Description TinyPFA 1MHz-300MHz Phase Frequency Analyzer w/ 4" Touch Screen Measures Frequency Phase Difference Description: tinyPFA is a phase frequency analyzer. It is a portable and battery-operated device with a 4-inch display. It measures the frequency and phase difference between signals applied to two inputs very accurately. The input frequency can be any frequency between 1MHz and 300MHz. A typical use is to measure the difference between two 10MHz clocks. tinyPFA can show phase and frequency differences numerically, and graphs show measurement results versus time. It can store measurement results on an SD card inserted into an SD card slot or send the phase measurement results to a PC via USB. It can run programs such as TimeLab for further display and processing. Phase and frequency measurement accuracy is better than 1e-12 per second. Note that the maximum frequency difference that can be displayed depends on the measurement time (Tau), which is approximately 200Hz/s. Therefore, for Tau is 1s, the maximum frequency difference is 200Hz. Attention: - The tinyPFA does not contain an internal high stability reference. It can only perform a high accuracy phase difference measurement between two input clocks.
