HP 8591EM EMC Analyzer, 9 kHz to 1.8 GHz

[ Summary ][ Features ][ Specifications ][ Key Literature ][ Ordering ][ Assistance ][ Related ]
The HP 8591EM is a stand-alone, automated EMC precompliance analyzer that reduces the time it takes to find, measure and document radiated and conducted EMI emissions. It belongs to the HP 8590EM series of EMC analyzers, which do not require an external computer and automation software to perform automated EMC measurements. With an upper frequency of 1.8 GHz, the HP 8591EM can perform precompliance tests on products with clock frequencies up to 108 MHz. The HP 8591 EM has two modes of operation: EMI analysis and spectrum analysis. With the press of a key, this analyzer converts from EMC analyzer to full-function spectrum analyzer for use in a wide variety of non-EMC applications. Based on our highly versatile HP8590 E-series spectrum analyzers, this EMC analyzer simplifies the EMC measurement process with fully integrated automation features.
