The affordable EMC RF Signal Generator
Flexible Accurate Extensible

An important part of an EMC immunity test system is the RF signal generator. It
produces the modulated or un-modulated RF signal at a certain frequency and
signal level. The latest expansion of the product range of DARE!! Instruments is
the RadiGen® series of affordable EMC RF signal generators. These generators
are designed for EMC test purposes in order to perform fast and accurate EMC
tests without the need of external modulation sources.
Flexible
The RadiGen® EMC RF signal generator is available in three versions; the
RGN0230A covers a frequency range from 9 kHz to 230 MHz, RGN6000A from
80 MHz to 6 GHz and RGN6000B from 9 kHz to 6 GHz. These versions offer a
solution for all conducted and radiated immunity test applications. The generator
provides CW, AM and Pulse modulated signals using an internal modulator. The
Pulse on/off times can individually be set between 200 ns and 100 seconds. Pulse
duration/repetition times can be configured separately offering very flexible Pulse
modulation settings including Automotive Radar Gated Pulse tests (Ford, GM
and PSA). The RGN0600B RF signal generator has 2x SMA connectors, 1x SMA
for 9 kHz to 230 MHz (low band) and 1x SMA for 80 MHz to 6 GHz.
Accurate and pure signal
The RadiGen® is an accurate RF signal generator with a frequency error of less
than 20 ppm and modulation accuracy better than 2 %. These figures make it the
perfect device for EMC immunity testing. Problems with non monotone
behaviour and glitches in the output level are often encountered with generators
using fixed step attenuators. The RadiGen® generator makes use of a full range,
analogue output attenuator. This results in a complete monotone increase of
output level without any glitches. Due to this, problems with levelling algorithms
in EMC test software can not occur with this generator. Apart from this,
mechanical defects to the output attenuator can not occur, resulting in a better
Mean Time Between Failures.

Extensible
The RadiGen® generator is delivered as a very compact, one slot, plug-in card
designed to fit into the modular RadiCentre® system. The RadiCentre® is
available as a one, two or seven slot system. Such a system can, for example,
contain a RF signal generator (RadiGen®), one or more E-field probes
(RadiSense®), coax switch cards (RadiSwitch®), RF power meters (RadiPower®)
and turntable/antenna tower controllers (RadiControl®). Of course it is possible to
build even larger systems by combining any number of RadiCentre® systems.
Easy to use
The RadiCentre® systems are “Plug and Play”, which means that every plug-in
card is automatically recognised and initialised by the RadiCentre® and
immediately ready to use. The user can configure and control the system using
external PC software or through the TFT touch screen (only on 2- and 7-slot
RadiCentre®).
Software support
The RadiGen® and RadiCentre® are software controllable with USB, RS-232 and
IEEE-488* (*optional for 2- and 7-slot RadiCentre®). Besides the RadiMation®
integral EMC measurement software the system can be controlled by other EMC
measurement software packages using the RadiGen® software command codes.
