Emissions measurements of the electrical field strength in the frequency range of 1 GHz to 40 GHz are carried out in an anechoic chamber or at an open area test site. Usually these measurements are very time-consuming as the points of maximum radiation have to be found over all angular positions of the device under test (DUT) as well as over all antenna heights. DUTs with strongly directed radiation patern above 1 GHz require high angular resolution, which means very small angular steps of the turntable to get the accurate position of the maximum emission, making the testing procedure even more time-consuming.
The EMI64k, the new automation software suite of GAUSS INSTRUMENTS, allows to embed your TDEMI receiver in a fully automated test environment. A full automation of EMI testing according to all commercial and military standards is available with this software suite. Using the capabilities of the TDEMI® X with a gapless processing and full quasi peak detection the EMI64k is the only software that provides a full automation even under conditions of sporadic interferences or drifting emissions. This unique technology avoids manual searching of peaks and improves the overall test quality. In addition the complete radiation pattern is measured at all frequencies with Quasi-peak.
The world’s fastest EMI receivers – the TDEMI eXtreme series (TDEMI X) of GAUSS INSTRUMENTS covering the frequency range from DC – 40 GHz and providing unique features as 645 MHz CISPR compliant real-time bandwidth, Multi-GHz Real-time Scanning and the lowest displayed average noise level at 40 GHz can now be equipped with an additional ultra-low noise pre-amplifier for the frequency range 30 MHz – 1 GHz. This novel pre-amp provides lowest noise figure and highest dynamic range - both at the same time. High linearity and lowest displayed inherent noise is achieved by a patented technology using pre-amps with low noise figure, pre-selectors and a special circuit monitoring the linearity reserve of the pre-amp.
Emissions measurements of the electrical field strength in the frequency range of 1 GHz to 40 GHz are carried out in an anechoic chamber or at an open area test site. Usually these measurements are very time-consuming as the maximum radiation has to be found over all angular positions of the device under test (DUT) as well as over all antenna heights. DUTs with highly directive radiation characteristics above 1 GHz require very small angular steps of the turntable for getting the accurate position of the maximum emission, making the testing procedure even more time-consuming.
Measurements of radiated emissions in the frequency range up to 1 GHz are performed in a semi-anechoic chamber or on open area test sites (OATS). Such measurements are very time consuming as according to CISPR and FCC Standards the measurements have to be performed at several antenna heights and all angular positions of the device under test. In the past the total test time was reduced by performing pre-scans with peak detector and short dwell times and final maximization carried out at individual frequencies only. During the pre-scan procedure overview measurements are performed to search for the frequencies with maximum emissions. A list of suspicious frequencies (peak list) is generated. Then at these frequencies the final measurement is performed in single frequency mode with longer dwell times.
