Product Description

The DDS generator is small but has many functions, easy to operate, and portable. It can work in the range of 1HZ to 500KHZ. You may choose between an AC/DC adaptor or a lithium battery as your power source.

As well as using it with oscilloscopes, it can also be used to test or debug electronic circuits and analyze the frequency response of audio amplifiers, it also allows the calibration of oscilloscope sweep time factors.

In an oscilloscope attenuator and for adjusting the probe impulse response, the square waveform is used.

You must have a filter (that can be opened and closed) to meet the needs of sine waves and pulse waves.

With this functional signal generator, you will be able to test many kinds of waveforms, such as sine, square and triangle waveforms, positive and negative sawtooth waveforms. A professional worker would benefit especially from it.

Questions & Answers

Provides power via the DC3 connector. A 10V battery. Five vs. Can you please tell me what they are There must be a Dc, are they talking about a range then?

When the voltage is between 3.0 and 5.0, the device will function. A 5 V and a 10 V power supply.

Do you have the capability of creating an audible sound to be amplifed?

Yes, I would say. In this case, 440 hz would be in range of the device. In the middle section of a piano keyboard is that A below middle C. The range of human hearing is well within this range. The best tone can be achieved with a sine wave setting

Is it possible to adjust the output in increments of less than 1Hz?

Each increment is a multiple of 1Hz, with the smallest increment being 1Hz and the largest increment being

The Signal Generator is a great little device for the price

4/5

I like how small it is, how power is supplied by USB, and how easy it is to use. It would have been nice to have a nicer screen and a menu system for choosing the functions and the I can understand the need for simplicity in the case of a low price. In the event that they made $75 or more It would be nice to have a $100 unit with a nicer screen.

It has been taken out of its It is just that I received the signal generator

3/5

I discovered that one of the control knobs was broken when I opened the box As a normal practice, I would return to my last line Although I could go through with it, I think it's not worth it A DATE UPDATED In the end, it turned out that the knob has not only broken and been loose, but also lost contact with the As a result, the whole unit cannot be used A functional word. My time is now wasted on manually processing a return, which is a frustrating experience.

An assembly that is horrific and quality control that is nonexistent It is not usable

3/5

There is no retention nut on the control pot, and it appears that the threaded portion of the pot is too short or the box is too thick There's nothing more to it than spinning and flopping. Likewise, the control knob falls off every now and then. There is no point in using the DC offset indicator The only thing you accomplish by turning it from one extreme to another is to put it in a position that is irrelevant. That would be a good start The service I paid for was not that.

for general ultrasonic audio use, as it will be with a 3D harmonic generator

4/5

This DMM is by 5dig. An audio and ultrasonic SigGen which is handy to carry around. *i>Good I expected everything to work as it should. Up until 999, there was some actual output, albeit quite low. We have exceeded expectations by delivering 999 KHz in sine-wave mode. Within the audio frequency range, all the waveforms are within the I did not have any problems with the DC offset. The filter feature provides marginal added value for what is intended to be used. In the sine wave, there was already good waveform. A few observations In normal practice, DC offset knobs are oriented upside down, so that needed to be fixed. There is about 20 pS of jitter at 100 kHz. Calibration of oscilloscopes can be accomplished using it, but I would not recommend it.

I find it to be surprisingly effective

5/5

Bringing up the rebuild of a power amp was made possible with this. Waveforms can be generated in rectangular, square, or triangle over a range of frequencies much greater than what I need.

A synthesize frequency that is dead on is dead on

5/5

It does not give waveforms as high a quality as However, when it comes to the audio spectrum, it is excellent. You should definitely check it out.

Generates the frequency of sound

3/5

My objective was to reproduce some audio signals for repair, but the signals generated by this instrument were very unpredictable and noisy, so I returned it. Now, I am looking to buy a more expensive but better-quality device.
