Page 8: Introduction
1.0 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 9: 2-Slot And 7-Slot Emcenter Processor Requirement
2-Slot and 7-Slot EMCenter 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 7003-002 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 10: How To Use Gated Pulse Modulation
FM modulation — The EMGen supports FM modulation deviations of 1 Hz to 100 kHz and modulation frequencies from 1 Hz to 100 kHz. Pulse modulation: 200 ns - 100 s — The EMGen supports pulse modulation with ON- and OFF times ranging from 200 ns to 100 s with a resolution of 100 ns. - Page 11 The EMGen plug-in card is capable of generating the necessary RF bursts according to these automotive standards, using the Gated Pulse Modulation. Normal pulse modulation must be used to set the Pulse ON and Pulse OFF times (these are called, respectively, PULSe:WIDTh and PULSe:DELay, in the command set of the EMCenter system user interface).
- Page 12 Example: The Ford standard EMC-SC-2009 describes: PRR = 300 Hz, PD = 3 µs. N =50 pulses per second. So the period time of the Pulse Modulation is TPRR = 3,333 ms For the EMGen this means: The Pulse ON time, or PULSe:WIDTh equals PD = 3 µs The Pulse OFF time, or PULSe:DELay equals TPRR –...
