Low Noise Accelerometer Cables & Coaxial Sensor Cables
-
Our cable assembly team in the UK produce the highest quality cable assemblies for use with a wide range of sensing and measurement applications. By making the cable assemblies in our own factory we are able to ensure the quality of every connection and every assembly, each cable is fully tested and its capacitance checked. Due to our experience in signal conditioning we understand the critical elements to quality signal analysis, this includes the correct cable. This is particularly true for accelerometer cables and sensors cables which can introduce significant noise issues if not used correctly.

Silicon Detectors
-
Through the photovoltaic effect, detectors provide a means of transforming light energy to an electrical current. The root of the theory behind this phenomenon is a small energy gap between the valence and conduction bands of the detector. When light, with enough energy to excite an electron from the valence to the conduction band, is incident upon the detector, the resulting accumulation of charge leads to a flow of current in an external circuit. Since light is not the only source of energy that can excite an electron, detectors will have some amount of current that is not representative of incident light. For example, fluctuations in thermal energy can easily be mistaken for light intensity changes. A variety of these "non-light" contributions are present and, when summed up, make up the total noise within the detector.

Proactive Downstream Spectrum Analysis
SpectraVizion
-
SpectraVizion is an innovative, software-based diagnostics tool that leverages new advancements in remote spectrum capture, allowing cable operators to address downstream spectrum impairments proactively, before subscribers call in with service complaints. “Troubleshooting downstream spectrum issues has always been a reactive process for cable operators,” said Arthur Skinner, Vice President of Worldwide Sales for ZCorum. “Often they’re not aware they have an issue until a customer calls, and that’s when they then send a technician to the home with a hand-held meter to start a search for the problem.” SpectraVizion takes the guesswork out of problem identification and location by presenting on a simple dashboard a list of devices that are experiencing common downstream issues like Standing Waves, FM Noise, Suck-outs, Roll-off and Tilt. The tool leverages the spectrum data available from cable modems and set-top boxes that support full band capture, and advanced detection algorithms automatically identify devices experiencing downstream impairments. The operator can click on any device in the list to view a capture of the full spectrum from that day, or up to 30 days in the past.
