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.
