ABSTRACT:
An LAN parameter measuring instrument is provided for measuring at least one physical parameter of a wired, packet based, baseband LAN. The instrument comprises input means for providing a connection to the LAN transmission medium to enable measurements to be made while the LAN is active and voltage measuring means arranged to connect to the LAN transmission medium through said input means and operative to measure the voltage on the LAN transmission medium during inter-packet gaps. The instrument may determine the resistance of the LAN by measuring the inter-packet voltage during the injection of a known current into the transmission medium.
