About our noise generators ...
In recent years a number of noise generator products have become available from mainly Asian vendors at very attractive prices.
Here is a short list of noise generator features that may help in your selection of the right source for your application:
With our instruments we like to think you very much get what you pay for, professional grade products at reasonable prices!
In recent years a number of noise generator products have become available from mainly Asian vendors at very attractive prices.
Here is a short list of noise generator features that may help in your selection of the right source for your application:
- Flatness and spurious responses. All RFD noise sources are spurious free and most are designed for flatness, or a defined and stable output characteristic. Low cost sources in general are poor in these areas.
- Short term stability. RFD noise semiconductors were selected as part of an 18 month development project in 2001. Whilst a noise generator circuit is very simple, stable operation over temperature and time is not easily achieved. Low cost sources in general use diodes for maximum output, not stability.
- Long term stability. We have built, calibrated and supplied a large number of sources since 2001. We have real time ageing data from life tests. Our noise sources demonstrate much superior characteristics day to day and year to year than low cost sources.
- Output match. Our sources are specified for output VSWR. Low cost sources in general have poorly defined source impedance.
- Component quality. All our products use traceable high quality components, low cost sources in general score very poorly on component quality.
- Life long owner support by email, helping you with your measurements. Low cost sources, probably no support!
