Delay Calibration
When using an oscilloscope for actual measurement, the transmission delay of the
probe cable may bring relatively greater error (zero offset). DS2000 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 set the desired delay time. The range
available is from -100 ns to 100 ns.
Note: this parameter is related to the instrument model and the horizontal time base
currently set. For example, for 200 MHz models, when the horizontal time base is 5
ns, the step of delay time can be set to 0.1 ns; when the horizontal time base is 10 ns,
the step of delay time can be set to 0.2 ns; when the horizontal time base is 5 μs, the
step of delay time can be set to 100 ns; when the horizontal time base is greater than
or equal to 10 μs, the delay calibration is 0 and can not be adjusted.
