AR/RF Microwave Instrumentation Receives Accreditation From A2LA
AR RF Microwave Instrumentation is pleased to announce that its calibration lab has achieved accreditation to ISO 17025:2005 by the American Association for Laboratory Accreditation (A2LA). This important certification is the result of a thorough assessment and extensive review of AR’s quality management system and its competence to perform calibrations on many AR-designed and … [Read more...]
New Spectrum Analyzer Software Doubles Path Loss Tables
While not a sweeping update to the software, Spike 3.1.7 does bring quite a few changes to the table. Satisfying one of our most requested features, EMC Precompliance analysis mode now offers more configurable path loss tables—twice as many, in fact—for a total of 8. These tables are also stored in presets now, making the EMC experience even better. Since introducing the EMC … [Read more...]
New Low-Phase Noise Amplifiers Deliver High-Dynamic Range Performance
Pasternack, a leading provider of RF, microwave and millimeter wave products, has released a new line of low phase noise amplifiers that incorporate GaAs HBT MMIC semiconductor technology to deliver ultra-low phase noise performance over a wide dynamic range. These amplifiers can be used to help optimize the sensitivity and dynamic range of higher performing test, radar and … [Read more...]

New Easy-to-Use EMI Test Software
The R&S ELEKTRA EMI test software has been designed for easy and intuitive EMI measurements during product development. It supports EMI test receivers and spectrum analyzers from Rohde & Schwarz. Even development engineers or technicians who only occasionally use these instruments to measure electromagnetic interference are able to configure automated test sequences … [Read more...]
The Importance of Layout in ESD Suppressing Diodes
ESD protection of sensitive electronics via transient voltage suppression (TVS) diodes is becoming a common circuit technique across industries. Signal lines in a circuit that are accessible to humans by touch (such as USB, HDMI, etc.) require ESD protection on all sensitive signal lines that are input to some IC’s. Placement of the ESD protection diodes on the circuit board … [Read more...]
Measuring Common Mode Versus Differential Mode Conducted Emissions
When faced with excessive conducted emissions from switching power supplies, one of the first things to investigate and to determine the adequacy of is the power line filter. Line-powered switching supplies generally have both common mode and differential mode sections of the filter as shown in the generalized schematic in Figure 1. When using a line impedance … [Read more...]
