Polar products for impedance controlled PCBs

Polar products for impedance controlled PCBs are designed for OEMs and fabricators who are concerned with PCBs running in the popular 100MHz to 3GHz region, and specifically those where signal reflections rather than insertion loss is the main criteria from a signal integrity perspective.

Si8000m PCB controlled impedance field solver

The Si8000m controlled impedance field solver is the Polar field solver of choice for lossless PCB transmission lines operating at these frequencies. The Si8000m includes modelling to predict the finished impedance of multiple dielectric PCB builds and also takes into account  the local variations in dielectric constant on close spaced differential structures. The XFE option provides crosshatch return path modelling for flex and flex-rigid PCBs.

Speedstack PCB – Si8000m and Speedstack layer stackup design and documentation

The Si8000m is also sold as a bundle with Speedstack layer stackup design and documentation tool under the bundled name of Speedstack PCB. Speedstack is capable of interfacing with a range of CAD and PCB engineering systems either through proprietary links or the emerging IPC-2581 standard.

CGen PCB impedance coupon generator

Speedstack also links with CGen PCB impedance coupon generator for the semi-automated creation of impedance test coupons. CGen allows you to create a controlled impedance test coupon from scratch or import finished stacks from Speedstack PCB and Speedstack Si or structures from the Polar Si8000 and Si9000 field solvers.

CITS880/CITS880s controlled impedance test systems

Time proven CITS880 and CITS880s controlled impedance test systems complete the range of impedance controlled products. CITS880 will prove the base model for 80% of applications, CITS880s features leading edge capabilities for impedance test on finer line traces such as LPE (Launch Point Extrapolation). LPE offers better measurement of instantaneous impedance on fine line and thin copper traces, and in these situations offers better correlation with the lossless impedance results from field solvers such as the Si8000m.

Atlas PCB – Polar impedance test software for Tektronix DSA8300

A variant of the Atlas insertion loss test system also offers impedance test with LPE and may be considered as an alternate to the CITS should you be considering an imminent move to insertion loss testing.
