Default error estimate in case of insufficient data. Vector-valued integrand. Binary precision to be used. Target error bound. Integrate a one-argument vector-valued function numerically using Gauss-Legendre, setting the number of nodes. N — integer default: 3. Number of nodes to use. The nodes and weights are calculated in the real field with prec bits of precision. If the the vector space in which f takes values is over a field which is incompatible with this field e.
We use the recurrence relations for Legendre polynomials to compute their values. This is a version of the algorithm that in [Neu] is called the REC algorithm. The number of nodes. Must be 3 or even. Highest measurement speed. Incredible dynamic. Traditional and FFT-based Technology. New dimensions for pre-certification testing.
Very compact design. Great variety of functionalities. For completely new possibilties in EMC analysis and debugging with an even further reduced measurement uncertainty. Best in class RF performance. The fastest stepped scan receiver on the planet. The fastest FFT-based receiver on the planet. All at the same time. All in just one box. Due to its various operation modes it can be used in a vast range of applications, e. MILG, but also its previous versions and revisions as well as avionic standards e.
DO or any OEM standards. A wide range of configuration possibilities are available in addition as well as full automation software packages making the TDEMI ULTRA the perfect match and the most cost efficient solution you have ever seen in your lab. The TDEMI System simplifies and tremendously speeds up the measurement procedure but it also enhances the quality of your conducted emission measurements at the same time.
Thus you get to your final test result just within a few seconds - and you're done. All phases are measured fully automatically. The report generator creates the test report according to the given limit lines selected or specified by the user. Measurements of disturbance power are carried out using an absorber clamp that is moved along the cable of the device under test. Instead of measuring many positions afterwards maximazation and finally re-measuring the ciritcally frequencies only which is a very time-consuming and out of date procedure - now the complete spectrum up to MHz can be measured with quasi-peak in real-time by the TDEMI X receiver series which only takes around 20 seconds - depending on the speed moving of the clamp along the cable track.
By using the max hold function the maximum emission level of all!! The report generator documents all the maximas and the test report is generated fully automated. Complete setups incuding limit lines, transducers and all other applied settings can be stored and just recalled the next time by the very easy-to-operate instrument's software interface.
Originated by the conventional heterodyne receivers and its very slow sequential frequency scanning technology prescans are performed to detect some critical frequencies only to reduce the total scan time of the following final measurement to be carried out at those identified frequencies only. By using the TDEMI X receiver the measurement is performed with quasi-peak detector and carried out at up to 64, frequencies in parallel.
Thus it is possible to perform your final quasi-peak measurment in real-time - measuring all frequencies and all position of your DUT - resulting, for the very first time, in a full quasi-peak characterization of your DUT.
This speeds up your testing by orders of magnitudeand at the same time the quality of your measurements is increased and the measurment uncertainty is reduced by orders of magnitude. The measurement of radiation patterns can be performed and visualized in 2D and 3D images to identify the radiating sources and also the test reports can be generated fully automated.
Typically emission measurements above 1 GHz are carried out at several angular positions for horizontal as well as vertical polarization.
Instead of spending hours with a conventional heterodnye receiver, the TDEMI X coming with its MultiGHz real-time scanning feature tremendously speeds up your measurements and testing procedures.
Instead of carrying out a scan per angular position each, rotating the turntable continuously while measuring in real-time. MaxHold is used to obtain the maximum emission over all positions. By the report generator the maxima are calculated and listed in a table and the report is generated.
The result is again a reduction of the overall testing time by magnitudes. For our ultra high-speed analog-to-digital converter systems, manufactured in impeadance controlled multi-layer technology with up to 12 layers, special high-performance analog and mechanical components are needed.
Such high performance systems are assembled in mechanically precise manufactured enclosures machined from a single piece of aluminium thus providing an excellent heat dissipation and best long term stability over the years of operation. Such circuits have been developed and optimized especially for the application in EMC measurements.
