The TinyPFA Portable Phase Frequency Analyzer is a precision instrument designed for measuring phase and frequency differences between two input signals with exceptional accuracy. Operating across 1 MHz to 300 MHz, it's ideal for clock synchronization testing, RF analysis, and precision frequency measurement applications. Built on NanoVNA-H4 hardware with specialized software, this portable analyzer delivers laboratory-grade performance in a handheld format.
Featuring a responsive 3.95-inch touchscreen display, the TinyPFA offers real-time numerical phase difference measurements and graphical analysis over time. Phase measurement accuracy exceeds 1e-12 per second, making it suitable for timing labs, metrology work, and 10MHz reference clock comparison. Connect via USB-C to export data to TimeLab or other analysis software for advanced signal processing.
Key Features & Specifications
- Frequency Range: 1 MHz – 300 MHz (two independent inputs)
- Phase/Frequency Accuracy: Better than 1e-12 per second measurement time
- Display: 3.95" TFT LCD touchscreen (320×240 resolution)
- Data Storage: MicroSD card support (up to 32GB) for long-term logging
- Connectivity: USB-C for PC data export, TimeLab software integration
- Battery: Built-in 2000 mAh rechargeable, portable operation
- Dimensions: 75 × 133 × 18 mm (compact field-ready form factor)
- Typical Applications: 10MHz clock comparison, frequency stability testing, phase measurement, precision timing analysis
Performance & Capabilities
The TinyPFA measures phase and frequency differences with precision that rivals bench-top analyzers at a fraction of the cost. Display maximum frequency differences depend on measurement time (Tau), approximately 200 Hz per second. Ideal for engineers and technicians requiring portable precision frequency analysis without expensive lab equipment.
Important Note
The TinyPFA internal reference is not high-accuracy, use only with external stable reference sources for best results. Perfect for comparing two reference clocks or signals with known stability characteristics.
