SpectrumShot – EMI dedicated function, Users can use the external software SpectrumShot for EMI test report management and assessment. Users can select the required CISPR EMI regulation for conduction and radiation measurement.

GKT-008 EMI Near Field Probe 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 the GSP-9330 spectrum analyzer.

ANT-04 and ANT-05 are EMI magnetic field probes, which can maximally sustain 50Vdc. ANT-04 and ANT-05 magnetic field probes will collocate with ADB-008 DC block to avoid damaging spectrum analyzer and the RF input terminal of DUT receiver.

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) adapter 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.

GLN-5040A Two-Line V-Network(LISN) that met CISPR16-1-2:2006 standard is a required product for EMI conduction testing.

Built-in transient limiter and fixed 10dB attenuator to effectively protect spectrum analyzer.Built-in 150 KHz high pass filter switch to prevent spectrum analyzer or DUT receiver overload caused by low-frequency high amplitude signals.
Provide artificial hand function to simulate human hand impedance on handheld device (such as electric drill) measurement.

50 Ω output impedance and BNC output adaptor can collocate with spectrum analyzer.

Provide stable impedance for DUT and reference ground under testing frequency range.

Isolate the interfering signals produced by city electric power from the testing circuit to provide pure DC and AC power to DUT.
Couple DUT interfering voltage with spectrum analyzer.

Before connecting LISN, users can connect a GIT-5060 isolated transformer as the following diagram to balance grounding L and N phase current by ELCB function in order to realize a safe grounding.

Under the necessary circumstances, GIT-5060 can be used if isolated transformer is required. It can maximally sustain consecutive current of 4A and its maximum capacity is 900VA that satisfies most testing requirements.

Why do you need a transient limiter?

Large transient signals will enter spectrum analyzer if the system experiences unexpected power outage or sudden errors from power supply terminal. For an unstable system, a transient limiter can disrupt large signals and prevents them from going into equipment to cause damage.
