TinyPFA Portable Phase Frequency Analyzer 1MHz-290MHz for Measurement of Deviation with 4-inch Touch Screen

TinyPFA Portable Phase Frequency Analyzer 1MHz-290MHz for Measurement of Deviation with 4-inch Touch Screen

Description:
- TinyPFA is a phase frequency analyzer that can accurately measure the frequency and phase difference between signals applied to two input terminals. The input frequency can be any frequency between 1 MHz and 290 MHz.
- A typical use is to measure the difference between two 10 MHz clocks. TinyPFA can display phase and frequency differences digitally, and display the relationship between measurement results and time in a graph. The measurement results can be stored on an SD card inserted into the SD card slot, or sent to a PC through USB, and programs such as TimeLab can be run for further display and processing. The phase and frequency measurement accuracy is better than 1e-12 per second.
- Please note that the maximum frequency difference that can be displayed depends on the measurement time (Tau), which is approximately 200Hz/s. Therefore, for Tau of 1s, the maximum frequency difference is 200Hz.
- TinyPFA is a portable battery powered device that uses a USB interface for charging and designed with a 4-inch display screen, making it very convenient to carry and operate.

Precaution:
- TinyPFA is based on the hardware of NanoVNA-H4 and runs customized software to measure small deviations between two signals with similar frequencies. If you already have NanoVNA-H4 and do not need tinyPFA for long-term measurement, you can use NanoVNA-H4 to brush in tinyPFA firmware and use it without the need for repeated purchases.
- TinyPFA is not a frequency meter and its internal reference is inaccurate and unstable. It is only used for measuring the deviation of two signals with similar frequencies. It can be used to compare a signal with a very accurate reference signal.
- TinyPFA is not a phase noise analyzer.
- TinyPFA is only available for specific users who require very precise frequency analysis. Please read the relevant instructions on tinydevices.org to confirm if it is suitable for your use. We do not provide usage guidance. If you are unsure of the purpose of tinyPFA, please do not purchase it.
