The offset parameter can be set to MINimum, 
MAXimum or DEFault. The default offset is 0 
volts. The offset is limited by the output amplitude 
as shown below. 
|Voffset| < Vmax – Vpp/2 
If the output specified is out of range, the 
maximum offset will be set. 
The offset is also determined by the output 
termination (50Ω or high impedance). If the offset 
has been set and the output termination has 
changed from 50Ω to high impedance, the offset 
will double. Changing the output termination from 
high impedance to 50Ω will half the offset.
