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). MSO1000Z/DS1000Z
supports user to set a delay time to calibrate the zero offset of the corresponding
channel. 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.
Press CH1  Delay-Cal and use
available is from -100 ns to 100 ns. Pressing down the multifunction knob
reset 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 MSO1104Z-S as an example. The step values under different horizontal
time base are as shown in the table below.

Note:
When the horizontal time base is equal to or greater than 10μs, the delay
calibration time cannot be adjusted.
