EFT Burst as per IEC 61000-4-4
Burst Module 5/50ns
Warning
If the user reduces the test voltage in
Quick Start
or in the
Manual Standard Test Routine
, the
storage capacitor will be
discharged only by the burst pulses
. The result is a higher test
voltage on the EUT than indicated on the display until the storage capacitor is discharged to the
preselected value.
If the voltage reduction is several 100V the discharge time to the correct test voltage can be
some seconds. The discharge time depends on the repetition rate tr and the duration td of the
burst pulse.
Pressing STOP / START will discharge the storage capacitor over the discharge resistor
immediately. After the START the test will continue with the correct voltage level.
