Supported Products​

This function requires a high-performance DAQ device equipped with Analog Output (AO):

Product NameDescription
Ethan-O8-channel (+/-10V) analog voltage output

Function Settings​

1. Output Mode (Mode)​

Select the waveform output behavior mode:

ModeDescription
N SampleFinite point output. Automatically stops after generating the specified number of waveform points.
ContinuousContinuous output. The waveform will continue to cycle through output until Stop is pressed.

2. Waveform Type​

The following standard waveforms are supported:

  1. DC Voltage: DC voltage output.
  2. Rectangular: Square wave.
  3. Triangular: Triangle wave.
  4. Sine: Sine wave.

3. Parameter Settings​

Adjust the detailed parameters of the waveform. Please note that the output voltage must comply with the hardware specification limits (+/-10V).

ParameterDescription
Sampling RateSet the sampling rate (maximum supported 10k S/s).
FrequencySet the waveform frequency. Please follow the Nyquist Theorem to set an appropriate sampling rate to avoid distortion.
Amplitude (V)Waveform amplitude (Peak value).
Offset (V)DC offset.
Constraints:
• Offset + Amplitude ≤ +10V
• Offset - Amplitude ≥ -10V
