Atec Teseq-Schaffner-NSG-5600 - Manual (Page 4)

The function generator FG 5620 is used universally
throughout the NSG 5600 for the control of DC
sources and power amplifiers. The AutoStar
TM soft-
ware defines the necessary voltage/frequency con-
ditions. 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 Clone
TM , e.g. a memory map of values from a
storage oscilloscope or other external application,
the FG also generates waveforms that can be diffi-
cult 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 sub-
sequently 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 con-
trol the relevant number of sources. All the gener-
ators used are programmed separately and run
synchronously based on a master-slave relationship.

Single-click programming plus the powerful Clone TM function make this the
most powerful automotive EMC function generator in the world.
