Chapter 2 To Set the Vertical System RIGOL
MSO2000A/DS2000A User’s Guide 2-9
For MSO2000A/DS2000A, users can set a delay time to calibrate the zero offset of
the corresponding channel. Press CH1 ïƒ Delay-Cal and use to set the desired
delay time. The range available is from -200 ns to 200 ns. Pressing down can
restore the delay time to 0.00 s.
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 scale will be
and the larger the setting step will be.
Take MSO2302A as an example, the step
values under different horizontal time bases are listed in Tab le 2-2.
