Tektronix Keithley 2601B-PULSE Reference Manual

Section 9: Introduction to TSP operation Model 2601B-PULSE System SourceMeter Instrument Reference Manual

For basic information about navigation and directory listing of files on a flash drive, see File system
navigation (on page 3-29).
File descriptor commands for file I/O use a colon (:) to separate the command parts rather than a
period (.), like the io commands.
File descriptors cannot be passed between nodes in a TSP-Link
®
system, so the io.open(),
fileVar::read(), and fileVar::write commands are not accessible to the TSP-Link system.
However, the default input and output files mentioned above allow for the execution of many file I/O
operations without any reference to a file descriptor.
