...4 CONFIGURATION

4.5.6 Archiving

Introduction
Recorded data, logs and configuration files stored in the instrument's internal memory can be archived to files created in removable
media in either text or binary encoded format. Parameters for archiving Process Group 1 are set up independently from Process
Group 2 parameters.
For a full description of archiving and archive file formats, refer to Sections 3.4 to 3.9.
Sample Rates – Fig. 4.9
With Basic configuration selected, data is saved to the archive file at the same rate as it is saved to internal memory, i.e. at either the
Group's primary or secondary recording sample rate.
With Advanced configuration selected, the sample rate for archiving is set independently of the recording channel sample rates that
are used for saving the data to internal memory. The archive primary and secondary sample rates can be linked to an internal
recording channel so that when that channel is switched between primary and secondary sample rate the archive sample rate is also
switched between the archive primary sample rate and the archive secondary sample rate.
