The test-house manager’s perspective continued: At well over a quarter of a million dollars just to replace the existing 26-1000MHz amplifier and the same again to cover 1-6GHz at 200W (will take two amplifiers), the test manager will need to justify half a million dollars for the amplifiers alone. And the total will likely rise to around $600,000 or more with other equipment … [Read more...]

Intersolar Europe
June 11-15, Munich, Germany To actively promote the development of solar technology. That was the aim set by members of the Working Group for Environmental Technology (Arbeitskreis für Umwelttechnologie) in Pforzheim when, in 1991, they organized a one-day event with presentations on the use of solar energy. Five solar companies presented their products there as part of a … [Read more...]
HEMP Immunity Test Methods for Equipment and Systems
IEC 61000-4-25:2001+A1:2012 describe immunity test levels and related test methods for electrical and electronic equipment and systems exposed to high-altitude electromagnetic pulse (HEMP) environments. Specifications for test equipment and instrumentation test set-up, test procedures, pass/fail criteria, and test documentation requirements are also defined by this standard. … [Read more...]
Companies Try to Create Room on Radio Spectrum
Cellphone carriers are concerned about running out of the radio spectrum that carries wireless calls and data; but companies are developing technology that could use radio frequencies more efficiently. A presidential advisory committee will present a report this month that explores ways in which computerized radio technologies could make better use of the spectrum. In a … [Read more...]
Random or Coherent Signals
In the previous post, I indicated that coupled Broadband energy levels are determined by whether the signals are random or coherent. Random/non-coherent signals originate from sources that are not time related. A couple of good examples would be receiver thermal noise and DC motor brush noise. Another would be the RF environment taken as a whole. Because the individual energy … [Read more...]
Lossless Wireless Communication Protocol
MicroStrain's new "lossless" wireless communication protocol supports scalable networks of high speed sensor nodes without data loss due to temporary radio frequency (RF) fading, multipath, or interference. This enables highly reliable data collection from scalable networks of wireless strain, acceleration, torque, force, and temperature to be collected without loss of … [Read more...]
