Broadband noise generator suitable for calibration of test sites/shielded enclosures. It is a self-contained unit with replaceable dry cells. The device creates “white” noise over the spectrum. Included in the kit is the LSA-01 LISN adaptor (9kHz-30MHz); TLM-01 top loaded monopole (30MHz-1GHz) and a MON-02 (1-2GHz) monopole. From new the unit was calibrated at the Y.E.S. test site on a 10 metre range. This will enable the end user to compare their site measurement data against an approved site.
