Most engineers are probably familiar with or have come across the decibel or dB as a unit of measurement. Its most common use is in the field of acoustics where it is used to quantify sound levels. However, as will be explained in this article, it is also useful for a wide variety of measurements in other fields such as electronics and communications.
One particular use of dB is to quantify the dynamic range and accuracy of an analogue to digital conversion system. This applies to Prosig’s P8000 range of data acquisition hardware where the noise floor, dynamic range and resolution are all specified in terms of dB. read »»»
The size and shape of the Prosig P8000 data acquisition systems greatly facilitates installation in locations that are small or difficult to access. Now Prosig can offer a new level of flexibility. Not only can the P8000 be used in the laboratory and in the automobile, but with the new mobile Prosig Power units they are truly portable. Now with the new Prosig Power units the systems can operate totally independently. The Prosig Power units can be mounted externally or internally and can provide several hours use. As well as improvements to portability the Prosig Power units can be used in situations where power supply from a vehicle is unstable such as during engine cranking.
The P8000 systems are light and easy to carry. They also offer flexible cable connections. The P8000 has a robust design and is capable of operating under extreme temperatures and harsh conditions. The low power consumption and low heat generation of the P8000 gives its advanced cooling system the flexibility to completely shut off the system fans during data captures thus providing absolute silence for acoustic measurements.
