Model 6485 and 6487 User’s Manual Getting Started 1-17
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 LO
This standard banana connector provides LO connection to the 6487’s voltage source.
WARNING Hazardous voltage may be present on the rear panel V-SOURCE
OUTPUT terminals when the front panel operate indicator is on.
CAUTION Do not connect external
sources to the 6487 voltage source. External
sources may damage the 6487 voltage source.
10 V-SOURCE OUTPUT HI
This standard banana connector provides HI connection to the 6487’s voltage source.
CAUTION Do not connect external sources to the 6487 voltage source. External
sources may damage the 6487 voltage source.
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 frequencie
s of 50 or 60Hz automatically and over the bus.
Changing line voltages requires changing fuses.
Voltage source
The Model 6487 voltage source can source up to ±505V DC and is used for the ohms
function. See “Basic connections to DUT,” page 2-5 in for full details on voltage source
operation.
