Technical Characteristics

Signal generators have several technical characteristics, including frequency range, amplitude range, and waveform accuracy, which are specified by organizations like Institute of Electrical and Electronics Engineers and International Electrotechnical Commission. The frequency range of a signal generator determines the range of frequencies that can be generated, which is important for applications like wireless communication systems and radar systems, developed by companies like Qualcomm, Ericsson, and Nokia. The amplitude range of a signal generator determines the range of amplitudes that can be generated, which is important for applications like audio testing and vibration testing, as done by engineers at Harman International, Bose Corporation, and Brüel & Kjær. The waveform accuracy of a signal generator determines the accuracy of the generated waveform, which is important for applications like electronic design automation and testing and measurement, used by organizations like Cadence Design Systems, Mentor Graphics, and Synopsys.

Operation and Control

Signal generators are typically operated using a user interface, such as a front panel or a remote control, which is designed by companies like National Instruments, Agilent Technologies, and Rohde & Schwarz. The user interface allows the user to select the desired waveform, frequency, and amplitude, as well as other parameters like duty cycle and phase shift, which are used in applications like pulse-width modulation and phase-locked loops, developed by organizations like Texas Instruments, Analog Devices, and STMicroelectronics. Signal generators can also be controlled using programming languages, such as LabVIEW and MATLAB, which are used by engineers at NASA, European Space Agency, and MIT Lincoln Laboratory. The use of signal generators has been documented in various publications, including IEEE Spectrum, Electronic Design, and Test & Measurement World, which are published by organizations like Institute of Electrical and Electronics Engineers and PennWell Corporation.

Calibration and Maintenance

Signal generators require regular calibration and maintenance to ensure accurate and reliable operation, as specified by organizations like National Institute of Standards and Technology and International Organization for Standardization. Calibration involves adjusting the signal generator to ensure that it is generating the correct waveform, frequency, and amplitude, which is important for applications like electronic design automation and testing and measurement, used by organizations like Cadence Design Systems, Mentor Graphics, and Synopsys. Maintenance involves performing routine tasks, such as cleaning and upgrading the signal generator, to ensure that it continues to operate accurately and reliably, as done by engineers at Hewlett-Packard, Agilent Technologies, and Rohde & Schwarz. The use of signal generators has been documented in various publications, including IEEE Transactions on Instrumentation and Measurement, Journal of Electrical Engineering, and Measurement Science and Technology, which are published by organizations like Institute of Electrical and Electronics Engineers and IOP Publishing.
