EMS simple measurement<\/p>\n\n\n

Application<\/h2>\n

Simple radiation immunity test of 80 MHz to 500 MHz, 30 V\/m can be performed for preliminary evaluation before bringing the EUT to the EMC test site and for confirming the effect of the countermeasure. <\/p>\n

In order to perform a strong electric field radiation immunity test of 30 V\/m at a low frequency of 80 MHz to 500 MHz in the Electromagnetic Anechoic Box which is a very narrow space compared to an normal Anechoic Chamber, a small loop antenna is installed close to EUT (5 cm)<\/p>\n\n\n\n

Solution<\/h2>\n

Procedure of measurement<\/h3>\n
    \n
  1. nstall an electric field probe for calibration at an EUT installation position.<\/li>\n
  2. djust the level of an signal generator to achieve a desired field strength.<\/li>\n
  3. Determine a level of the signal generator.<\/li>\n
  4. Install the EUT and set the level of the signal generator determined by calibration.<\/li>\n
  5. Check whether the EUT malfunctions.<\/li>\n
  6. Repeat the measurement while moving the antenna up, down, left and right.<\/li>\n<\/ol>\n
