With a frequency range of 1 MHz to 3 GHz, it enables accurate evaluation of field strength and distribution during development, validation, and troubleshooting.\u003c\/p\u003e\n\u003cp data-start=\"606\" data-end=\"1006\"\u003eIn practice, ESD Guns customers use the EFM 04 to measure and verify electric fields generated by ESD simulators, particularly in setups based on IEC 61000-4-2. Engineers position the probe near the device under test or along the discharge path to evaluate field strength and distribution during ESD events, ensuring consistent and repeatable test conditions prior to compliance testing.\u003c\/p\u003e\n\u003cp data-start=\"1008\" data-end=\"1295\"\u003eThe EFM 04 is also widely used for calibration and validation tasks, helping confirm that ESD generators are operating within expected parameters. It allows users to compare field levels across different setups, optimize test configurations, and troubleshoot unexpected test results.\u003c\/p\u003e\n\u003cp data-start=\"1297\" data-end=\"1610\"\u003eIn R\u0026amp;D environments, the EFM 04 supports early-stage analysis of field behavior, enabling engineers to identify issues related to shielding, layout, and component sensitivity. Its compact design and reliable performance make it a practical tool for engineers working in EMC, compliance, and test laboratories.\u003c\/p\u003e\n\u003ch2\u003eTechnical Parameters\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency range\u003c\/td\u003e\n\u003ctd\u003e1 MHz ... 3 GHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasuring output\u003c\/td\u003e\n\u003ctd\u003e50 Ω, SMB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCorrection oscilloscope\u003c\/td\u003e\n\u003ctd\u003eE [V\/cm]: U\u003csub\u003eAV\u003c\/sub\u003e · 20 · 10\u003csup\u003e3\u003c\/sup\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCorrection oscilloscope\u003c\/td\u003e\n\u003ctd\u003edE\/dt [V\/cm · s]: 20 · 10\u003csup\u003e3\u003c\/sup\u003e · dU\u003csub\u003eAV\u003c\/sub\u003e \/ dt\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCorrection spectrum analyser\u003c\/td\u003e\n\u003ctd\u003eE [V\/cm]: U\u003csub\u003eAV\u003c\/sub\u003e + 86 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCorrection spectrum analyser\u003c\/td\u003e\n\u003ctd\u003edE\/dt [V\/cm · s]: U\u003csub\u003eAV\u003c\/sub\u003e + 86 dB + 20 · log ω\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax.
