- Screen update change the rate of Viewport refresh and data transfer between Server and Viewports
- Demon and device priorities defines the priority of corresponding threads. The priority of GUI is always normal. Time critical priority is not recommended but can be used for software synchronization of sequences with high repetition rates.
- Single thread execution forces to execute demon and devices in the single thread. For single processor computers and high speed devices this option may increase SpecMan4EPR performance.
- Communication warning options generates a warning if device does not response in specified time.
- Arm to trigger delay insert a delay between acquisition device programming and sequence execution. May improve performance for slow acquisition devices. Negative number stands for now delay.
- Force sequence programming eliminates the optimization which skip programming of sequences when it is not required. Not recommended.
- Use data buffering stores the data of current scan into scan buffer (see also Viewport). Preservs experiment data when experiment is terminated in the middle of scan. Very recommended.
