鍵盤頻率測試
按住某個鍵至少 3 秒鐘。
Advanced timing workspace
Measure repeat speed, delay, jitter, and stability
Choose a duration, start the test, then hold one letter key without releasing it.
What this result means
Accuracy note: this measures browser-visible key-repeat timing, not raw 125 Hz, 500 Hz, 1,000 Hz, or 8,000 Hz USB polling. Use repeated runs on the same computer to compare settings, browsers, or connection modes.
Ready
0.0 / 5.0 s
Select Start, then hold one letter key
Keep this area focused. Modifier keys and browser shortcuts are ignored.
Waiting for a clean run
For a useful comparison, collect at least 15 valid intervals and repeat the same duration two or three times.
Repeat interval timeline
Lower and flatter timing lines are more consistent. The orange line marks the median.
No interval samples collected.
Latest intervals
Newest valid repeat intervals from the active run.

鍵盤回報率相關測試：理解自動重複與 USB Hz
透過長按事件觀察瀏覽器計時，並了解它為何不能直接認證 USB 回報率。
長按重複事件受到作業系統控制；30–60Hz 一類結果不能用來否定鍵盤標示的 1000Hz USB 回報率。
