TAS152

TAS 100 provides the mix of critical features required for thorough evaluation in a compact, easy-to-use package. Designers can dramatically reduce development testing time and costs. Manufacturers can detect and stop defective products before they reach the field. Product evaluators can select between data communications products based on real-life performance, not just the specification sheet.

TAS 100 Series Telephone Network Emulators are designed to work with other TAS products to provide complete solutions for testing modems, fax machines, and a host of other data communications equipment. The TAS 100GT Series Automatic Modem Test Systems provide a comprehensive, automatic solution for testing and evaluating virtually all types of modems, including V.34 and V.34+.
