Test Receiver ¸ESPI

Optimized operating concept owing to
decades of experience in EMI test
receiver development

Very high measurement speed

High measurement accuracy

With the two ¸ESPI test receiver
models, the well-known advantages of
the ¸ESIB high-end compliance test
receivers/analyzers have been systemati-
cally 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 equip-
ment.

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.
