ISN-T8

Impedance Stabilization Network, 150 kHz–30 MHz — measures common-mode disturbance voltage on unshielded balanced telecom ports with up to four pairs.

Per CISPR 22 Figure D.3 / CISPR 32 Figure F.8 circuit topology — complies with CISPR 16-1-2, CISPR 22, and CISPR 32 for conducted telecom emissions.

D-sub 25-pin EUT and AE ports with RJ-45 or RJ-11 interface options — D-sub on the ISN mates to an external LCL adapter (EUT side) and connecting adapter (AE side), so one ISN serves multiple cable categories and connector styles.

Unshielded Ethernet ports on ITE and consumer electronics — PCs, network appliances, IP phones, set-top boxes, and access points with unshielded Cat. 5/5e/6 jacks.

Analog and digital telephony with multi-pair drops — key systems, PBX line cards, and 25-pair amphenol-style telephony connections.

Low-speed industrial and building-automation links — RS-485 / Modbus, BACnet MS/TP, and similar multi-pair unshielded balanced signaling.

50 Ω BNC RF port on top of network — direct mate to spectrum analyzer / EMI receiver during emissions scans.

800 mA per line / 1.6 A per pair, 100 V DC / 64 V AC line-to-ground — individually calibrated; pairs with the Com-Power SPA-900TG series spectrum analyzer / EMI receiver.
