Press 1 → More → Ch-Ch Skew, rotate the multifunction knob    or use the 
numeric keypad to set the desired delay calibration time. The available range of the 
delay calibration time is from -100 ns to 100 ns.   
 
Note: This parameter is related to the instrument model and the current horizontal 
time base setting. The larger the horizontal time base is, the larger the setting 
step will be.   
 
 
Offset Cal 
 
When you use an oscilloscope to make actual measurements, a small offset that 
arises from the temperature drift of the component or external environment 
disturbance may occur on the zero-cross voltage of the channel, which will affect the 
measurement results of the vertical parameters. MSO7000/DS7000 allows you to set 
an offset calibration voltage for calibrating the zero point of the corresponding 
channel, so as to improve the accuracy of the measurement results. 
 
Note: If the zero-cross voltage of the channel has a larger amplitude offset that 
exceeds the adjustable null range, please perform self-calibration for the 
instrument to ensure the measurement accuracy. For details, refer to 
descriptions in "Self-calibration". 
 
Press 1 → More → Offset Cal, rotate the multifunction knob    or use the 
numeric keypad to set the offset calibration value.
