Digital Channel Delay Calibration
When using the oscilloscope for actual measurement, the transmission delay of the
probe cable may cause relatively larger error (zero offset). Zero offset is defined as
the offset of the crossing point of the waveform and threshold level line relative to
the trigger position. For MSO1000Z, users can set a delay time to calibrate the zero
offset of the corresponding channel.
Press Delay-Cal and rotate to set the delay calibration time. The range is from
-100 ns to 100 ns.
Note: The delay calibration 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 MSO1104Z as an example; the steps under different
horizontal time bases are as shown in the table below.

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