• 【2.4 GHz Frequency Meter】: This device is built with Microchip's PIC16F648A and features a 2.4 GHz frequency meter. The utilization of this specific microcontroller provides a solid foundation for its functionality, enabling it to handle frequency measurement tasks with reliability and precision within the specified frequency range.
• 【Utilization of Temperature-Compensated Voltage Controlled】: It makes use of a temperature-compensated voltage controlled crystal oscillator (2.5 ppm VC-TCXO). This oscillator plays a crucial role in maintaining the stability and accuracy of the frequency measurement. With its ability to compensate for temperature variations, it ensures that the device can provide consistent and precise results even under different environmental conditions.
• 【Precise Time Algorithm】: The device incorporates a unique gate control mechanism along with a precise time algorithm (non-timed interrupt). This combination allows for more accurate and efficient control over the measurement process, optimizing the way in which the frequency is measured and processed, and contributing to the overall high precision of the device.
• 【Real-Time Display】: The gate (display refresh) time can be set to 0.01 seconds / 0.1 seconds / 1.0 seconds. This flexibility in the display refresh time enables real-time display of the frequency value. Users can choose the appropriate refresh rate according to their specific needs, whether they require quick updates for dynamic measurements or a slower refresh for more stable viewing.
• 【Three-Channel Frequency Measurement】: It features a single-ended input design that supports three-channel frequency measurement, namely the low channel, high channel, and Auto Channel. This design provides versatility in measuring different frequencies, allowing users to easily connect and measure various frequency sources through the different channels available, expanding the range of applications for the device.
