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
measurement 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 subdivided into the following groups:
•
Measure settings
•
Source settings
•
All other 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.
What is a configuration list?
A configuration list is a list of stored settings for the source or measurement function. You can restore
these settings to change the active state of the instrument.
Configuration lists allow you to record the function settings of the instrument, store them, and then
return the instrument to those settings as needed.
You can recall configuration lists from the front panel, using remote commands, or as part of a trigger
model.
The following figure shows an example of a three-point source configuration list. Where:
•
Each tab represents a configuration list
•
Each row represents a configuration point
•
Each column holds the stored setting corresponding to that configuration point.
