Isn't there a digital signal source?

I have never bought any instrument, because I like DIY: I designed a programmable frequency divider (actually composed of a binary comparator and a counter) using a programmable chip, and the output is used as the address line of the RAM memory. The data line of the memory is connected to the D/A converter to output the waveform. The RAM is connected to the microcontroller through a three-state interface to write waveform data. The microcontroller is connected to the PC host computer through a serial port, and the PC draws arbitrary waveforms through the interface and sends them to the microcontroller.

Of course, you can use a desktop computer, a laptop, or a mobile phone to draw the waveform. After drawing the waveform with the mobile phone, send it to the ESP8266 microcontroller via WiFy.
