Read times. Hi, I would like to own function generator for the hobby and I don't know anything about what should I look for in function generators when buying them I see gen. The following users thanked this post: Doogs.
NZ Siglent Distributor. Excuse me saying this but if you have no idea what to look for, do you really need one? If you do need one you must have an idea what you want to use it for and then you have a starting point: "Can it do what I want to use it for?
The 7 Best Function Generator kits in 2020 Reviews & Buying Guide
The approach I took was to decide what sort of frequency range I might want to go up to in my electronics and then I kitted my lab out gradually with appropriate kit. Apart from bandwidth you need to decide whether or not you're bothered by jitter, whether you want low phase noise at audio frequencies, if you will want more than one channel and whether you might want to play back long arbitrary waveforms or perhaps have short pulses spaced by large intervals which can be problematic for some signal generators.
Do you want to have modulation and different wave shapes square, triangular, arbitrary as well as sine? Even if you decide to buy a more fancy generator later on it will stay handy to have around.

Tom45 Frequent Contributor Posts: Country:. The frequency range is important, both maximum and minimum frequency. Also think about whether you might need two output channels or just one. And what maximum output voltage would you want. I was about to buy a Rigol function generator until I realized that its 10 volt maximum output was only for channel 1.
Maximum for channel 2 was only 3 volts. For me, the reason why I like it so much is that it has a very cool user interface. I do a lot of work with superimposed sine waves Re price; I lucked out and got mine for bucks.
The case cant be opened due to dents and the NVRAM is fucked, but I stuck in a floppy for waveform storage between sessions and am a happy camper for now. Re the Chinese: never had one. But I never bought Chinese for large instruments I would not buy a SigLent. Feel like some additional tamile wisdom? Smith Frequent Contributor Posts: Country:.Welcome, Guest.

If it turns out you need more features and end up buying a more expensive generator at some point in the future then the Feeltech generator is still useful to have around.

This application note describes the design, construction and the performance of such a complete function generator system suitable for laboratory usage or hobbyist applications.
The entire function generator is comprised of a single XR monolithic IC and a limited number of passive circuit components. It provides the engineer, student, or hobbyist with highly versatile laboratory instrument for waveform generation at a very small fraction of the cost of conventional function generators available today.
All Rights Reserved. The basic circuit configuration and the external components necessary for the high-quality XR function generator system is shown in Figure 1. For most applications, split-supply operation is preferred since it results in an output DC level which is nearly at ground potential. The circuit configuration of Figure 1 provides three basic waveforms: sine, triangle and square wave.
There are four overlapping frequency ranges which give an overall frequency range of 1 Hz to kHz. In each range, the frequency may be varied over a tuning range. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings.
The output waveforms can be both amplitude and frequency modulated. Function Generator using XR The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. It is a very useful bench test equipment for testing and finding out the frequency of various devices with unknown frequency such as oscillators, radio receivers, transmitters, function generators, crystals, etc.
It can be connected to any type of stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground.
It also analyzes transistor's characteristics such as voltage and gain. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors. Headphone amplifier is small enough to fit in Altoids tin box, and thanks to low power consumption may be supplied from a single 9V battery. It's small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors.
Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket.
You can control lights, fans, AC system, computer, printer, amplifier, robots, garage door, security systems, motor-driven curtains, motorized window blinds, door locks, sprinklers, motorized projection screens and anything else you can think of.Model animation—bringing models to life—adds enormously to the interest and enjoyment of any layout or individual model! What enables the close coordination of all of these is an Arduino based DCC generator combined with the general purpose capabilities of Arduino control.
This article describes the newest version I use, based on a low cost add-on or daughter board that attaches to an Arduino Pro Mini. These boards are included for the modeler too. This pair can be configured in a large number ways, and like the decoders, a pre-configured set of options is described and made available for the modeler to load into their own Pro Mini.
Then, you are good to go. Absolute stopping blocks can be used as safety or guard block to prevent your fine locos careening into the abyss beyond lift-uts and open bridges on your layout. The combination can also be used as a general purpose interface board for an Arduino Pro Mini, to ease interface tasks, or directly drive 2 DC motors or a stepper motor.
Normally, I do not use it for manual control, even though I will show how it can operate as a basic substitute, perhaps for a display or test track. I started with this design because I built animated scenes that used commercial DCC decoders, and had the need to control other lights, motors, and sounds in addition.
I do wish to make it clear this is, and was, never meant to be used as a substitute for a complete DCC command station. In my view it has utility and value beyond that. One might think that such a little board serves one purpose and should be built one way.
Well … no! You can certainly build it with all components and use it to drive its own DCC bus. You can also use it as a Pro Mini bread board or prototyping aide, a single or dual motor driver, a stepper motor driver, a DCC Function Generator and a single DC motor driver. Connect the appropriate blobs before attaching the Pro Mini board. It will be easier that way. I always include them.
The daughter board or driver board can be soldered or socketed to the Pro Mini controller.
There is provision for an on-board, 5 Volt regulator. A0-A3 designate those pins that can also be used for Analog inputs like for use with a resistive potentiometer as a speed controller. The board combination is small enough to hide in an HO scale model structure, building, or scene.
