Preamplifiers for EMI / EMC testing from 100 Hz - 40 GHz

Broadband, high gain with minimum gain variation for accurate EMC measurements.

Com-Power broadband high gain preamplifiers were designed for electromagnetic interference (EMI) testing and certification.  EMC test labs use preamplifiers to improve sensitivity of the test system during EMI radiated emissions measurements. Without a high gain preamplifier, signals picked by the antenna that have amplitudes below the noise floor of the test system cannot be measured. The preamplifier gain has minimum variations for the entire operating frequency range for accurate emissions measurements. The Com-Power preamplifiers were primarily intended for EMC applications. However, it can be used for other applications that require signal amplification.

Model	Typical Gain (dB)	Flatness (dB)	Frequency Range (MHz)
PA-010	39	± 2	0.001-30
PA-103	32	± 2	1 -1000
PA-118	24	± 2	500 - 18000
PA-122	30	± 2	500-22000
PA-840	25	± 2.5	18000-40000

Calibration

All Com-Power preamplifiers are individually calibrated before shipment with equipment traceable to National Institute of Standards and Technology (NIST). The data and the certificate of calibration are shipped with each unit.
