Basic Function Generator for Engineering Students

A basic low-cost Signal Generator that is suitable for the learner or engineering student. This DDS can generate Sine, Square, Triangular, Forward and Reverse Sawtooth, Pulse, ECG and Noise waveforms for working with electronic circuits.
The FNIRSI-DDS offers a compact size, complete functions and simple operation with 5 intuitive keys.  It is powered by a 9V DC adapter.  Together with an oscilloscope, it can be used to test and measure electronic circuits for testing and debugging, frequency characteristics of an audio amplifier and impulse response.  Due to the good precision and frequency stability of the FNIRSI-DDS, it is also suitable for the scanning time factor calibration of an oscilloscope.  Square wave output is suitable for oscilloscope attenuator and probe pulse characteristic adjustment.  It also has a filter that can be opened and closed to suit the sine wave and pulse wave output.
Together with the DSO-150 Oscilloscope and the XY-SK80 PSU, you will have a complete test bench at your disposal.  Purchase the complete Student Pack at a discounted price.
