The Cobalt C1220 VNA represents the current top of the range in CMT's portfolio. It offers vector analysis across a frequency range of 100 kHz – 20 GHz, with a dynamic range of up to 145 dB. It measures forward and reverse S-parameters, S11, S12, S21, S22, enabling precise time-domain and frequency-domain representations with rectangular, polar, and Smith charts. It delivers high-performance key specs such as 1 Hz resolution, 10 µsec Tau per point, up to 500K points, and output power adjustment in steps across 70 dB, among others. The C1220 analyzer covers a frequency range of 100 kHz to 20 GHz, offers a typical dynamic range of 145 dB, and is designed to run on any Windows PC or laptop. It efficiently handles advanced test applications, delivering an unmatched price-performance combination for S-parameter measurement in this frequency range.
To achieve this high performance at an affordable cost, the design and production of the Cobalt VNA incorporates several innovative new patented manufacturing and test methods. This technology enabled a new test-grade coaxial connector technology for internal interconnection and tighter tolerances that contribute to Cobalt's exceptional metrological accuracy. Advanced electromagnetic modeling optimizes the design of Cobalt's 20 GHz broadband directional coupler, and new production methods for precision air lines give the directional couplers extraordinary stability, both with temperature and over very long time intervals.
Cobalt VNAs also feature dual-core DSP + FPGA hybrid signal processing engines and new frequency synthesizer technologies. These advances drive Cobalt's measurement speed among the most advanced instruments in the industry and outperform the achievements of any cost-competitive product.
