It also analyzes transistor’s characteristics such as voltage and gain. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. At pin 3 to set the exact medium voltage and the output amplitude. A common function generator provides sine, for example, triangular and square waves.
The 50k pot adjustment is also important. Headphone amplifier x small enough to fit in Altoids tin box, and thanks to low power consumption may be supplied from a single 9V battery.
This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. The output frequency can be modulated by an external voltage using the circuit shown at the right. 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.
Although this is an analogue IC, this project just made it into the Arduino section of my website because it uses an ATmega as a frequency counter and to drive an 8-digit 0.
The output can be buffered to adjust its DC component and signal amplitude. Frequency control The frequency range is controlled with the timing capacitor connected between pins 5 and 6 of the XR and the timing resistors VR1, VR2 and R2 conencted in series between pin 7 and v.
With a pot datassheet 2 megohms and a fixed resistor of 1 ratasheet variation gives a ratio of 1 to and may include a range of 10 Hz to 20 kHz sweep. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings.
XR2206 Function Generator
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. The frequency must be adjustable and at least cover the low frequency range. 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.
Reducing R to 2k gave an ideal 20 ms period, or 50 Hz. Pins 7 and 8 are held at 3 V, and more than 3 mA should not be drawn from them, so 1k is the minimum timing resistor. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors.
Function Generator with XR2206
When pin 9 is below 0. When pin 9 is open or above 2 V, the dafasheet called R1 is used. Many attempts have come out with this simple circuit. The proper adjustment of these controls is necessary for a good-looking sine wave.

The XR has an AM input at pin 1. It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors. The low-cost IC XR provides a very simple function generator with only a few external components.
The XR provides a square wave at an open-collector output, as well as a sine wave. Arduino Prototype uses all standard through-hole components for easy construction, two icc which are hidden underneath IC socket.
The XR makes a quite passable sine wave.
If the applied voltage V is 3. FM would also be good for testing a phase-locked loop.
With the frequency-determining capacitor of 0. The DC bias at this input is necessary, and the signal amplitude must be properly adjusted. 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.
Feed Y and the XR with a triangle wave, and X by the rectified voltage across the tuned circuit. The overlapping of the ranges isn’t ideal but it hasn’t proven to be a problem in practice. The frequency is set by a capacitor, in the range 0. Thus, only a frequency ratio of 1 was chosen toso a finer adjustment is possible. I found 10k and 0. A sine-shaping network makes the triangular signal of the VCO, a sinusoidal signal that can be picked up at the pin 2.
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. The output waveforms can be both amplitude and frequency modulated. In any case, do not exceed 3 mA from pin 7 or 8. Switching frequency ranges from about one switch Verification of a frequency scale Setting the output voltage through a second potentiometer Adjustment to minimize distortion of the sinusoidal signal Setting of the symmetry of the triangular signal 1Hz – 2MHz XR Function Generator Kit.
Use a buffered potentiometer to test the dependence of frequency on VC. The XR offers many possibilities for sine wave generation and modulation over a wide range of frequency. The sample design renounces everything that is not absolutely necessary. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors. The amplitude setting at pin 3 is connected with fixed resistors, so the output voltage is always the same.
All required circuit details are shown in the datasheet. 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.
Frequency can be varied by a range switch and a potentiometer, so that one could make a fairly useful function generator based on this chip, at low cost.
Instead of the sine wave output is obtained after opening of S1 a triangular output wave. One is displaying frequency response on the scope–you might try this with a parallel resonant circuit.
