The software environment supports four modes: sound card, USB module, serial port capture and virtual simulation. The sound card mode can use the computer's sound card to complete the analysis and processing of signals within the audio range; the USB module can complete the analysis and processing of signals within the bandwidth allowed; the serial port capture can directly capture the data of the serial port and perform the capture The data is analyzed and processed; the simulation mode uses software simulation to realize all functions, which facilitates teaching and theoretical demonstration.
Open software communication protocol, you can add your own hardware to our software environment according to the protocol, and use all analysis functions. The agreement is divided into: learning version and commercial version.
The USB module provides a secondary development kit; it also provides some algorithm libraries in our software to facilitate better secondary development of products.
Function generator:
Supports the generation of "sine wave", "triangular wave", "rectangular wave", "upper sawtooth wave", "lower sawtooth wave", "white noise" and "synthetic waveform", and provides adjustment functions for peak value, frequency and output phase difference .
Wave file generation:
Waveform file output can support "sine wave", "triangular wave", "rectangular wave", "upper sawtooth wave", "lower sawtooth wave", "white noise" and "synthetic waveform", providing peak value, frequency and output phase difference The adjustment function supports output in the form of wav, txt, hex and mif files.
