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 MSO1000Z, users can set a delay time to calibrate the zero
offset of the corresponding channel.
Press Delay-Cal and rotate to set the delay calibration time. The range is from
-100 ns to 100 ns.
Note: The delay calibration setting 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 MSO1104Z as an example. When the horizontal time base is
200 ns, the delay calibration setting step is 4 ns, namely -100 ns, -96.0 ns, -92.0
ns……100 ns; when the horizontal time base is 2.00 us, the delay calibration setting
step is 20 ns, namely -100 ns, -80.0 ns, -60.0 ns……100 ns.
