Frequently asked questions about Frequency generators
01
What is the purpose of a frequency generator?It produces a sinusoidal or modulated signal at a specific, stable and adjustable frequency. It is a reference source used to test the frequency response of a device, power an RF circuit or simulate a clock on a measurement bench.
02
What's the difference between a function generator and an RF generator?The frequency generator focuses on the purity and stability of a sinusoidal signal, often at a fixed or variable frequency but without complex modulation. The RF generator covers a wider range and offers modulations (AM, FM, IQ), while the function generator produces various shapes (square, triangle, pulse).
03
In what contexts are these devices used?In metrology to check frequency responses, in production to power input circuits, in R&D for gain or filtering analysis, or in telecoms for bandwidth and intermodulation tests.
04
What technical criteria should be examined?Frequency range, temperature stability, long-term drift, phase noise level, modulation or synchronisation options, and control interfaces (LAN, USB, GPIB).
05
Is it worth buying a reconditioned frequency generator?Yes, especially for the top-of-the-range models still used in industry. As long as frequency stability and spectral purity are verified, these devices remain reliable for critical applications.

How to choose a reconditioned oscilloscope: 5 criteria that can't be mistaken
A reconditioned oscilloscope allows you to keep a bench operational, avoid manufacturer delays and control a technical budget without losing reliability. It's a useful solution when the aim is to quickly replace a critical device while retaining the same measurement procedures and compatibility with the existing equipment.

How do you choose your Keysight or Teledyne LeCroy oscilloscope for monitoring complex signals?
The two giants of electronic measurement, Keysight (direct heir to HP and Agilent) and Teledyne LeCroy, have occupied a central place in R&D, teaching and metrology laboratories for decades. But while their instruments may seem comparable, their philosophies and strengths differ profoundly. This article will help you to understand their differences...

How to prepare for a COFRAC audit with reconditioned instruments: 6 key steps
A COFRAC audit is not just an administrative control; it is an examination of technical competence and metrological traceability. The use of reconditioned instruments is not an obstacle if each stage of preparation is controlled. With rigorous organisation, a well-monitored reconditioned instrument can be easily integrated into the ISO 17025 standard.
How a CNRS laboratory avoided 4 months of downtime and €91,000 in additional costs thanks to a reconditioned test device
