12.2 Polarity
Positive or negative polarity output can be set. With negative polarity output, the device inverts
the data and then outputs it, resulting in a signal that is inverted relative to the offset of the
positive polarity output.
12.3 NoiseSum
You can choose to superimpose random noise on the signal and output it to simulate a realistic
scenario where the signal is contaminated by noise. Click on the settings icon in the "NoiseSum"
parameter setting box to enter the Noise superimposing settings page, where you can
enable the noise superimposing and the signal-to-noise ratio. The signal-to-noise ratio is
measured in ratios (dimensionless) or dB.
Application example: Simulation of a 1 MHz sine wave contaminated by
Gaussian noise with an output amplitude of 1 Vrms with a signal to noise ratio of
20 dB
Note that the requirements of this example are the same as those of the application example in
the section "Waveform Combine". The same effect can be achieved by using a NoiseSum
function in this section.
1. Set "Waveform" of the carrier to "Sine", "Frequency" to 1 MHz, and "Amplitude" to 1
Vrms in the parameter setting page of CH1.
