Delay Calibration
When using an oscilloscope for actual measurements, the transmission delay of the
probe cable may bring greater error (zero offset). The MSO4000/DS4000 allows
users 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 below.
Press CH1 Delay-Cal and use to select the desired delay time. The range
available is from -100 ns to 100 ns.
Note: This parameter is related to the current horizontal time base. For example,
when the horizontal time base is 5 us, the step of the delay time setting is 100 ns.
when the horizontal time base is 1 us, the step of the delay time setting is 20 ns.
when the horizontal time base is 500 ns, the step of the delay time setting is 10 ns.
