EMI Test - Faster - Easier!

 

Spectrum Analyzer GSP-9330:

Frequency Range:3.25GHz
EMC Pretest dedicated functions
Peak, QP, Average detectors

Spectrum Analyzer GSP-9330:

EMC =EMS + EMI

Radiation via air & Conduction via power

GSP-9330 EMC Pretest Dedicated Functions

Built-in EMI test standards

Log scale frequency axis and peak table

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

GSP-9330 built-in GKT-008 associated functions

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.
