note: This parameter is related to the instrument model and the current horizontal
time base setting. The larger the horizontal time base is, the larger the scale will be
and the larger the setting step will be. Take MSO2302A as an example, when the
horizontal time base is 50 ns, the step is 1 ns; when the horizontal time base is 2 μs,
the step is 40 ns; when the horizontal time base is greater than or equal to 10 μs, the
delay calibration time cannot be adjusted.
