10.Set the load impedance
Press WaveGen
→
impedance on the frontal panel.
Press impedance softkey to set the load input impedance of the signal generator. It can be
set to "High Z" or "50Ω".
11.Align phase
Press WaveGen
→
Align phase on the frontal panel .
The channels of the signal source will be re-configured after pressing Align phase to
output according to the preset frequency and phase.
For two signals of which the frequencies are the same or are multiples, this operation can
align their phases.
The oscilloscope acquires the waveform of the two channels and displays the waveform
stably. After switching the status of the channel switch, the phase deviation between the
two waveform is changed.
At this point, press AlignPhase softkey and the waveform shown on the oscilloscope will
restore to the phase deviation of the current phase between the two waveform
automatically.
11.1.6.To output DC
1.Select waveform

enable on the frontal panel.
4.Set the offset voltage
Press WaveGen
→
offset on the frontal panel
Note
:When the impedance is High Z, the range is from (-3.5 V + the current amplitude/2)
to(3.5V - the current amplitude/2);when the impedance is set to 50 Ω, the range is from
(-1.75 V + the current amplitude/2) to (1.75 V - the current amplitude/2).
