COMPREHENSIVE
The Laplace range of LISNs covers an exceptionally wide scope, covering all applications from commercial and industrial to military , aerospace satellite.

COMPLIANCE
All Laplace LISNs are fully compliant with the appropriate standard and are shipped complete with calibration data.

PROTECTION
All standard CISPR16 LISNs are fitted with a transient limiter and include a separate pre-ampflier to give a 0dB insertion loss.

CONVENIENCE
Commercial LISN'S are fitted with standard mains outlets. Country-specific types can be specified at time of ordering. Single pole jack sockets are normally also included so that individual conductors can be connected.

When measuring EMC emissions conducted from the equipment-under-test (EUT) most standards specify a LISN (or artificial mains V-network) to couple the RF from the cable and to provide a repeatable impedance at the measured frequencies. All laplace LISN's fully comply with the relevant standards and feature a rigorous, individual calibration with hardcopy of results issued by a uk test laboratory.

General Specifcations
RF Output socket: 50 ohm, BNC for each line.
EUT line connections:

Additionally for 16A type, domestic mains outlet fitted. Specify UK, US, Schuko(Euro) or As/NZ type when ordering.

Termination impedance: Internal
Ground bond: Stud terminal on front panel.
Artificial hand output: All CISPR16 LISNs fitted (220pF || 510 ohms).
