The NFA series at one glance
An innovative step forward in the scope of LF analysis: The NFA 1000 is both, a precise 3D magnetic
field logger as well as a high-resolution potential-free E-field „cube“, all in one meter
among the professional devices (patented technology) – supported by the comforting certainty of
having the complete technical expertise of Gigahertz Solutions behind it.
The essence of all devices is a high-capacity processor able to analyse the field situation with an axe-specific FFT and a sampling rate of 110,000 data records per second, and to record all data on a standard SD-card. It is furthermore possible to connect external probes, and to simultaneously record the corresponding measurement values (available for high frequency and for static fields).
The easy to operate PC programme NFAsoft with its revolutionary statistical functions as well as evaluation functions provides a quick overview and – if necessary – an analysis “down to the last detail”.
