What is the specification of function generator?
Specifications. Typical specifications for a general-purpose function generator are: Produces sine, square, triangular, sawtooth (ramp), and pulse output. Arbitrary waveform generators can produce waves of any shape.
What is the function of function generator?
A function generator is a piece of electronic test instrument used to generate and deliver standard waveforms, typically sine and square waves, to a device under test. It can be used to test a design or confirm that a piece of electronic equipment is working as intended.
What are basic parts of function generator?
The block diagram of function generator contains various components they are frequency control network, constant current supply source 1, constant current supply source 2, integrator, voltage comparator multivibrator, capacitor, a resistance diode shaping circuit, and two output amplifiers.
What is the frequency range of function generator?
Typically function generators are only able to operate at relatively low frequencies, some only operating to frequencies of around 100kHz, although more costly test instruments can operate at higher frequencies, up to 20 or 30MHz.
What is function generator block diagram?
Function Generator Working & Block Diagram Function Generator Block Diagram. The block diagram of a function generator is given in the figure. In this instrument, the frequency is controlled by varying the magnitude of the current that drives the integrator.
What is duty cycle in function generator?
Duty cycle: This control on the function generator changes the ratio of high voltage to low voltage time in a square wave signal, i.e. changing the waveform from a square wave with a 1:1 duty cycle to a pulse waveform, or a triangular waveform with equal rise and fall times to a sawtooth.
How many types of function a function generator can generate?
Many function generators are also capable of generating two different waveforms simultaneously (from different output terminals, of course). This can be a useful feature when two generated signals are required for a particular application.
What is symmetry in function generator?
The function generator has a symmetry function to control the rise and fall times of sine or sawtooth waves and the duty cycles of square waves. It also has a sweep function that makes the output signal traverse a range of frequencies.
