Harmonics & Flicker

Look for the following features and specifications:

• User-selectable test limits
• User-selectable test parameters and data-display options
• Key equipment under test electrical parameters (database) updated continuously
• Start and stop flicker tests with a single mouse click

Automotive EMC Test Systems

In Europe, look for immunity standards based on ISO 7637 and 42V readiness.

Some test-equipment may peform:

• Automotive Transient Immunity Tests fully (compatible with every immunity requirement from ISO 7637-2:2004)
• Complex Voltage Variations, Magnetic Field Test, Sinusoidal Burst (should include features for simulation of vehicle voltage starting profiles, dips and drops, transformer coupled and other sine wave noise and magnetic field immunity testing)
• Power Amplifier/Battery Simulations (pulse 4, pulse 2b and other immunity testing based on ISO 7637)
  • Large inrush current cabability
  • Capacitive stability mode
  • High bandwith up to 150kHz
  • Fast slew rate
  • Two output ranges for power efficiency
  • Two gain settings for universal use
  • Sense lines for cable voltage drop compensation
  • Four quadrant operation
• Transient Generation / Load-Dump Generation (e.g., For many classic Japanese immunity tests)

Look for software that performs immunity applications, for full control of the capacitive discharge transient simulations, supply voltage variations and other automotive immunity tests.
