• Connections: EUT “Fail”, EUT monitoring by external multimeter, e.g. DUT signal
• Calibration of coupling / decoupling devices and EM clamp is performed automatically
• Extensive additions like attenuators, calibration kits, etc. deliverable.
• Directional Coupler ( DC )
A directional coupler is used to measure and control the forward power of the amplifier – see the
standard IEC / EN 61000-4-6, 2014. The quality of the built-in amplifier allows control of the level
data through the system - see chapter 6.4 in the standard with respect of two methods. That means
a built-in directional coupler is in our test system not (necessarily) required. It can also be retrofitted.
Or an external directional coupler can connect - see also following selection table.
However, the control on the forward power during a test is the preferred method.
This means a generator with built-in directional couplers meets the requirements of the standard and
the auditors. There are no discussions on the procedure.

Introduction
The test generator generates interferences as defined in IEC / EN 61000-4-6 - Immunity to conducted
disturbances, induced by radio-frequency fields. The standard described a test setup, in which can influence
these high-frequency interferences without a complicated structure with antennas, field instrumentation and
shielded rooms on a EUT. Via coupling networks and coupling clamp's sine waves are induced directly into
power and signal lines. The EUT keeps its usual place in the installation; the complete unit can be tested in
its function.
