Description
TinyPFA and NanoVNA-H4:
1.The hardware of the two device is the same, the different is the software and accessories.
2.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.
3.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 and 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 TinyDevices to confirm if it is suitable for your use. If you are unsure of the purpose of TinyPFA, please do not purchase it.
TinyPFA
What is the tinyPFA?
The tinyPFA is a Phase Frequency Analyzer, it is a portable, battery operated, two input device with a 4 inch display that can measure very precise frequency and phase differences between the signals applied to both inputs. The input frequency can be any frequency between 1 MHz and 300 MHz. Typical use is to measure the differences between two 10 MHz clocks. The tinyPFA can numerically display the phase and frequency difference, show the measurement in a graph versus time, store the measurements on a SD card inserted into an SD card slot, or send the phase measurements over USB to a PC, running a program such as TimeLab, for further display and processing. Phase and Frequency measurement accuracy is better then 1e-12 divided by the measurement time in seconds with decimation set to 1 Be aware the maximum frequency difference that can be display depends on the measurement time (Tau) and is approximately 200 Hz / (Tau in s) so for Tau is 1 s it is 200 Hz maximum difference

Here is a video demonstrating an earlier version of the software: https://youtu.be/1LOxep-1ai0
After getting both the HW and SW you need to load the SW onto the HW It is always possible to restore the nanoVNA-H4 back to its original state by loading one of the nanoVNA-H4 SW's
ATTENTION: The nanoVNA-H4 is only platform that can be converted into a Phase Frequency Analyzer. None of the other small VNA's can be used.
ATTENTION: The tinyPFA does not contain an internal high stability reference. It will only perform a high accuracy phase difference measurement between two input clocks.
