Section 11: TSP command reference Series 3700A System Switch/Multimeter Reference Manual
11-254 3700AS-901-01 Rev. D/June 2018
Using this command removes the need to close a file after writing to it and allows it to be left open to
write more data. Data may be lost if the file is not closed or flushed before an application ends. To
prevent the loss of data if there is going to be a time delay before more data is written (and when you
want to keep the file open and not close it), flush the file after writing to it.
