10.Modulation
Press WaveGen
→
Modulation on the frontal panel to enter the modulation setting
interface.For detailed introduction of the modulation function, please refer to the section
"
Modulation
".
Note
:when select the waveform to be ‘‘pulse’’ ‘‘DC’’ or ‘‘noise’’,there is no such setting.
11.Burst
Press WaveGen
→
Burst on the frontal panel.
For detailed introduction of burst function, please refer to the section "
Burst
".
11.1.13.To Output ECG signal
1.Select waveform
Press WaveGen
→
waveform
→
Ecg on the frontal panel.
2.Select the data source
Press WaveGen
→
data source.
3.Turn on/off the channel of signal source
Press WaveGen-
→
enable on the frontal panel.
4.Set the frequency
Press WaveGen
→
frequency on the frontal panel.
Note
: For different waveform, the frequency ranges are different. See oscilloscope
technical specifications for details.
5.Set the amplitude
Press WaveGen
→
amplitude on the frontal panel.
Press amplitude softkey to to set the amplitude of the current signal. For the setting
method, please refer to the section "
Parameter Setting Method
".When the impedance is
set to High Z, the range is from 20 mVpp to 7 Vpp; when the impedance is set to 50 Ω, the
range is from 10 mVpp to 3.5 Vpp.
6.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).
7.Set the phase
Press WaveGen
→
phase on the frontal panel .
The range is from 0°to 360°
8.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".
9.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
