Product Description

A low frequency low power function generator, the FG-100 DDS Function Generator has numerous features.

Despite its small size, it has a full range of functions, and is highly You can use either an AC/DC adapter or a lithium battery as its power source.

By using an oscilloscope, it can be used for troubleshooting electronic circuits and characterizing the frequency response of audio amplifiers or measuring the impulse response of audio systems.

It can also be used to calibrate the sweep time factor of oscilloscopes due to the accuracy and frequency stability of the DSS. In addition to calibrating an oscilloscope attenuator or adjusting a probe, its square wave can also be used as a calibration source

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

Questions & Answers

Do you have the option of setting the duty cycle to whatever you like? Could it be compared to a saw tooth with a 90% duty ?

The answer is no. You could use a simple square wave or a sawtooth wave as well. A duty cycle of 50% is used.

As part of the title, you will find the terms "frequency counter". The main reason I bought it was for that reason. When doing a frequency counter, how do you access it?

The same model belongs to me as well. A marketing skill is able to use a reference in a frequency counter. As it claims to be a "Signal Source," it is ideally suited for frequency counters. The trick is to make you think it can also be a frequency counter, but it isn't. A frequency counter must be verified to make sure it is working. It is unfortunate that you have to learn this This is not something that is affordable like other Frequency counters are.

When you install a battery, how do you do ?

The use of batteries is not recommended. You may encounter some obstacles and have normal use interfered with if this product has to be disassembled when installing batteries.

Does this signal generator allow you to plug in a portable speaker?

The answer is yes. Connectors are necessary if you want to use this method. Using the BNC plug and Stero plug I had to buy, I needed to buy a BNC connector. There are two screw connectors in each. I charged the battery and connected some wire to the speaker. Once I did that, it drove

The price you pay is the quality you get

3/5

I like how easy it is to use and how good it looks. Unfortunately, the frequency readings for sine waves were off. The generator needed to be run at 49Hz in order to monitor 40Hz. A considerable amount of "lumpiness" was also evident in the output. In terms of voltage output, the sine wave output is quite ragged on the positive going side. When fed to an amp and speaker, the output is distinctly Since I have used the function generator boards where this is likely based, it may be that the sine wave linearity is not set appropriately. Just be aware, there is no point in troubleshooting.

You can get it for $30, and it's perfect for people who don't have much money Applications that are critical! The interface is very interesting! I don't think it's too great but it's an interesting workaround to getting a rotary encoder that costs a lot more

4/5

There is a 1ppt It was purchased for speedo repair so that I could synthesize the output from a vehicle speed sensor. In the absence of In critical applications like this, the product is excellent value for Level output with a good linearity and a consistent output level. The slew rate is about what you would expect from Amazon, and it appears in the images as well. Considering the price of 30 dollars I find that to be a fair price!.

I think it works

3/5

An adapter with a male to male BNC connector and a 5v power supply are needed to connect to the Mini DSO. There is a special USB pin on this device as I had to use an old power supply and splice and connect the male USB plug supplied to it. In the instructions it is stated that the Lithium battery will operate as if there is a battery adapter inside the unit The fact is that there are There is no obvious issue with the patterns. My Mini DSO and I used this to practice. As I could not get any response from the "AMP", "DC Offset" or "Filter" adjustments, I am not sure what they did.

This is what I found to be effective Everything described here is true

5/5

For my test of electronic tachometers, I needed a signal generator. I can generate pulse trains with any desired RPM using this method. I was able to do it at minimal cost. This is dead-on accurate when it comes to If it had an output cable, such as a BNC to alligator clip, and a conventional USB power cable rather than one with an oddball connector, then it would be great. A usb portable charger served as power so that an AC adapter did not cause noise or ground loop problems.

It is a good value for the price, but it comes with some compromises It was an excellent deal considering what I bought it for

4/5

I'll use it to test speakers that were repaired. I didn't notice any high frequency noise in my tests, but others may notice some. Low frequency settings do show some high frequency noise in the output. Power supply suggestions or instructions are not provided, nor is there any power supply included. It worked fine with a regular 5v USB power supply (phone charger), but I am not sure if it was the high frequency noise. In any case, it's a decent deal for the price.

The software does what it says, is relatively easy to use, and is well worth the price

5/5

Despite only having a quick glance at the output of the signal generator on a scope, I can clearly see that its frequency and waveform parameters match or exceed its specifications, and the generator is easier to control than I expected. Nonetheless, the device should serve a number of applications, such as audio generation, very low RF frequency generation, circuit testing and prototyping, etc. I powered it via the USB power cable that's included, but this might be unreliable in some instances. My grandkids received it as a gift. The price is right, and the instrument is decent.

I am not accurate and the app is difficult As one example, the device was supposed to reach a Vpp of 10V, but when I hooked it up to my power supply, the voltage was much lower A scope was used to test it, and it maxed out at microvolts

3/5

I think there was a setting that fixed it, but it did not come with instructions or was not intuitive, so I never figured out how to do it and Google didn't have My original F-card got replaced with a different one after I sent it back Several years ago, I purchased a gen for $20 more that was more accurate and simpler.

The Signal Generator is a An inexpensive addition to the home electronic hobbyist, Signal Generator is not bad

4/5

However let me state that it is not something I would deem suitable for any professional application, but I think it is pretty cool, and the waveforms it produces are It's pretty nice to view sine, triangle, square, and sawtooth on an oscilloscope, when viewed with relatively good resolution, you will see a nice and clean wave. While the 5V maximum may limit some, as an educator, it serves my I think the maximum frequency of 900,000 Hz is pretty good, but I was thinking that perhaps it could go even.
