AVT2767 B

A circuit that allows you to replace the expensive oscilloscope with the adapter connected to a computer with a sound card. A handful of electronic components only has the function of input circuits. The other functions of the oscilloscope are implemented programmatically. The Winscope program is used. It is available on the Internet and has a freeware license. The input circuits are assembled on a small PCB placed in the DB9 connector housing. The circuits are connected to any COM1 / 2 serial port and to the line input of the sound card. After starting the program, the device is ready to work.

The device is particularly recommended in the electronic laboratory, service, research laboratory
