5.2.7 Set DC offset
Press 〖Offset/Low lev〗softkey then set the desired offset value using the knob or numer ic
keypad. Here, enter by knob is strongly recommend because of more convenience feature.
The DC offset setting will limit by amplitude and level, which should be agreed with below
formula:
Limit Low＋ Vpp/2≤Offset≤Limi High－ Vpp/2
If the specified offset is not valid, the waveform generator will automatically adjust it to the
maximum DC voltage allowed with the amplitude specified.
If set amplitude to 0V, high level limit to +10Vdc and low level limit to -10Vdc, then the
offset can be set within ±10V range. T he waveform generator become one set of DC power
supply and can output DC voltage signal.
5.2.8 Set phase
Press 〖 Phase/Align〗 softkey to select 'Phase' then set the desired phase using the numeric
keypad or knob.
Output phase means the phase difference bet ween output signal and synchronous signal,
and output signal advance to synchronous signal.
Press 〖Phase/Align〗softkey to select 'Align' to make the synchronous signal of CHA and
CHB are with same phase. So it's easy to calculate the phase difference of t wo channels on
basis of the phase setting for CHA and CHB.
