Delay Calibration
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 DS2000E, 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 setting step
will be. Take DS2202E 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.
