Configuration lists
Instrument configuration
An instrument configuration is a collection of settings that can be applied to the instrument.
Active setting
At any given time, the instrument is operating using its active settings. For example, if you set the
measure NPLC to 1.0, the active NPLC setting is 1.0.
Active state
At any given time, the complete set of active settings of the instrument is the active state. These
active settings can be divided into the following groups:
•
Measure settings
•
Source settings
•
General settings
The active state of the instrument changes when:
•
You use the front panel of the instrument to change settings.
•
You send commands to the instrument that change settings.
•
You use a configuration list to recall source or measure settings.
•
You run a configuration script (TSP or front panel) or use
*RCL
(SCPI) to recall all instrument
settings.
When you create a new source or measure configuration list, it is important to remember that all
instrument source or measure settings are included in its active state, not just the specific settings
that changed immediately before setting up the configuration list.
