Polar, Cits500s controlled impedance test system

Polar, Cits500s controlled impedance test system
Artikelnummer: 11099

The CITS500s Controlled is an impedance test system designed to provide low automated measurement of the resistance characteristic of boards and test coupons.

The resistance test system contains a measurement system controlled by software running in Microsoft Windows software on IBM PC-compatible computers.

The CITS500s is designed to facilitate quick and convenient testing of controlled impedance boards and coupon testing.

Communication between the CITS500s and the Board during the test is achieved with cables, sensors and a microstrip probe.

CITS SOFTWARE is written to run in a Microsoft Windows environment, so the waveform test results can be printed using a printer.

The CITS system can be controlled from a computer keyboard or with simple point-and-click operations with a Microsoft-compatible mouse. Use of the mouse is recommended for maximum convenience.

A footswitch plugin is included in CITS to allow the operator to perform testing.
