With the two ESPI test receiver models, the well-known advantages of the ESIB high-end compliance test receivers/analyzers have been systematically implemented for the upper middle-end.

Due to a common platform system, the user has the additional benefits of the FSP spectrum analyzer family which is already in place. These benefits by far exceed the capabilities and functions of conventional precompliance test equipment.

The ESPI defines the vital criteria, such as functionality, measurement speed and accuracy for middle-end equipment.

The use of innovative techniques, such as the VLSI frontend and largely digital signal processing, together with ASICs developed by Rohde & Schwarz, has resulted in a product with top-class specifications and high reliability.
