Portable Phase Frequency Analyzer Sensitive 4in Touch Screen 1MHz to 290MHz for Hardware Oscillator

Feature: 1. Precise Measurement: The phase frequency analyser allows for highly accurate measurements of phase and frequency differences between two input signals, catering to a wide frequency range of 1 MHz to 290 MHz. 2. Digital Display and Storage: The frequency analyzer offers digital display of phase and frequency differences, charts these measurements against time, stores data on an inserted storage card, or can send phase measurements to a PC via a USB for further display and processing. 3. High Accuracy: The portable phase frequency analyzer boasts a phase and frequency measurement accuracy better than 1 e‑12 per second, with the maximum frequency difference dependent on the measurement time. 4. Portable and User Friendly: Powered by a battery and charged via a USB port, this multifunctional frequency analyzer is portable. Its 4inch touchscreen display makes it extraordinarily convenient to carry and operate. 5. Cost Effective Versatility: If you already own a NanoVNA‑H4, and there is no need for long term measurements via handheld frequency analyzer, you can use NanoVNA‑H4 to flash in the firmware and use it.
