Model 6487 User's Manual
2 CHASSIS
This screw terminal is used to connect COMMON to CHASSIS ground via the ground link connector.
3 COMMON
This standard banana connector can be used as input LO or as the common for the ANALOG OUT.
Also can be used as a ground link. Note that there is a 1k(ohm) resistance to input LO from the
ANALOG OUT common.
4 ANALOG OUT
This standard banana connector provides a scaled, inverting output (inverting 2V full scale on all
ranges).
5 TRIGGER LINK
Eight-pin micro-DIN connector for sending and receiving trigger pulses among connected instru-
ments. Use a trigger link cable or adapter, such as Models 8501-1, 8501-2, 8502, and 8503.
6 DIGITAL I/O
Male DB-9 connector for digital output lines and component handler signals.
7 RS-232
Female DB-9 connector for RS-232 operation. Use a straight-through (not null modem) DB-9 shielded
cable.
8 IEEE-488
Connector for IEEE-488 (GPIB) operation. Use a shielded cable, such as Models 7007-1 and 7007-2.
9 V-SOURCE OUTPUT HI
This standard banana connector provides HI connection to the 6487's voltage source.
WARNING
CAUTION
10 V-SOURCE OUTPUT LO
This standard banana connector provides LO connection to the 6487's voltage source.
CAUTION
11 INTERLOCK
This interlock connector provides connection of the 6487's voltage source with an interlock connector
on a test fixture.
12 Power Module
Contains the AC line receptacle and power line fuse. The instrument can be configured for line volt-
ages of 115V and 230VAC (nominal) at line frequencies of 50 or 60Hz automatically and over the bus.
Changing line voltages requires changing fuses.
Hazardous voltage may be present on the rear panel V-SOURCE
OUTPUT terminals when the front panel operate indicator is on.
Do not connect external sources to the 6487 voltage source. External
sources may damage the 6487 voltage source.
Do not connect external sources to the 6487 voltage source. External
sources may damage the 6487 voltage source.
