understanding signal generator

understanding signal generator

Signal generator is used to check if there is any problem in your electronic appliances. This generator will only be used on the appliances that receive or produce signal, such as radio, and television. This device will check the transmission of the signal. If you have your radio transmission is disturbed or not good, this device will help you to find the problem.

This device is usually used in transmitter or station. They will be checked regularly to control the signal quality so that the radio station or television station will broadcast successfully.

As it is stated on the paragraph above, you will need ac signal generator with a certain frequency of certain amplitude to the input system. You can examine the results that produced in other parts of the system. Electronic things that produce such signals are known as signal generator.

Simple signal generator can produce sine-wave or square wave and ac voltage at certain frequency from 20 to more than 20.000HZ, the output voltage will be various from 10 Vrms drops to zero. Oscillator feedback 360 degrees with Wien-2 component is the common series for this generator. It would provide AC current sine-wave. An amplifier will increase the output.

Sine-wave AC voltage needs to be strengthen if you want to get AC voltage square wave. You should cut the amplitude with a parallel diode. AF signal generator can be used with a series of electronic square wave formation, such as Schmitt trigger circuit to produce a square wave output.

Function generator produces various waves such as sine-wave, square-wave, etc. they are produced in different size, shape and climb voltage or sweeping. Function generator works in low frequency less than 1 Hz till more than 10Mhz. this generator can be a LC oscillator or synthesizer system.
Most of this signal generator is produced to work at 50 or 600. The out put can be adjusted around 10V to 0V.



If you are interested to have a signal generator or want to learn about it, you can check this website square wave generator. If you want to have more complete signal generator, this website is very helpful RF signal generator

RF Synthesized Radio Frequency Signal Generator

RF Synthesized Radio Frequency Signal Generator

Toronto, Canada - GAO Instruments(www.GAOInstruments.com) recommends its synthesized signal radio frequency (RF) generator which can be used in applications such as scientific research, production and general RF testing. On UHF receivers, it can measure selectivity, sensitivity, inter-nodulation distortion, AM rejection, AGC response, audio hum, noise and distortion and STAND ratio. Its flexible step sweep and list sweep functions provide control over output frequency and power.


This synthesized RF signal generator, model A0200001, offers abundant modulation functions including amplitude modulation, frequency modulation, phase modulation and pulse modulation. It works over a wide frequency range of 250kHz to 2GHz at an accuracy of ±0.5dB and from 2GHz to 4GHz of ±0.9dB. The built-in modulation signal generator features a GPIB remote control function, 10MHz frequency resolution, and a wide output power range from -136dBm to 7dBm. When its source power output is less than 4dBm, its spectral purity is less than -30dBc, and when its source power output is less than 7dBm and frequency deviation is more than 3kHz, its spectral purity is less than -53dBc.
