Instrument State and Cal Sets
The security level is always saved and recalled with an instrument
state. However, the instrument state may contain a Cal Set or
link to a Cal Set. Learn
more. This may influence the security level when the instrument
state is recalled. Here is how.
When a new Cal Set is created at the end of
a calibration, the current system security level is stored
with it. The only way
to change an existing Cal Set’s security level is by writing
a new calibration into the Cal Set. When later applied to a channel, if the Cal
Set has a higher security
level than the current system security level, the system security
level will become upgraded to that of the Cal Set. When saving an instrument state to either
a *.csa or *.cst file, the security levels of the system and
Cal Set are saved separately. When recalled, the higher security
level of the two is applied. To view the security level of a Cal Set, see
Cal Set Properties.
