In addition to Mr. Richards, which was all correct, the standard way to
provide 50 Ohms at both ends of the coax is to use a 10 or 20 dB pad at the
interrogated LISN EMI port.

Two academic questions for the group:
1. When we say '50uH/50 ohm LISN' are we referring to a device which
provides
a source impedance of 50 ohms over its frequency range or one that must be
terminated with 50 ohms?
2. Is it sufficient to terminate a cable in its characteristic

A recent poster asked about service manuals for a Chase GP4403 EMI Receiver.
Although I’m not at all familiar with Chase gear, a friend suggested that,
depending on the age, the Chase equipment might be re-badged Rohde Schwartz

FWIW.
