Features:
Small size, complete functions, simple operation, easy to carry. It can be powered by a power adapter or a 3.7V lithium battery.
Combined with oscilloscope, it can be used for electronic circuit test and debugging, frequency characteristic and impulse response test and measurement of audio amplifier. Because DDS has good accuracy and frequency stability, it is also very suitable for oscilloscope scanning time factor calibration.
The square wave output is suitable for oscilloscope attenuator and probe pulse characteristic adjustment.
Has a filter (can be opened and closed) to adapt to the sine wave and pulse wave output.
The functional signal generator can detect a variety of waveforms, such as: sine wave, square wave, triangular wave, positive sawtooth wave, anti-sawtooth wave and so on
DC4-9V power supply is recommended when using adapters, and 3.7V lithium batteries are recommended when using battery power. Current :180MA, voltage 5V
Frequency range: sine wave 0.01Hz-500.00 kHz(with the further increase of frequency, the output amplitude will decrease), other waveforms 0.01Hz-100.00 khz(but does not limit the upper limit of adjustable frequency, if the distortion and jitter requirements are not high, the use of frequency can be further increased).
Analysis :0.01 Hz. Sine-wave distortion: less than 1kHz
MODE: The mode key is used to change the output waveform.
Cursor: Used to move the cursor (adjust the frequency using the +- key).
RUN/STOP: runs or stops the waveform output.
When the cursor does not blink, output waveform, other keys are invalid.
+: Frequency +, -: frequency -
DCOFFSET: indicates the DC bias switch
Adjust the DC component of the signal by adjusting the yellow knob ON. Ejected to OFF, the DC component of the signal is 0.
FILTER: Filter switch, when the signal is close to more than 300K sine wave, press this button, the waveform will be clean. But the amplitude of the signal will also be smaller
AMP: Side keys adjust signal amplitude (clockwise amplitude increases)
Package Included:
1 * signal generator
1 * USB power cable
1 * BNC clip
1 * double-ended BNC cable

I needed this to calibrate my Stewart-Warner balancer. The 20Hz 5V RMS signal was perfect according to my oscilloscope. The gain on the amp is a little touchy but no real problem.Nice smooth sine wave at 20Hz. 5V RMS is around 14V peak to peak and it had no issue doing this at basically no load. I left it running for over an hour and it didn't drift at all. Some people have reported trouble with the power connector but I moved the device around a lot and had no issues with disconnects.I really like how simple it is to use.
