Onyehn XR2206 High Precision Function Signal Generator DIY Kit

High Precision, can generate sine/triangle/square waveforms. Output frequency range: 1Hz-1MHz and Adjustable frequency and amplitude. Wide power supply range, use 9-12V external power or 9V battery(NOT Included). , Note: no nuts needed on the bottom of the case. The long screws will cut tthreads into the holes on the bottom. Also the nuts for the short screws go between the PCB and the bottom of the case. The long screws hold the top down over the PCB components, holding it altogether. , This is a DIY kit with All are through hole components,easily assemble the Function Generator by yourself. , Sine wave parameters:Amplitude: 0-3V at 9V DC input; Distortion: less than 1% (at 1KHz); Flatness: +0. 05dB 1Hz - 100kHz. , Square wave parameters: Amplitude: 8V (no load) at 9V DC Input; Rise Time: less than 50ns (at 1KHz); Fall Time: less than 30ns (at 1KHz); Symmetry: less than 5% (at 1KHz). , Triangle wave: Amplitude: 0-3V at 9V DC input; Linearity: less than 1% (up to 100 KHz) 10 mA.
