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.
Figure 2-1 Zero Offset
Press CH1  Delay-Cal and use to set the desired delay time. The range
available is from -100 ns to 100 ns. Pressing down the multifunction knob will
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.
