The amplifier generates dips and drops, short interruptions and voltage variations to simulate a wide range of phenomena occurring on a vehicle wiring harness. With unlimited operation from -15V to +60V, this powerful DC voltage source simulates a wide number of battery supply waveforms used by manufacturers in the automotive industry as well as for international quality standards. Uses include military, avionics and automotive testing environments.
The VDS 200Q Series are fast bipolar amplifiers which operate across all four quadrants that sink as well as source current. This allows the new simulators to drive capacitive loads and absorb energy feedback from the device under test (DUT) up to the nominal current.
A very low source impedance of less than 10 mΩ and a high bandwidth of 150 kHz (full signal) enables these new sources to support low voltage drop, class-leading inrush current and extremely fast recovery. A “QuickStart” feature allows parameters to be adjusted during test to evaluate the DUT’s susceptibility level. And, while many manufacturer-specific waveforms such as pulse 2b (per ISO 7637-2) and pulse 4 (per ISO 16750-2) are pre-programmed, adding an external signal generator allows the VDS 200Q to generate even more complex waveforms.
Test routines are programmed using the front panel with menus and function keys. The optional ISO control software automatically configures according to the connected EM TEST generators and provides an interface for accurate control and reporting functions. The EM TEST standards library is continually updated with the most current international and automotive manufacturers’ standards requirements.
