Products: Signal Generators

 
Signal generators are instruments that output repeating or non-repeating AC or pulsed signals. Signal generators usually allow the manipulation of the output signals frequency, amplitude or shape. The circuit architecture that creates the output signals can be generated using either analog or digital circuits.

Term Definition
AM  Amplitude Modulation, often used to broadcast audio signals to consumer radios. 
ARB  Abbreviation for Arbitrary Waveform Generator 
Arbitrary Waveform Generator  A signal generator that can generate waveforms with an arbitrarily defined shape other than the standard Sine, Square or Ramp waveforms found on function generators. 
AWG  Initialism for Arbitrary Waveform Generator 
DC Offset  Settable DC voltage superimposed on the output signal. Used to match the DC voltage at the point of signal injection or for other special applications.. 
DDS  Stands for Direct Digital Synthesis, an implementation technique in newer arbitrary function generators that produces stable and more accurate output, displaying clean sine waves with minimal distortion. Additionally, this technology can minimize the rise and fall times when generating square waves. 
Duty Cycle  Duty cycle is a unit of measure that takes into account the ratio between the width of a pulse signal before a transition and the total time period of one pulse cycle. Pulse width period divided by pulse repetition period. 
FM  Frequency Modulation, often used for broadcasting audio signals to consumer radios. 
FSK  Also known as frequency shift keying, is a type of frequency modulation scheme, primarily used for transmitting information by converting signals into specific frequency and transmitting them over wires. 
Function Generator  A signal generator capable of generating sine, square, and trianlge outputs. 
Gated Tone Burst  Function generator provides output only for the duration of an external pulse. 
Haversine  Half sine wave. 
PM  Also known as phase modulation, is a type of modulation in which the instantaneous phase changes are proportional to the signal to be transmitted. 
Pulse Width  Period of time (usually in micro seconds) that the pulse is high. 
PWM  Pulse width modulation, a type of modulation that takes into account the duty cycle of a signal and modulating it to transmit information. They are often used for controlling analog circuits based on information in digital form. One of the most popular application is a CPU fan inside a computer that changes in speed based on temperature conditions. 
Repetition Rate  Number of times that a pulse recurs in one second. 
RS-232  Recommended Standard 232 serial interface. 
Signal Generator  Any device that generators repeating or non-repeating electronically produced signals. Encompasses function generators, sine wave generators, audio generators, pattern generators, arbitrary waveform generators, arbitrary function generators, rf generators, and DDS generators. 
Sine Wave  Sinusoid wave that is a function with its most basic form is: y = A x sin(wt + p) where A = amplitude, w = radians per second, t = time, p = phase or phase shift. 
Square Wave Symmetry  A measurement of the equity of both halves of a square wave cycle. 
Stability  Amount of amplitude change (Amplitude Stability) or frequency change (Frequency Stability) over a specified period of time after the unit is thoroughly warmed up. 
Sweep Generator  The signal generator output repeatedly sweeps through a band of frequencies usually selectable between linear or logarithmic rate of frequency change. 
Sweep Rate  Rate at which a sweep generator repeats a sweep cycle. 
Sweep Width  The frequency band that the sweep generator covers. Some sweep generators have settable start and stop frequencies. 
THD  Abbreviated as total harmonic distortion, is a measurement of a signal in which indicates the ratio of the total sum of the powers of all harmonic frequencies above its fundamental frequency over the power of the fundamental frequency of the signal. 
Triangle Wave Linearity  A measurement of the slope "straightness" of the triangle waveform generated by a generator. Measured as a percentage where 100% is perfect. 
Triggered Mode  When a signal generator or function generator provides one cycle of the output each time it is externally triggered. It is often used to synchronize the output to an external source.
