Signal generator

Signal generator is also known as pitch generator, function generator, arbitrary waveform generator, frequency generator or digital pattern generator. This is an electronic device, which will generate the repeating or the non-repeating electronic signals. These devices will the electronic signals either in analog or in digital domains. Most of these devices are basically used during the testing, designing, troubleshooting, as well as in electroacoustic devices or repairing electronic. They also have the artistic uses. There are numerous types of signal generator available in the market. Most of these devices come out with different applications and purposes. In general, one device cannot be used for doing all the applications. The usage of the device depends upon the application you are planning to do with it. Traditionally, the signal generator have embedded the hardware units. However, from the age of the multimedia-PCs, programmable, flexible software tone generators are also available in the market. The signal generator is also one such device that is used in most of the electronic applications. The accuracy of a signal generator is also very important. Most of the RF signal generators will use the frequency synthesizers, which means that frequency accuracy is also determined by a frequency standard is used within the generator. The frequency standards will have their accuracy distinct with a number of various specifications and these must be combined in the right manner to provide the overall accuracy. All the accuracy measurements will be specified in the form of PPM (parts per million). However, there are also elements including the temperature stability, ageing, line voltage stability. Therefore, before you plan to purchase a signal generator, it is very important to have an idea about the specifications of the signal generators and the actual spec needed. A high performance signal generator will be costly than the ordinary generators.
