This topic shows the configurations that can be used for controlling Infiniium 2026.

From a remote computer, you can control Infiniium 2026 running on an oscilloscope or running offline on a PC. Because the oscilloscope is also a PC, you can also run programs on the oscilloscope or on the PC running Infiniium 2026 offline.

For example scripts for different configurations, see:

- Basic Script
- Simulated Instrument Install
