Details
The conpin command is used to make connections in the S530/S540 systems. The S530
high-voltage system and the S540 3-kV system have two kinds of pins: High-voltage and low-voltage
pins. For the S530 system, the high-voltage (1100 V) pins are pin 1 and pin 2; the rest of the pins are
low-voltage (1100 V) pins. For the S540 system, pins 1 through 12 are high-voltage (3 kV) pins, and
the rest of the pins are low-voltage (100 V) pins.
The S540 contains interconnect pathways that allow 200 V source-measure units (SMUs) to connect
to the 3-kV pins in a protected circuit. The conpin command recognizes this and allows such
connections.
When used with an I-V matrix, the conpin command connects every item in the argument list
together. Because I-V connections do not require pathways to be allocated, a pin or terminal may be
used in more than one conpin command call. If there are no connection rules violated, the pin or
terminal is connected to the additional items and everything to which it is already connected.
High-voltage systems only: If you want to use high-voltage SMUs and low-voltage SMUs
simultaneously, connect the high-voltage SMUs first using the conpin command. This is important
because the source-measure units (SMUs) are connected starting with pathway A, and only
pathways A and B are high-voltage pathways. If you try to connect a high-voltage SMU using a
low-voltage pathway (for example, connecting a 2410 using pathway C in an S530 system), an error
is generated.
The first conpin or conpth command after any other LPT library call clears all sources by calling the
devclr command, and then clears all matrix connections by calling clrcon command before
making the new connections.
The value -1 is ignored by the conpin command and is considered a valid entry in the connection
list. However, there must be at least two entries in the list with a value other than -1.
Matrix errors are generated under the following conditions:
•
A dangerous connection is detected, such as connecting a source-measure unit (SMU) high
terminal directly to ground.
•
The user attempts to connect a high-voltage SMU to a 200 V pin, which is not allowed.
