ENAReport  Offline data postprocessing
ENAReport is a handy tool for analysis, displaying, comparison, export and protocol generation of data stored by the ENA power quality analyzer. Data can be analyzed in time domain, frequency domain, statistical analysis and special analysis according to EN50160 are possible. Protocols from the measurements can be printed or saved to BMP or HTML. Also it is possible to export the measured data into ASCII files. Thanks to clientserver technology data can be processed locally or remotely.
