It is a DIY vector network analyzer. It features a 2.8-inch touch screen, 400mAh electricity for off-line application in 2 hours.
As for testing via TX/RX, you can get full set of parameters of S11 and S21. What you have to do is to replace the connection cables in the receiving and transmitting ports.
We have redesigned its PCB board. Designed with simple but practical PC control software, you can export Touchstone (snp) files for various radio design and simulation software through PC software.
Its improved frequency algorithm can support the measurement frequency of 900MHz with the odd harmonic extension of si5351.
Designed with a metal shield to reduce external interference and improve measurement accuracy, si5351 directly outputs frequency of 50K-300MHz with dynamics better than 70dB. Its expanded 300M-600MHz band can provide dynamics better than 50dB, and 600M-900M band with dynamics better than 40dB.
