Page 5: Introduction
Introduction The ETS-Lindgren EMGen™ RF Signal Generator Plug-in Card is a modular signal generator with AM, FM, and pulse modulation, covering a frequency range of 4 kHz to 6 GHz. EMGen is designed for EMC testing, and quickly and accurately performs EMC tests without the need for an external modulation source. -

Page 7: Processor Requirement
Processor Requirement Note: The 2-slot and 7-slot EMCenter require an ARM processor board with firmware version 3.3.3 or higher to operate the EMGen interface card. 2-slot and 7-slot EMCenter systems utilizing an X86 processor board and/or firmware version 3.3.0 or older are not supported and will not communicate with the EMGen interface card. -
Page 8: How To Use Gated Pulse Modulation
How to use Gated Pulse Modulation Several automobile manufactures have written standards in which they subscribe the Automotive Radar Pulse tests. These tests consist of an N-number of pulses in a certain period of time. When the number of pulses is reached, there must be no more output for the remaining time during that period. - Page 9 The standards describe the pulse waveform by means of a Pulse Repetition Rate (PRR) and Pulse Duration. The EMGen plug-in card, on the other hand, uses Pulse ON and Pulse OFF (PULSe:WIDTh and PULSe:DELay) times. As a result the PD and PRR numbers must be calculated to Pulse ON and Pulse OFF (PULSe:WIDTh and PULSe:DELay) times, according to the example below: Example: The Ford standard EMC-SC-2009 describes:...
- Page 10 Limitations: The Pulse ON and OFF times apply to the specific limitations to the number of pulses per period for the Gated Pulse Modulation. The EMGen system user interface makes use of equations to intelligently adapt the buttons, prohibiting invalid settings. When the EMGen plug-in card is controlled externally by PC- software, these limitations must be controlled by the PC-software.
