Sub-Millimeter Measurement systems Cobalt
Colbalt Fx is the first mmWave frequency solution that utilizes a 9GHz VNA. ColbaltFx's high dynamic range and directivity allow for highly accurate and stable millimeter-wave S-parameter measurements in three dedicated waveguide bands 50-75GHz, 60-90GHz, and 75-110GHz.CobaltFx offers an unparalled combination of price, performance, flexibility and size.
C4209, the VNA used in this system is from Copper Mountain Technologies industry leading Cobalt Series. It features fast sweep speeds down to 10 microseconds per point and a dynamic range if up to 160 dB, alll comprised in a compact, USB form factor. C4209 works seamlessly with Farran Technology's millitmeter-wave FEV frequency extenders.
The extenders are packaged in a small and versatile enclosures, that allow for flexible port arrangements with respect to the waveguide. Waveguide ports are manufactured in accordance to the new IEEE 1785 stanadard and ensure industrty best alignment and repeartability of the connection, allowing for long interval times between calibration. The system comes with a precision calibration kit, containing a flush short, offset piece and broadband load and allows for full 12-term port calibration.
