Timing Calibration

GSG units with the Timing Calibration Option (OPT-TIM) have an additional timing calibration file installed, named pps.cal.

Provided the option is enabled, you can access and modify this file via the StudioView File Manager (> Tools drop-down menu), or the Web UI under the menu item GSG FILES, or by using SCPI file management commands (see MMEMory:COPY).

Note: Restoring factory defaults on the unit will also reset this file to the factory default for the unit.
