4.3 Preload / Unload Modes
4.3 Preload / Unload Modes
The X-Series platform supports many Modes. Each Mode that is loaded uses a
portion of the total available memory. At some point, this may result in insufficient
free memory. This can occur during a measurement, or when loading a new Mode. A
limited number of Modes can be loaded without impacting performance.
Preload / Unload Modes allows you to select and enable Modes to be preloaded at
startup, and to specify the default Power-On Mode.
The dialog includes the following controls:
–
"Power-On Mode" on page 1770
–
"Table of Modes" on page 1771
–
"Preload: Select All, Preload: Deselect All" on page 1771
–
"Move Up, Move Down" on page 1771
–
"Unload" on page 1771
Modes that are not preloaded may be loaded at runtime as needed, resources
permitting. However, note that loading more Modes increases memory
consumption and may adversely impact performance.
When a memory-full situation occurs, the instrument notifies you with the following
message:
Out of memory; Insufficient resources. Please save state if needed. You have
following options:
1. Open System Settings > Configure Preload Modes to unload unused Modes
2. Reconfigure preloaded Modes on the above dialog, close and restart the
analyzer SW
3. Close and restart the analyzer SW
Option 1 allows you to unload unused Modes and continue running the software,
without having to restart it.
The command :INSTrument:UNLoad <mode> provides equivalent functionality;
see "Unload" on page 1771.
4.3.1 Power-On Mode
Displays a list of licensed Modes. Use this control to change the factory default
Power-On Mode. The instrument will execute the selected Mode after power up.
Selecting the Power-On Mode here automatically enables that Mode for preloading.
