    XR2206 Signal Generator Module DIY Kit Sine/Triangle/Square Wave 1Hz-1MHz 9-12V
    Jun 25, 2019
    A good generator for the radioamator.
    The generator covers the entire band from 0.7 Hz to 1.3 MHz, a useful rectangular waveform can be obtained up to 100 kHz, the above is already rounded. The sinusoidal waveform holds level -3dB to some 300 kHz. The disadvantages include: reverse direction of amplitude regulation, wrongly selected precision potentiometer, constant component in sinusoidal and triangular waveforms.

    Good product.
    Both the laser mounting kit and the optics are of good quality. Only the price negotiation option does not make sense, because it does not work anyway.

    Documentation is needed.
    I spent some time looking for a schematic. I found a very similar one. Likewise regarding the instructions, but unsuccessfully. The rest of the time was taken by tests that explained some doubts. I can say that the meter works, but it has some requirements for the input signal - stable and reliable measurement occurs for a 5 V p-p positively polarized rectangular waveform. The messages mean, among others "meter zeroing", switching on / off "energy saving mode". Generally, the meter is functional, but you should attach instructions and diagrams to the KIT.
