LabVIEW Tools for Digital Filter Design and Implementation
LabVIEW Digital Filter Design Toolkit
The LabVIEW Digital Filter Design Toolkit extends LabVIEW with functions and interactive tools for the design, analysis, and implementation of digital filters. New digital filter users can explore classical designs with the built-in interactive design tools, while experienced users can find a breadth of algorithms, filter topologies, and analysis tools for both fixed- and floating-point digital filters. For fixed-point filters, you can model quantization effects, optimize numeric representation/topology, and deploy the design on a digital signal processor or FPGA using automatically generated ANSI C or LabVIEW FPGA code.

Dual, Low Noise, Coaxial Cable Optimized
DCOAX
Very high precision, three-terminal capacitance measurements can be affected by the self-inductance of the test cables, mainly at higher capacitance values. Magnetically induced noise can also reduce the quality of measurements. The cable now offered by Andeen-Hagerling both minimizes these problems and provides a way to standardize the residual self-inductance.

Low PIM Coaxial Switch, DC to 4 GHz, SP6T
87106P
Low passive intermodulation (PIM) is crucial for applications where two or more transmitted signals share a common antenna or whenever the transmitter signal is too high or the receiver is sensitive to high intermodulation. The Keysight 87106P is a low PIM SP6T coaxial switch, operating from DC to 4 GHz, which can help to keep the system PIM level low. A guaranteed 0.03 dB insertion loss repeatability and 3 million cycles of operating life ensures signal integrity, improves testing efficiency, and ultimately maximizes test throughput.
