Model 2651A High Power System SourceMeter® Instrument Reference Manual
Contains the AC line receptacle and power line fuse. The instrument can operate
on line voltages of 100 V to 240 V AC at line frequencies of 50 Hz or 60 Hz.
Connector for IEEE-488 (GPIB) operation. Use a shielded cable, such as the
IEEE-488
Keithley Instruments Model 7007-1 or Model 7007-2.
Use this RJ-45 connector to connect the instrument to the local area network.
!
LAN
This interface supports Auto-MDIX, so either a CAT-5 cross-over cable
(provided), or a normal CAT-5 straight-through cable (not provided) can be used.
Expansion interface that allows a Model 2651A and other TSP-enabled
instruments to trigger and communicate with each other. Use a category 5e or
higher LAN crossover cable (Keithley Instruments part number CA-180-3A).
Ground screw for connections to chassis ground.
Exhaust vent for the internal cooling fan. Keep the vent free of obstructions to
prevent overheating. Also see
This connector provides input/output connections for sense (S HI/S LO) and
S
guard (G). Connections are as follows:
G G G G HI
S LO = Sense LO
G = Guard
S HI = Sense HI
This connector provides HI/LO connection points for currents. Connections are
OUTPUT
LO HI
as follows:
LO = Input/Output LO
HI = Input/Output HI
Cooling vents (on page 2-7).
