EMI/EMC Testing

064650_EMI-test-setup
Electromagnetic interference (EMI) occurs when an electronic system receives unwanted electromagnetic energy from an external source—anything from lightning to power lines to cell phones. EMI can degrade a system’s performance or make it stop working altogether.

Electromagnetic compatibility (EMC) refers to a system’s ability to avoid causing EMI in itself or other systems. Virtually all products have to meet an appropriate EMC standard, whether they’re intended for military, industrial, or commercial use.

X-ES engineers perform EMI and EMC testing to verify that our products work correctly in the electromagnetic environments where they are expected to function. Testing occurs in two stages:

  • Pre-qualification testing occurs in an on-site EMI chamber, using a Rohde & Schwarz ESPI3 Test Receiver.
  • Full qualification testing occurs off-site at independent EMI testing facilities.

On-site pre-qualification testing allows our engineers to identify and resolve many issues early in the development process, before the full qualification testing is scheduled and paid for. This results in lower costs and a faster, smoother qualification testing process.

On-Site Pre-Qualification EMI/EMC Tests

X-ES engineers have experience performing the following tests in our on-site EMI test lab:

  • MIL-STD-461 CE101: Conducted Emissions (30 Hz to 10 kHz)
  • MIL-STD-461 CE102: Conducted Emissions (10 kHz to 10 MHz)
  • MIL-STD-461 CS101: Conducted Susceptibility (30 Hz to 150 Hz)
  • MIL-STD-461 CS115: Conducted Susceptibility (30 Hz impulse excitation)
  • MIL-STD-461 RE102: Radiated Emissions (10 kHz to 3 GHz) (conduction via power lines and radiated with the use of field probes)

EMI/EMC Qualification Tests

X-ES engineers have experience performing the following tests at independent EMI testing facilities for system- or board-level qualification efforts:

  • MIL-STD-461 CE101: Conducted Emissions (30 Hz to 10 kHz)
  • MIL-STD-461 CE102: Conducted Emissions (10 kHz to 10 MHz)
  • MIL-STD-461 CS101: Conducted Susceptibility (30 Hz to 150 kHz)
  • MIL-STD-461 CS114: Conducted Susceptibility (10 kHz to 200 MHz)
  • MIL-STD-461 CS115: Conducted Susceptibility (30 Hz impulse excitation)
  • MIL-STD-461 CS116: Conducted Susceptibility (sinusoidal transients 10 kHz to 100 MHz)
  • MIL-STD-461 RE102: Radiated Emissions (10 kHz to 18 GHz)
  • MIL-STD-461 RS103: Radiated Susceptibility (2 MHz to 40 GHz)
