Mohr adds Internet streaming to TDR cable testers

Test Measurement World Staff - May 1, 2009

Mohr and Associates has introduced software upgrades for its CT100 series RF/microwave TDR (time-domain reflectometer) cable testers and bundled CT Viewer host PC software. The upgrades add real-time Internet streaming and remote control to allow users to leverage remote engineering expertise. The upgrade also allows CT Viewer to remotely store and replay TDR waveforms at more than 250 fps, allowing the operator to capture and analyze transient impedances remotely.

Although existing CT100 series TDRs already store TDR trace data at up to 500 fps, the software upgrade gives CT Viewer the ability to store and replay TDR waveforms over a network connection in the form of AVI videos at frame rates of more than 250 fps. The company reports that the new upgrade is suitable for analyzing intermittent cable faults, quantifying real-time switch and button performance, and exploring TDR-based geophysical sensor techniques.

The instruments offer system rise times as low as 60 ps (20% to 80%) and cursor resolution of 75 microns. The company targets the CT100 as a replacement for the discontinued Tektronix 1502C metallic TDR.

Base price: $13,500. Mohr and Associates, www.mohr-engineering.com.
