AQSD-25
Automated Measuring System for Cat 5 performance testing.
The AQSD-25 is an automated measuring system designed for qualifying tests on balanced pairs according to category 5. The wide frequency range from 1 MHz to 300 MHz fully covers CAT 5 specifications. A 25-port automated access switch is used to contact the bare ends of the pairs. The measurement of all relevant RF parameters of up to 25 pairs runs fully automatically without any manual interactions.

Extensive computer controlled calibration data processing ensures a high degree of accuracy and reproducibility avoiding time consuming calibration before or during a measurement sequence. With its high measurement speed, the AQSD-25 is the right tool for production testing, if high through-put and reliable measurement data are a must.
