Utilizing the only automotive EMC specific synchronized, multi-channel function generator (FG) in the world, the software integrates the various system components seamlessly into the overall system concept with uniform operating procedures and user guidance together with a comprehensive test result reporting facility.
NSG 5600. Designed to be used either alone or in combination with a NSG 5500 system, the NSG 5600 is designed to simulate events that include voltage dropouts, sinusoidal noise and other events superimposed on the automotive battery: Dips and drops, and ISO and SAE pulse 2b and pulse 4 and other starting profiles. The NSG 5600 is the leader in synchronized voltage variations, such as power cycling tests (on up to four FGs) as required by various standards such as CI 230 defined in the Ford ES-XW7T- 1A278-AB and AC standards. Additionally, the NSG 5600 may be configured for magnetic field immunity testing. The basic NSG 5600 includes one FG 5620 but additional capability may be added using any of the modules on the following pages.
NSG 5600 concept. Schaffner continues to utilize its well accepted modular concept of a 19” basic chassis containing all the power supply components and, if required, the sinusoidal burst-transformer, the control and signal bus boards as well as the common inputs and outputs for the safety circuits and signals for the expanded control and monitoring of the test. The CAN-bus, already well known in automotive technology circles, is used as the system bus.
Therefore, as with the complimentary NSG 5500, Schaffner’s modular concept, new capabilities can be quickly implemented. Modular and flexible test systems equal protection of investment for the user. Schaffner offers rack-mounted solutions with suitable internal cabling and mains control panel as accessories, configured to the user’s needs.
Combined with a power amplifier/battery simulator, the NSG 5600 represents the
most powerful solution for battery voltage variation simulation.

FG 5620
Function generator
Single-click programming plus the powerful CloneTM function make this the
most powerful automotive EMC function generator in the world.
The function generator FG 5620 is used universally throughout the NSG 5600 for the control of DC sources and power amplifiers. The AutoStarTM software defines the necessary voltage/frequency conditions. The controller converts this information into algorithms for the FG (function generator), which creates an image of the requirements in its own memory and then generates the output signals for the addressed power modules during the test run. All the requisite waveforms can be created numerically from the basic functions or by loading a CloneTM, e.g. a memory map of values from a storage oscilloscope or other external application, the FG also generates waveforms that can be difficult to describe mathematically or where real-world events need to be simulated. AutoStar supports any external application that can output an ASCII list, MathCAD or Microsoft Excel, for example.
Every card incorporates a second channel for the
control of a further source with a programmable, steady state voltage as well as an output for setting the current limiting of the source. The main output signal consists of analog voltage of -10 to +10V – a standard that is used by the majority of voltage sources. Limits are only imposed by the sources used for a particular application. For this reason, Schaffner offers a full range of standard-compliant battery simulators.
The FG 5620 is a module equipped with a function generator board. A second board can be added subsequently at any time. The FG 5621 is delivered equipped with two function generators.
Two of these modules can be used in a system, i.e. up to four function generators are available to control the relevant number of sources. All the generators used are programmed separately and run synchronously based on a master-slave relationship.
