SCSI CABLE TESTER

ST123 - Paralan Corp.

Continuity tests alone are not sufficient to qualify SCSI cable assemblies. Proper testing of SCSI cables must include a test for correct connection of twisted pairs and shielding. Continuity tests check only that wires are making connections on both ends of a cable.Twisted pairs in the cable must be matched with the correct SCSI signal pairs - otherwise, it is possible to have a SCSI signal (signal and ground pair) placed on wires that are not in the same physical twisted pair (see diagram at right). This will cause crosstalk with resultant SCSI errors.

Bi-Axial or Axial Averaging Extensometers

Model 3560

-

Jinan Testing Equipment IE Corporation

Model 3560 - Jinan Testing Equipment IE Corporation

This extensometer is ideally suited for testing anisotropic materials such as advanced composites as well as for general purpose tests like determining Poisson’s ratio. The Model 3560BIA uses a design unique to Epsilon, where the knife edges remain parallel during the displacement. This approach greatly reduces crosstalk between axes and allows use on round or flat specimens with equal ease. These extensometers are very easy to mount. Integral springs hold the unit on the test sample. The parallel multiple flexure design makes these units very durable.The Model 3560AVG reads axial strain only as a single averaged output. It may also be supplied with two independent outputs, one measurement from each side of the specimen. This set-up is most commonly required when an indication of specimen bending is desired. The second version, the Model 3560BIA, includes both the averaged axial strain and the transverse strain. Again, this may also be configured as dual independent axial readings, which results in a three channel extensometer.The Model 3560 extensometers are strain gaged devices, making them compatible with any electronics designed for strain gaged transducers. Most often they are connected to a test machine controller. The signal conditioning electronics for the extensometer is typically included with the test machine controller or may often be added. In this case the extensometer is shipped with the proper connector and wiring to plug directly into the electronics. For systems lacking the required electronics, Epsilon can provide a variety of solutions, allowing the extensometer output to be connected to data acquisition boards, chart recorders or other equipment.

Digital Audio Snake System

OmniSnake

En Technology

OmniSnake - En Technology

The OmniSnake consists of a Stage Box that converts microphone/line-level analog inputs to a multiplexed digital signal, and a companion Base Unit that de-multiplexes to provide individual outputs. Digitizing the analog audio at the source eliminates the potential for ground loops, noise interference and crosstalk. Each Stage Box has 8 inputs, and two Stage Boxes can be linked together via coax to form a combined 16 channels, which is carried over coaxial cable to the Base Unit.
