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
. It is possible to gain an overview of proces
sor and memory utilization during data acquisition.
10.3 EWF, safeguarding your settings
against change
The program called EWF (

W
rite

ilter) 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‒R is next switched
on.
