Solution for Conduction EMI
|
| The EMC Type and Path |
|
EMC =EMS + EMI
|
Radiation via air & Conduction via power
|
| GSP-9330 EMC Pretest Dedicated Functions |
|
Built-in EMI test standards

|
| Key features of GKT-008 |
| 1. Small size, high sensitivity |
|
GKT-008 vs conventional probes
|
Identify EMI source better by small size
|
|
ANT-04: higher sensitivity than H probe
|
ANT-04: higher sensitivity than E probe
|
| 2. No directivity issues for ANT-04, ANT-05 |
|
H probe: Different results with different angles
|
ANT-04: Similar results with different angles
|
|
Working principle of conventional H probe (I)
|
|
|
H probe detects much more while deviating 1cm
|
ANT-04 detects more while aiming the center
|
|
Why H probe aiming at center detects less signal?
|
|
| 3. Detecting separate H field and E field vs Sensing EMI energy |
|
H probe’s results differ from E probe
|
|
|
H field & E field are two components of EMI
|
|
|
ANT-04 and 05 directly sense EMI energy
|

|
Far field response estimation
|
● Convert the near field measurement results to far field response (3m or 10m can be selected). ● Helpful to confirm whether the EMI trimming works or not.
