Performance Considerations

The PathWave Advanced Power Application Suite can only connect up to10 instruments at a time. As described below, there are IO interface and computer resource limitations to keep in mind.

Limitations of Remote Instruments

The PathWave Advanced Power Application Suite operates best with instruments that are connected locally to the computer running the application. The Instruments that are connected via LAN from remote locations or on a slow LAN may experience degraded performance and intermittent disconnects. Remote IO server connections will also suffer from degraded performance since they introduce another computer to the IO pathway.

Connection Issues with USB 3.0

If you are using USB to connect to your instruments, make sure you are using USB 2.0 ports. At this time, you might experience connection integrity and performance issues with USB 3.0 (indicated by "SS" next to USB connector on computer).

Limitations of GPIB

IO operations over GPIB are by nature serial transactions and performance will possibly degrade to the slowest instrument if multiple instruments are sharing the same GPIB bus. If you are experiencing performance issues with GPIB, try using separate GPIB interfaces or consider moving your instruments to USB for higher performance.

Limitations Due to Computer Resources

The processing power and memory capacity of your computer will determine the number of simultaneous operations allowed without degrading overall performance. Operations that require significant computational power, such as IV Curve measurement with large Var 1/Var2/Repeat and fetching of large data arrays, will be most affected by your computer's resources.
