Spreadtrum CFT Tool (Calibration & Final Test Tool) is a professional production-line utility developed by Spreadtrum (now Unisoc) for calibrating and testing smartphones powered by Unisoc chipsets. It is primarily used by manufacturers, repair centers, and authorized service providers to perform RF calibration, battery calibration, hardware verification, and final quality testing before devices leave the factory.
The tool helps ensure every device meets manufacturing standards by automatically tuning RF parameters, verifying calibration data, measuring power consumption, and performing comprehensive hardware tests. If you work with Unisoc-powered devices, you can download the latest version of the Spreadtrum CFT Tool for Windows using the links below.
Spreadtrum CFT (Calibration & Final Test) is a factory testing utility designed to calibrate and verify hardware components on Unisoc devices. It performs automatic radio frequency (RF) tuning, battery calibration, current consumption testing, and final performance verification according to industry standards.
Unlike firmware flashing tools such as Research Download Tool or Upgrade Download Tool, CFT is intended for calibration and production testing, ensuring that every hardware component functions correctly before a device is shipped or serviced.
Battery Calibration (ADC)
The tool performs automatic Battery ADC (Analog-to-Digital Converter) calibration to improve battery level accuracy and optimize power management.
Key benefits include:
- Automatic battery calibration
- Improved battery percentage accuracy
- Optimized charging performance
- Better power management
RF Parameter Calibration
Spreadtrum CFT automatically calibrates critical RF parameters to ensure stable network performance.
It supports calibration of:
- AFC (Automatic Frequency Control)
- APC (Automatic Power Control)
- AGC (Automatic Gain Control)
These calibrations help improve signal quality, transmission stability, and overall cellular performance.
The tool performs comprehensive RF testing based on 3GPP standards, including:
- TX Power
- Phase Error
- Spectrum Emission
- ACLR
- EVM
- Receiver Sensitivity
- RF Stability Verification
These tests help identify defective hardware before devices reach customers.
Current Consumption Testing
Spreadtrum CFT can measure device current in different operating states, including:
- Power Off
- Idle Mode
- Deep Sleep
- Charging Mode
This allows manufacturers to detect excessive power consumption and abnormal current leakage during production.
System Configuration and Automation
To improve manufacturing efficiency, CFT supports several automation features, including:
- Auto-start when a device is connected
- Multiple production line roles (CFT, FT Only, Antenna Test)
- Automated testing workflow
- Detailed log generation
- Handover configuration between production stations
These features make it suitable for high-volume production environments.
