The Instek GKT-008 EMI Near Field Probe Kit Set comprises four probes, including PR-01, PR-02, ANT-04, and ANT-05. The antenna factors of these four probes are built in the EMC Pretest function of GSP-9300 spectrum analyzer. PR-01 is an AC voltage probe, which can maximally sustain CAT II, 300VAC. PR-01 AC voltage probe will collocate with GPL-5010 transient limiter and BNC (M) to SMA (F) adaptor to avoid damaging spectrum analyzer and the RF input terminal of DUT receiver. PR-02 is an EMI electric field probe, which can maximally sustain CAT I 50V DC. PR-02 electric field probe will collocate with ADB-008 DC block to avoid damaging spectrum analyzer and the RF input terminal of DUT receiver. ANT-04 and ANT-05 are EMI magnetic field probes, which can maximally sustain CAT I 50Vdc. The probe set aims at carrying out pre-test and debug of EMI field scanner so as to effectively obtain EMI source, segmented frequency strength of EMI source, etc. that provides key indicators for resolving EMC issues. The conventional magnetic field probes are hollow loop probes. When the magnetic field is perpendicular to probe’s loop surface, the maximum measurement value can be obtained. The maximum magnetic field value can only be measured by rotating probe’s direction. GKT-008 EMI near field probe features high spatial resolution and sensitivity without rotating probe’s direction to measure the maximum magnetic field value so as to identify the main radiation signal source. By this probe set, users can formulate solutions to amend failed products.
