Rohde & Schwarz demonstrated the use of coherent sources to make balanced device measurements, a nonstandard OFDM (orthogonal frequency-division multiplexing) modulation capability, and a group-delay measurement technique that doesn’t require local-oscillator access. It also, in conjunction with Noisecom, demonstrated
noise-figure measurements at 60 GHz
. Boonton, Noisecom’s Wireless Telecom Group sibling, introduced the 59318 peak power sensor, which is optimized for its 4540 and 4500B peak power meters.
Giga-tronics touted its 2500B series microwave signal generators, which cover the 100-kHz to 50-GHz frequency range and deliver a fast switching speed, typically less than 500 µs for a 1-GHz step. National Instruments demonstrated its NI Measurement Suite for Fixed WiMAX (IEEE 802.16-2004). Anritsu expanded its VectorStar VNA’s coverage to 110 GHz, introduced four-port test sets, debuted 18-GHz USB power sensors, and highlighted handheld VNAs that operate to 20 GHz.
Tektronix featured a range of products, addressing radio communications, spectrum management, radar, electronic warfare, amplifier characterization, and ultrawideband applications. It partnered with Mesuro to highlight nonlinear measurements. Aeroflex expanded its PXI test platform with the 3021C and 3026C RF signal generators, which offer +17-dBm outputs. Crystek highlighted its RFPRO (RF Pocket Reference Oscillator) series, which integrates a SAW (surface acoustic wave) oscillator in an SMA housing to deliver 500-MHz and 1-GHz outputs. Centellax previewed a 10-MHz to 50-GHz power amplifier. W.L. Gore announced that Richardson Electronics will sell Gore’s high-performance line of test and measurement microwave/RF cable assemblies.
