EMC-Test Equipment for the electrical installation of vehicles
The EMC test system is designed for testing electromagnetic immunity of the electrical installation of vehicles and components against supply line transients.
The CAR-SYS allows, in its basic configuration generation of transient immunity test pulses, pulse #1, #2 and #3. It contains a triggerable load switch, an Ethernet interface board and an integrated fast pulse voltage divider to measure the impulse in the electrical.
A microprocessor-controlled 7" touch screen display unit is integrated and permits easy operation of the generator. The software program CAR-remote permits the PC control of the generator via Ethernet and also allows the standardized documentation according to IEC 17025 and the evaluation of test results. The user can use the standard test routines (ISO, VG, Car manufacturer specific) or define his own test sequences. It is equipped with an Impulse Recording Function (IRF) to record definite impulses (with oscilloscope).
Furthermore, nearly all customer-specific impulse adjustments are possible by flexible software control.
The CAR-SYS excels by its compact design, simple handling, and precise reproducibility of test impulses. High-voltage switching is accomplished utilizing a maintenance-free semiconductor switch.
Optionally, it can be expanded with the electronic power supply:

The CORTEX RSR-RF (-40 or -200) stands as a digital recorder that plays a vital role in capturing and reproducing the RF analog signal received by the antenna before any processing occurs.
It’s an essential component in a Telemetry Station, ensuring the utmost availability of crucial data, particularly in cases where on-board recording is not feasible.
Data collected in-flight offers extensive post-processing flexibility. You can fine-tune various settings in the receiver, the bit synchronizer, and the decommutator to maximize the extraction of data, a feat achievable only with RF recording. Furthermore, it serves as an invaluable tool for test range qualification ahead of test flights.
