Calibration kit for EFT / Burst Capacitive coupling clamp INA 3425
2.2 Preparation for operation
The test rig is to be constructed in accordance with IEC / EN 61000-4-4 Ed 3.0 :
2012 with special reference to:
– Operation preferably in a screened room to protect the environment
– Distances to the EUT and peripherals to be as specied in the standard
– Good and large area contact to the earth plane
Fig. 2: Example of calibration test setup as described in IEC / EN 61000-4-4 Ed
3.0: 2012
2.3 Operating
– Set up Burst / EFT generator, oscilloscope and coupling clamp to calibrate on
an adequate ground plane
– respect setup as specied in IEC 61000-4-4 Ed 3.0: 2012
– Use CAS 3025 (INA 265A) to veriy the compliance of the reference burst / EFT
generator, save waveshape and register pulse parameters for reference.
– Place the INA 3425 into the coupling clamp to be calibrated – position the
whole as specied. Note that the Teseq sticker at the end of INA 3425 is placed
the way that when in line with the end of the coupling clamp , the distances
to the connecting adapter will automatically be < 10 cm as required by the
standard.
