2.6.2 Signal add-on

DC Offset

This function allows the operator to switch in a dc offset. The maximum voltage is 1000mV. 
In the condition of setting DC offset  to  300mV,  the DC offset  is sourced from an internal 

“super  capacitor”  which  at  least

3  minutes  of  accurate  and  stable  300mVdc  offset  to  be 

placed  in  series  with  the  main  waveform,  without  impacting  the  quality  of  that  main 
waveform.
