Keithley 3720-ST User Manual

Section 9: Introduction to TSP operation Series 3700A System Switch/Multimeter Reference Manual
9-28 3700AS-901-01 Rev. D/June 2018
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.
