Using Calibration to Optimize Performance in Crucial Measurements
EMC Test Software
The model SW1006 is the latest version of the company’s radiated susceptibility, conducted immunity and precompliance emissions software. Model SW1006 automatically performs both calibration and immunity testing in full compliance with IEC 61000-4-3, 4-6, MIL-STD 461/462 RS103, CS114, RTCA/DO160 Section 20 specifications. The software also supplies the user with selectable test parameters and a “thresholding” mode for pre-compliance investigation of equipment susceptibility, as well as closed loop leveling. Pre-compliance emission testing can be done with the use of a spectrum analyzer and either a pre-amp or LISN. The SW1006 software is designed for use with the supplied NI PCI-GPIB interface card for instrument communication.

Parametric Product Search Tool
The parametric product search tool is designed for the RF engineer to specify important product parameters and view the company’s products that match a specific requirement in a specification-compliance format. Unlike conventional search engines which eliminate products that narrowly fall outside of specification, the parametric product search tool can show these products allowing the engineer to make intelligent design trade-off decisions to “fine tune” the requirement to specific needs. View this and other product software support tools including Product Cross Reference, PLL Phase Noise and Mixer Spur Chart Calculators on the company’s site.

EM Design Software
Version 7 of the MicroStripes electromagnetic design simulation software for microwave and antenna design substantially increases the speed with which users can tune their designs. It automatically runs a series of simulations while varying one or more design parameters over a user-specified range. This feature is supplemented by improvements in the accuracy of the automatic meshing algorithm. Also, Version 7 enables users to inspect simulation results quickly by simply running the mouse over the graphical output. It uses the Transmission Line Matrix (TLM) method for solving Maxwell’s equations, which when applied to antenna design solves for all frequencies of interest in a single calculation, capturing the full broadband response of the system in one simulation cycle.
