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 MSO2000A, users can set a delay time to calibrate the zero
offset of the corresponding channel.
Press LA  Delay-Cal and rotate
to set the delay calibration time. The range is
from -100 ns to 100 ns.
Note: This parameter 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 MSO2302A as an example, the step values under different horizontal time bases
are listed in Table 7-1.
