Delay Calibration
When using the oscilloscope for actual measurement, the transmission delay of the
probe cable may bring relatively larger error (zero point offset). For DS6000, users
can set a delay time to calibrate the zero point offset of the corresponding channel.
Zero point offset is defined as the offset of the crossing of the waveform and trigger
level line relative to the trigger position as shown in the figure below.
Press CH1  Delay-Cal and use the knob to set the desired delay time. The range
is from -100 ns to 100 ns.
Note: this parameter is related to the horizontal time base currently set. For example,
when the horizontal time base is 5 μs, the step of delay time setting is 100 ns; when
the horizontal time base is 1 μs, the step of delay time setting is 20 ns; when the
horizontal time base is 500 ns, the step of delay time setting is 10 ns.
