How to perform a MIL-STD CS114, Conducted susceptibility, bulk cable injection test[edit]

This application note explains how the MIL-STD CS114, Conducted susceptibility, bulk cable injection test can be performed with RadiMation®

The exact requirements and test methods for the CS114 are specified in the MIL-STD-461.

Necessary equipment[edit]

The following devices are necessary to execute this test:

  • Signal generator
  • Amplifier
  • Coupler
  • Forward power meter
  • Reflected power meter (optionally)
  • Current sensor
  • Sensor power meter / Analyser
  • 50 Ohm load
  • 50 Ohm attenuator
  • LISN
  • Current injection device
  • Current injection calibration jig (Calibration fixture)
  • Cable drivers with corrections

Configuration of the test sites[edit]

Calibration[edit]

First create a correction file in RadiMation® and specify the applicable test level (See 'TABLE IV CS114 limit curves.' and 'FIGURE CS114-1. CS114 calibration limits.'). In this example the limits for 'Aircraft (External or safety critcal) / Curve 5 are configured.

Make sure to remove the Correction column and add the current column with the unit set to dBuV.

Verification[edit]

EUT Testing[edit]

Conclusion[edit]

The sensitivity of an EUT to incoming electromagnetic interference. This is equivalent to the term Immunity. RadiMation® always uses the term Immunity.

The ability of an EUT to be immune to incoming electromagnetic interference. This is equivalent to the term susceptibility that is used by some standards.
