1. Instrument command name. Signals the beginning of the command description and is followed
by a brief description of what the command does.
2. Type of command. Options are:
• Function. Function-based commands control actions or activities, but are not always directly related to
instrument operation. Function names are always followed by a set of parentheses, for example,
digio.writeport(15). If the function does not need a parameter, the parentheses set remains
empty., for example, exit().
• Attribute (R), (RW), or (W). Attribute-based commands set or read the characteristics of an instrument
feature or operation by defining a value. For example, a characteristic of a TSP-enabled instrument is
the model number (localnode.model); another characteristic is the number of errors in the error
queue (errorqueue.count). For many attributes, the defined value is a number or predefined
constant. Attributes can be read-only (R), read-write (RW), or write-only (W), and can be used as a
parameter of a function or assigned to another variable.
3. TSP-Link accessible. Yes or No; indicates whether or not the command can accessed through a
TSP-Link network.
4. Affected by. Commands or actions that have a direct effect on the instrument control command.
