To Set the Delay Calibration

When using an oscilloscope for actual measurements, the transmission delay of the
probe cable may bring 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 actual
trigger position, as shown in the figure below.
MSO4000/DS4000 allows users to set a delay time to calibrate the zero offset of the
corresponding channel.
Press CH1  Delay-Cal and turn the multi-function knob
time (the default is 0.00 s) at certain step. The adjustable range is from -100 ns to
100 ns. Pressing the multi-function knob
0.00 s.
Note: The delay calibration time setting is related to the instrument model and the
current horizontal time base. The larger the horizontal time base is, the larger the
setting step will be. Take MSO4054 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.
