Saving data on the Data Recorder
70 A3169-8.0 HBM: public CX22B / CX22B-W
As a rough guideline, data throughput should be calcu
lated in MByte/s. A signal (sample) can be calculated
with 8 bytes. The opportunity is also available to experi
mentally check whether the chosen configuration works.
Diagnostic options are available via the lower status bar
in catman, to gain an overview of processor and memory
utilization at the start of acquisition.
10.4 EWF, safeguarding your settings
against change
The program called EWF (Enhanced Write Filter) pre
vents the files on partition C: being (unintentionally)
changed or overwritten. This could happen, for example,
if the voltage supply fails and Windows is not properly
shut down. In this situation, the program always restores
the "previous" state when the CX22B‒W is next switched
on.
All the data or programs saved on C: are therefore only
stored temporarily, and are deleted again once the sys
tem is switched back on.
If you want to permanently save settings or programs on
C:, you must use Commit changes and reboot in the
start screen ("CX22Shell"). Changes will then be perma
nently applied and will also be available the next time you
restart the CX22B‒W.
