Gamepad Vibration Actuator Diagnostic

Trigger independent high-frequency (weak) and low-frequency (strong) haptic feedback motors to check rumble functionality.

Custom Vibration Intensity

5-Second Controller Latency & Polling Benchmark

Measures your controller's polling frequency over a 5-second sampling period. Rapidly wiggle both sticks or press buttons during the test for peak accuracy.

Polling Rate Reference Standards:
  • 1000 Hz (~1.0 ms): Overclocked DualShock 4 / DualSense, pro esports wireless.
  • 500 Hz (~2.0 ms): High-performance wired PC controllers.
  • 250 Hz (~4.0 ms): Standard DualSense / DualShock Bluetooth on PC.
  • 125 Hz (~8.0 ms): Standard Xbox Wireless Controller on Windows Bluetooth / USB.

Y B A X
3

Test every button

Every button lights up as you press it. If a button doesn't light up, it may be stuck or broken.

4

Rotate the joysticks

Spin both sticks in full circles, then let go. If a stick stays off-center, it has stick drift.

5

Run the vibration test

Trigger a quick shake or loop vibration to make sure the rumble motors work.

Key Diagnostic Features

🎯 Stick Drift Radar

See if your thumbsticks move on their own or fail to snap back to the center. Get live, exact coordinates down to 0.001.

🔄 Circularity Benchmark

Rotate your stick in a full circle to see if it reaches every edge smoothly without skipping corners or hitting flat spots.

📳 Dual Haptic Vibration

Test light buzzes and heavy rumble shakes separately to make sure your controller's vibration feedback is working.

⚡ Polling Rate & Latency

Test how fast your controller talks to your computer (speed in Hz and response time in milliseconds) with zero lag.

Hall Effect vs Traditional Potentiometer Joysticks

Modern controllers use two main types of thumbsticks. Here is how they work in simple terms:

Feature Traditional Potentiometers (Standard) Hall Effect Magnetic Sensors
How It Works Small metal parts rub against carbon tracks (wears down over time) Magnets detect movement without touching (never wears down)
Lifespan About 400 to 500 gaming hours Years of heavy daily gaming
Stick Drift Risk High (parts wear down and collect dust) Near Zero (no parts rub against each other)
Circularity Error 7% to 14% average 0.5% to 3.5% super accurate
Found In Standard PS5 DualSense, PS4, Xbox Series X|S, Switch Joy-Con 8BitDo Ultimate, GuliKit KK3, Flydigi Vader 4 Pro, GameSir G7 SE

Connection Speed: Wired vs 2.4GHz vs Bluetooth

How you plug in or pair your controller changes how fast it responds in games. Here is how different connections compare:

Connection Type Typical Speed (Hz) Delay (ms) Reliability
Direct USB Cable (Wired) 500 Hz – 1000 Hz 1.0 ms – 2.0 ms Fastest and most reliable; zero wireless interference
2.4GHz USB Wireless Adapter 500 Hz – 1000 Hz 1.5 ms – 2.5 ms Super fast and smooth; better than regular Bluetooth
Standard Bluetooth 125 Hz – 250 Hz 4.0 ms – 8.0 ms Great for casual games; can sometimes slow down if Wi-Fi is crowded

Troubleshooting: Why is My Controller Not Responding?

If your controller is connected via USB or Bluetooth but doesn't move on screen, try these quick fixes:

1. Steam Is Open in the Background
When Steam is running, its Steam Input feature often takes over your controller so you can use it like a mouse on your desktop. This prevents web browsers from reading your controller.

Quick Fix: Close Steam completely, or go to Steam > Settings > Controller > "Desktop Layout" and disable it while testing.
2. Test Inside Windows (joy.cpl)
You can also check your controller using Windows' built-in test tool: Press Win + R, type joy.cpl, and press Enter to open the Windows Game Controllers menu.
3. Press Any Button to Wake It Up
Web browsers (Chrome, Edge, Brave, Opera) wait until you press a button before sharing controller data to protect your privacy. Simply press A, B, X, Y, or a trigger. If using Brave, make sure Brave Shields is not blocking your device.

Step-by-Step: How to Test Your Gamepad

  1. Connect Your Controller: Plug your controller in using a USB cable or connect via Bluetooth in your computer or phone settings.
  2. Press Any Button: Press any button (such as A, B, X, Y) to wake up the tester.
  3. Watch Buttons Light Up: Every button you press will instantly light up on the screen. Triggers also show how far down you pull them (from 0.00 to 1.00).
  4. Check for Stick Drift: Let go of both thumbsticks. If the crosshair stays inside the green center circle, your controller has zero stick drift.
  5. Test Vibration & Speed: Use the tabs below to test rumble motors and benchmark your controller's speed and response time.

Frequently Asked Questions (FAQ)

❓ Why is my controller not detected when I plug it in?
Browsers keep your devices private until you press a button. Just tap any button (like A, B, X, Y, or the D-pad) after plugging it in, and your controller will appear instantly.
❓ What causes stick drift on controllers?
Stick drift happens when the small parts inside the thumbstick rub together and wear out from normal gaming. Dust, dirt, and pet hair can also get trapped inside. Newer controllers with Hall Effect magnetic sticks do not rub together, so they don't get stick drift.
❓ Can I test wireless Bluetooth controllers on PC or Mac?
Yes! Once paired to your computer's Bluetooth, modern operating systems recognize PlayStation, Xbox, and Switch controllers automatically. gamepad-tester.tech reads them immediately.
❓ How do I export a test report for warranty return or repair?
Click the "Export Report" tab below the visualizer and choose "Copy Log to Clipboard" or "Download Log File". You can paste this directly into support tickets for Sony, Microsoft, Nintendo, Amazon, or store returns.
