- Simple and practical PC control software that can export touchstone files (snp) for wireless design and simulation software via PC. - The improved frequency algorithm uses the odd harmonic extension of the si5351 to support measuring frequencies up to 900 MHz. - Metal shielding reduces external interference and improves measurement accuracy. - The 50535-300MHz frequency range of the si5351 direct output provides more than 70dB dynamics. - The extended 300M-600MHz band provides more than 60dB dynamics, and the 600M-900M band is better than 50dB dynamics. - Use scenarios: - RF module development and testing: export SNPs to run simulations and validate designs with compatible tools. - Laboratory measurement and education: characterize frequency response and dynamics up to 900 MHz. - Prototyping wireless systems: perform quick checks of performance across 300-900 MHz bands.
