To Set the DC offset 

 

The following steps describe how to change offset to 1 Vdc. 

 
1. Press the Offset/LowLevel softkey 

The  displayed  offset  is  either  the  power-on  value  or  the  offset  previously 
selected.  When  changing  the  function,  the  same  offset  is  used  if  the  current 
value  is  valid  for  the  new  waveform.  To  set  the  LowLevel  for  the  waveform, 
press the softkey again to switch to the LowLevel parameter.

 

 
2. Input the desired offset

 

Use the digital keypad to input the value directly, enter the value “

1

”. 

 

 
Then press the corresponding softkey to select the desired unit. For example, 
press 

Vdc.
