High power frequency response analysis
FRA-X
The FRA-X acts as the interface between a ZENNIUM potentiostat and an external potentiostat or an electronic load, enabling EIS measurements outside the power specifications of Zahner products.
Via FRA-X, the ZENNIUM potentiostat modulates the current or voltage output-signal of the external device. The current and voltage input-signals relevant for the EIS measurement are measured directly by the FRA-X with a very high bandwidth, despite galvanic isolation.
The FRA-X opens up new dimensions for EIS measurements on high-performance systems such as single fuel cells with several 100 cm2 or larger fuel cell stacks.
The external potentiostat or electronic load only need to have an analog control input. If the external device can excite sinusoidal signals on its own, the FRA-X can still be used to perform synchronous impedance measurements at individual frequencies.
The measurement setup with FRA-X can also be controlled via our remote interface.
