Section 4 OPERATING INSTRUCTIONS

4.3.5 Offset voltage setting range

Fig. 4.3.5-1 Offset Reference Value and Amplitude Change

Note: Since the offset-voltage upper and lower limit values are limited by V

(-2.0 V ≦ V

≦ +2.0 V), when V

or V

are set, the amplitude is limited at a certain value and may not change further.

Example: If V

is set at +1.00 V offset voltage and if there is a signal with amplitude 0.5 Vp-p added, that amplitude

can only be increased to 1.0 Vp-p.

This is because their superposition after the increase would be meeting the maximum allowable level +2.00 V.

Figures 4.3.5-2 to 4.3.5-4 show the relationships between amplitude and offset-voltage settable ranges at three offset

references.
