Agilent Technologies Inc. recently introduced a compact network analyzer, the Agilent E5061B, which analyzes a frequency range as low as 5 Hz up to the RF (radio frequency) range of 3 GHz. This network analyzer's broad range and versatility eliminates the need for additional low-frequency-dedicated instruments. Applications for the Agilent E5061B, part of the ENA series of … [Read more...]
Field Probes Offer High Performance in Compact Size
Teseq Inc., a developer and provider of instrumentation and systems for EMC emission and immunity testing, now offers two new USB / RS232 electric field probes. The PMM EP-600 and EP-601 active broadband field probes benefit from a true spherical symmetrical dipole configuration. Sampling at a rate of 22 S/s to 0.03 S/s depending on filter settings, the probes’ 6 monopole … [Read more...]

LED Dimmer Power-Converter IC Offers Low EMI
iWatt, Inc., a digital power IC systems products and technology company recently announced the release of the iW3620 Digital Controller for LED lighting applications. The company says it is the industry’s first LED driver IC for 5-40W luminaires with primary side regulation that eliminates the need for an opto-coupler and related components thereby reducing bill-of-material … [Read more...]
MEMS Spread Spectrum Oscillators (2.0mm x 2.5mm)
Ecliptek Corporation expanded its EMS MEMS spread spectrum low EMI output surface mount oscillator, theEMS4 series. The EMS4, in a miniature 2.0mm x 2.5mm package, reduces EMI at the clock source instead of locations later down the clock stream, potentially eliminating the use of supplemental shielding enclosures and/or filtering components. This greatly reduces system costs … [Read more...]
Next-Generation Bus Converter with Integrated EMI Filter
Emerson Network Power recently enhanced its dc-dc bus converter portfolio with the release of the ATC250. The company says the high-density, dual-input converter offers board manufacturers a ruggedized, compact solution for generating on-board power in high-density AdvancedTCA® (ATCA®) environments and other space-constrained systems that typically employ distributed power … [Read more...]
