Multi-Mode Functionality:
Offers three operating modes:

• Manual Mode: Turn the knob to manually adjust signal width, allowing you to test servo response or motor acceleration smoothly.

• Neutral (Center) Mode: Sends a fixed neutral signal (~1500 µs) to center the servo, ideal for initial setup and alignment.

• Automatic Mode: Generates automatic swing signals to cycle the servo or motor back and forth for endurance or consistency testing.

Supports 1–3 Servos/ESCs Simultaneously:
Can test up to 3 servos or ESCs at once, making it ideal for comparing responses or checking multiple outputs.

Wide Signal Compatibility:
Generates standard PWM signals (1000–2000 µs pulse width), compatible with most analog and digital servos, as well as brushed or brushless ESCs.

Compact and Lightweight:
Small size and lightweight (usually ~8–15 g), making it easy to carry in a field tool kit or toolbox.

Simple User Interface:
Just plug in a power supply (via servo plug or BEC), connect your servo/ESC, and select the desired mode using the onboard button or switch.

Low Power Operation:
Operates from standard 4.8V–6V DC power, usually supplied from a battery, BEC, or RC receiver.

Great for Troubleshooting & Setup:
Essential for diagnosing servo issues, calibrating ESC throttle ranges, or performing quick checks during assembly and maintenance of RC models.
