Test Equipment Description

Com-Power ISN-T2 Details:

The Com-Power ISN T2 is used for common-mode disturbance voltage measurements on ports with a single, unshielded, balanced pair for Cat. 3 or Cat. 5 cabled networks.

The RF input/output port is a 50Ω female BNC connector, located on the top of the ISN. The ISN is equipped with D-sub 25 pin female connectors located on the front and rear panels for connection to the LCL and connecting adapter, respectively. The LCL and connecting adapters are available with either RJ- 11 or RJ-45 connectors for connection to the EUT and AE. For non-standard pin arrangements, the ISN can also supplied with user-configurable LCL and connecting adapters which can be configured for any pin arrangement. The ISN and LCL adapters are individually tuned and calibrated to meet the applicable requirements of EN 55022 (CISPR 22) and CISPR 16-1-2. The calibration data and certificate are provided, with NIST traceability.
