5uH LISN/AN - Rent CISPR 25 & MIL-STD-461 CE Equipment
CISPR 25 Ed.4 (purchase standard) places specific requirements above the 60 Volt threshold, now categorizing ANs/LISNs as HV or LV. These new criteria are designed for electric or hybrid vehicles and typically edition 3 compliant V-LISNs are not compliant to HV design requirements.
The high voltage compliant ANs often include a shielded box or enclosure that as specified by section E.3 as seen with SME HV-AN 150 and HVSE 8600. Transient Specialists provides the enclosures with all rentals of CISPR 25 LISNs ensure that HV requirements are met.
MIL-STD-461G allows for 5uH LISNs to be used for both for CE101 and CE102 testing under associated discussions in appendix A. This allows for some 5uH LISNs/ANs (if they meet design requirements) to be used for both conducted emissions test.
The 10uF capacitor is required for compliance is typically done externally and is included for rental LISNs/AN. These can be an external boxes one per line, or simply put across connections as with the HV-AN 150.
Surge wave generators provide the necessary waveforms to simulate over-voltages from switching and lightning transients for a variety of EUT/DUT. This common immunity test is often based upon the product related pulse requirements, often around EN/IEC 61000-4-5 and other international and product based standards. One of the most common EMI surges focuses around combination wave pulses, different current and voltage waveforms simultaneously, or combined. Pulses associated with surges can generally be divided into a few categories by surges waveforms in current, voltage, or both. Below you will find pulses from the Teseq NSG 3040 designed for compliance to IEC 61000-4-5.
General Equipment Requirements
Injection Equipment/CDN if applicable
Unique standard or product requirements
Coupling or injecting pulses pulses onto different lines is primary done through CDNs or Clamps, unless the direct injection method is used. Often times coupling decoupling networks (CDNs). These methods are most often used for commercial testing given the wide range of power supplies and cabling.
