The Cobalt C1220 is a modular computer controlled Vector Network Analyzer that operates from 100 kHz to 20 GHz. The analyzer efficiently handles advanced test applications, providing an unmatched price-performance combination for S-parameter measurement over its supported frequency range.
To achieve this high performance at an affordable cost, the design and production of Cobalt VNAs incorporates several innovative new proprietary manufacturing and test approaches. This technology allowed for new test grade coaxial connectors technology for internal interconnect and tighter tolerances that contribute to Cobalt’s exceptional metrological accuracy. Advanced electromagnetic modeling optimizes the 20 GHz Cobalt’s ultra-wideband directional coupler design, and new production methods for precision airstrip lines give the directional couplers extraordinary stability, both over temperature and very long time intervals.
Cobalt VNAs feature hybrid dual-core DSP+FPGA signal processing engines, and new frequency synthesizer technologies. This architecture enables high performance with measurement speeds of less than < 10 µs and a frequency setting resolution of 1 Hz. The VNA can be controlled by any Windows PC or laptop.
