Lesson 5 – Waveform Generation with the Mixed-Signal Tool
Floating point format
Waveform Description Parameters
To describe the waveform:
Choose the desired S
1
Enter the number of P
2
You can enter integer or decimal values (for example 0.5).
Check or change the P
3
or gradians.
The waveform is shifted in the negative time direction for positive
values of phase.
Note: If you want to generate an ascending ramp, choose –180
degrees to start with the minimum value.
Decide how you wish to enter the values of A

N (noise lets you add random noise of the maximum amplitude
OISE
as specified in the N
Choices are floating point (default) or integer format, as
indicated in the O
UTPUT
formats can be used. For testing an ADC or buffer, floating point
is recommended.
In floating point format, you define the waveform amplitude,
offset, and noise in fractions of Full Scale (FS), such as 0.333.
The FS of a DAC is defined by its number of input pins—an 8-bit
DAC has an FS of 0 to 255.
The FS voltage of an analog waveform is limited by the capability
of the waveform generator. When downloading the waveform to
an AWG, a reduced FS can be specified.
