• USB-B connector
Connects to USB interface.
• Digital I/O connector
D-sub 25 pin female connector for general purpose I/O (GPIO). Can be used as
trigger input/output terminals or as an interface to a handler or the likes. For
details, see
“Using Digital I/O” on page 3-29
Pins 16 and 24 and pins 17 and 25 are reserved for the interlock function. If the
terminals are open, the instrument output is limited to 42 V. Be sure to connect
the terminals to the Agilent 16442B test fixture or another DUT interface before
performing measurements. If you do not use 16442B, you need to install an
interlock circuit. For details on how to install the interlock circuit, see
“Installing
the Interlock Circuit” on page 3-19.
WARNING Dangerous voltage of up to the maximum voltage of SMUs may be present at
the High Force, High Sense, and Guard terminals if the Interlock terminal is
closed.
NOTE Serial Number
You will need the instrument’s serial number when using the Agilent Technologies
telephone assistance program. The serial number label is attached to the bottom of
the instrument.
