GMH 041 Product Review Portable Signal Generator $20

This is a product review of a small, portable, low-frequency signal generator that I intend on adding to my instruments case. This unit is nicely packaged and runs on a standard 9-volt battery. For $18.99 it is a good start.

Function (waveform) signal generator. It can produce some special periodic time function waveforms (sine wave, Fang Bo, triangle wave, sawtooth wave and pulse wave, etc.), the frequency range can be from a few micro he to tens of MHz function signal generator in the circuit experiment and equipment detection has a very wide range of uses. So the learning and design circuit will also be used to.

DDS signal generator parameter:

The frequency range of 1HZ-65534Hz is: DDS. (almost no distortion, the enlarged part of the TL082)

High speed (HS) Fang Bo: 1MHZ/2MHZ/4MHZ/8MHZ signal;

The offset amplitude of the DDS signal can be adjusted by two potentiometers;

DDS signal: sine wave, square wave, sawtooth wave, reverse zigzag wave, triangle wave, ECG wave and noise wave.

1602 LCD LCD screen;

Intuitive 5 key keyboards.

Step frequency: 1, 10100100010000Hz;

Automatically recover the last time after the power supply.

Offset: 0.5pp-5Vpp

Amplitude: 0.5Vpp-14Vpp

Output impedance: ohms 20-200
