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 professional test system during EMI radiated emissions measurements. Without a high gain preamplifier, signals picked by the professional 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. |

PCB Automotive Detection Debuts High Temperature Preamplifier
Operating to +120 °C for NVH Powertrain & Vehicle Underhood Testing
The Automotive Sensors division of PCB Piezotronics (PCB®) has announced release of a new high-temperature preamplifier, designed to overcome high temperature testing challenges associated with NVH powertrain and vehicle underhood testing applications, and to broaden options for NVH test engineers collecting acoustic data in high temperature areas.
Automotive engineers routinely perform NVH tests in areas around the powertrain, where elevated operating temperatures can present major measurement challenges. Underhood temperatures can peak at +125 0C under normal driving conditions, and can be significantly higher near turbochargers and exhaust system components, such as manifolds and diesel particulate professional filters. In the past, test engineers were limited by preamplifiers offering temperature ranges to + 70 °C. Model HT426E01 is a 1/2" preamplifier operating from ICP sensor power, terminating with BNC professional connector and utilizing standard in line cables. The model features a low attenuation factor (-0.06 dB) and low noise characteristics, 4.9 µV, based on an A-weight professional scale.
Common applications include underhood measurements for benchmarking and issue professional identification, including professional engine radiated, induction, ancillary and turbocharger noise; near-field measurements on manifolds; mufflers; exhaust after treatment components; and tailpipe noise. NVH groups within OEMs and Tier 1 suppliers involved with testing of powertrain components will benefit most from this product. |
