Solartron announce the next major breakthrough in multi-channel impedance
measurement performance. The modular 145x series FRAs (1455 frequency range
10μHz to 1MHz, 1451 frequency range 10μHz to 100kHz) utilize the latest
signal processing devices to provide amazing high-speed impedance
measurements while maintaining the accuracy, repeatability and resolution of
previous Solartron frequency response analyzers.
Solartron’s reputation for the design and manufacture of top quality AC
measurement instrumentation is built upon the performance of its range of
frequency response analyzers (FRAs). Solartron started as a company in the
1950s, initially supplying frequency response test instrumentation into
critical, high accuracy aerospace applications. Over the years, the company
has diversified into many other applications areas including battery, fuel
cell, materials and electrochemical test, but the basic philosophy for
producing high quality, accurate and reliable test instrumentation has
always remained the same.
This technical note explains why Solartron impedance analysis systems are
the reference standard worldwide and by comparison with more limited systems
explores some of the reasons why the new product range will be the standard
by which all others are judged.
