1. *DESIGN COMPATIBILITY*: This unit is designed to fit in original equipment while maintaining form and function. It features simple and convenient PC control software that allows users to export Touchstone (for Snp) files for various radio design and simulation applications. 2. *Enhanced Frequency Measurement*: The device has an improved frequency algorithm that takes advantage of the odd harmonic extension of the Si5351, allowing frequency measurements up to 1.5 GHz. The direct output for Si5351 covers a frequency range of 50 kHz to 300 MHz with a dynamic range of more than 70 dB, while the extended bands provide dynamic ranges of better than 60 dB for 300 MHz to 900 MHz and 40 dB for 900 MHz to 1.5 GHz. 3. *Dynamic Range Performance*: Specifically, the extended frequency bands provide dynamic performance: over 60 dB for the range from 300 MHz to 600 MHz and better than 50 dB for the range of 600 MHz to 900 MHz, ensuring reliable measurements across these frequencies. 4. *Quality Construction*: This product has connection threads that minimize connection points to respond faster to changes. In addition, stoneware PCBs are protected by silicone and provide resistance to temperature fluctuations and vehicle vibrations.
