• Most products must meet FCC, CE, and other EMI/EMC requirements and pass the related laboratory tests.  Finding and fixing EMI/EMC compliance problems after a product is designed and prototyped is often difficult and expensive.  In most cases, time and resources of a design for EMC review spent early in the design process will substantially reduce the ultimate cost of compliance.  

• ESDI has a very strong design for compliance track record where it has been able to review and influence EMI/EMC design at the system level and PCB / electrical design level.  ESDI has also helped troubleshoot and remedy problems found during compliance testing.

• In one example, a client had ESD testing problems with a device that had been designed off shore.  An EMC consultant had recommended an effective but expensive set of remedies.  ESDI was able to remedy the problem to the client's requirements by adding two capacitors in the correct places on the PCB.

• ESDI has also successfully designed shield-free products including one which was required to meet the more stringent class B standard.  Depending on clock frequencies, this can be difficult to accomplish.  Local shields at the pcb level have also been effective in dealing with plastic enclosures.

• ESDI has modeled input protection circuitry using Spice transient analysis by characterizing it in the frequency domain with a spectrum analyzer and tracking generator.  This modelling was sufficient to allow a very robust video circuit protection without degrading the high frequency video bus.

• ESDI applies its EMC lab troubleshooting experience from an electronic design perspective, always looking to suppress the noise at its source.  Recent equipment additions include a 6 GHz realtime spectrum analyzer, a 1GHz RF current probe, and a 1GHz Vector Network Analyzer.
