How to improve the speed of a logic analyzer
All of the factors in this table can affect the sampling speed of a logic analyzer.
| priority | cause of the problem | method of solution |
|---|---|---|
| 1 | USB contact resistance is too high | Replace the USB cable with a new one |
| 2 | Sampling rate issue with the computer USB port | Test on a different computer, we recommend the laptops ThinkPad, MacBook Air, MacBook Pro, and desktops from Lenovo. |
| 3 | This USB port’s speed is not good enough | Try using a different USB port on the current computer |
| 4 | The adapter interference is too high | Unplug the power adapter of the laptop computer and use battery power instead |
| 5 | software version issue | Alternate testing of software versions 1.2.40 and 2.3.47 |
