Atec Teseq-Schaffner-NSG-5600 - Manual (Page 8)

Matching the capabilities of the FG 5620, up to
±15V and 5A can be delivered by the power amplifier
module, which means that for many applications –
namely for small 12V component and subassembly
testing – the use of an external battery simulator is
unnecessary. The frequency range and bipolarity
ensure that the module will find a wide range of
applications. The EUT current can be measured and
a program-controlled current limit can be specified.
The PA 5640 also serves as a power driver for the
electromagnetic coils used in magnetic field tests
and as an amplifier for conducted sine wave tests.
Separate current measurements for the two types of
tests ensure correct control of the test conditions. Magnetic field tests. The NSG 5600 configuration is
expanded by the addition of magnetic field antennae
for the execution of magnetic field tests. Either
simple current loops or Helmholtz coils are used de-
pending on the relevant test standard. The PA 5640
is equipped with a control input for the connection
of a magnetic field measuring sensor for the precise
regulation of the generated field.
