When the Agilent 16760A is operated in the 1250 Mb/s or 1500 Mb/s mode, only the even numbered channels are used. To reduce the number of probes and connectors required, the E5386A adapter maps the even channels to all of the pins of an E5378A, E5379A, E5387A, E5390A, E5405A, or E5406A probe. The E5386A half-channel adapter is usable with either the E5378A, E5390A, or E5406A single-ended probe or the E5379A, E5387A, or E5405A differential probe.
