1 IEEE-488
Connector for IEEE-488 (GPIB) operation. Use a shielded cable, such as the Model
7007-1 or 7007-2.
2 OUTPUT
3-lug female triax connector for current source output. Mates to the supplied triax cable
(237-ALG-2). Will also mate to any triax cable terminated with a 3-slot male triax connec-
tor.
3 ETHERNET
RJ45 female connector for Ethernet operation. Use an RJ45 male/male cable for connec-
tion. Two status LEDs are located at the top of the connector. These LEDs indicate status
of the Ethernet (see Section 10 of the Reference Manual for details).
The rear panels of the Model 6220 and 6221 are the same, except the
Model 6220 does not have an Ethernet connector (3).
