Set the waveform parameters
The waveform parameters of AWG are shown in the table below. The setting method refers to
that of a sine wave.
Table 9-5 Description of AWG waveform parameters
AWG
Sample rate /
Frequency
Sample rate / Frequency of the signal. The unit of sample rate is Sa/s,
which refers to the clock rate of the waveform. The unit of frequency is
Hz. The relationship between the two is:
Sample rate = Frequency x number of waveform points
Amplitude/High
level
Offset/Low level
Same as the sine wave
Interpolation
Interpolation mode. Refer to Table 9-6 for the details
Table 9-6 Interpolation modes supported by AWG
Interpolation
Explanation
0-order hold
Zero-order hold
Linear
Linear interpolation
Sinc
Sinx/x interpolation
Sinc27
Sinx/x interpolation combined with low-pass filter，bandwidth = 0.27 x
sample rate
Sinc13
Interpolation combined with low-pass filter, bandwidth = 0.13 x sample
rate
9.5.3 Data Source
Click the setting icon in the "Source" parameter setting box to enter the data source selection
page. Data sources include Built-In, From File, and EasyWaveX. Click the data source type area
in the "Source" parameter setting box, and then select the data source in the pop-up list.
Built-In Waveform
The built-in waveforms are a series preset waveforms in the signal generator. There are a few
types: Common, Math, Engineering, Window, Trigo, Square, Medical electronics, Modulation,
Filter and Demo. Under each type, there are a variety of waveforms to choose.
Click the value area of the "Wave Type" parameter setting box, and then select the waveform
from the waveform list on the right. When a page cannot be displayed all the waveforms, a scroll
bar will appear on the right side of the list. Scroll the bar up and down to view the entire list.
