signal source combines the signal source and oscilloscope,which greatly facilitates the
engineers who need to use both signal source and oscilloscope.The built-in signal source
can output 13 kinds of basic waveform, including sine, square, pulse, triangle,noise,DC,
sinc,exponential,half-distortion, Lorentz, dual tone and multi-frequency, Gauss, Ecg,
meanwhile provides 4 arbitrary waveform.Users can edit,load and output the arbitrary
waveform through WaveEditor software.
This chapter will introduce how to use the oscilloscope built-in signal source.Since the
functions and setting methods of two or three channels signal source are the same, this
chapter takes source 1 as an example to illustrate.
Press/click on WaveGen area on the screen to enter the control menu of the signal
source.
11.1.Output basic waveform
11.1.1.To Output Sine
1.Select waveform
Press WaveGen
→
waveform
→
sine on the frontal panel.
2.Select the data source
Press WaveGen
→
data source on the frontal panel.
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 set the
amplitude of the current signal.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
→
Load impedance on the frontal panel 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 .
