20 Waveform Generator
3 Depending on the selected waveform type, use the remaining controls in the
Waveform Generator dialog box to set the waveform's characteristics.
• X Input — Select between entering the Frequency or Period of the output
waveform. Use the Frequency or Period field to enter the value.
• Y Input — Select between entering Amplitude/Offset or High/Low values to
specify the output waveform's voltage swing. Use the Amplitude and Offset or
Low-Level and high-Level fields to enter the values.
• Logic Presets — Sets the output voltage to TTL, CMOS (5.0V), CMOS (3.3V),
CMOS (2.5V), or ECL compatible Low and High levels.
• Add Noise — Specifies the amount of white noise to add to the waveform
generator output.
Cardiac Use the Frequency/Period, Amplitude, and
Offset fields to set the cardiac signal
parameters.

Gaussian
Pulse
Use the Frequency/Period, Amplitude, and
Offset fields to set the Gaussian pulse signal
parameters.
