Retrieving and Restoring Data

This chapter shows you how to:

•

Copy ASCII measurement data.

•

Copy raw measurement data.

•

Restore raw measurement data.

•

Strip LIF structure from raw measurement data.

•

Copy screen images from

\system\graphics

•

Copy status information from

\status

•

Copy configurations from the logic analyzer.

•

Restore configurations to the logic analyzer.

Measurement data is available in binary format and also in ASCII
format for some measurement modules. Screen images are available
in TIFF, PCX, and Encapsulated PostScript



formats.
