VNA6 (1MHz–6.3GHz, 50dB S11 / 65dB S21 dynamic range) provides Smith chart, VSWR, group delay and more at a thousand-yuan price point. Students can complete calibration and first measurement in 30 minutes, suitable for antenna impedance tuning, filter insertion loss and other basic experiments. STB-R1/R2 signal integrity test boards use pure passive PCB to simulate transmission lines, differential pairs, via transitions, crosstalk coupling etc. Pair with VNA6 to directly observe S-parameter changes, turning abstract concepts like "impedance discontinuity" and "crosstalk" into visible curves, enabling SI intro experiments without custom PCB design.

SDR6 software defined radio receiver (RTL2832U core, wideband) paired with Gqrx software demonstrates signal reception, demodulation and audio output chains in the lab, suitable for communication engineering / electronic info RF principle demos and entry-level R&D.

SA8T's 3-in-1 capability (spectrum + signal source + S21) builds a teaching station where one instrument covers multiple experiments: spectrum analysis to observe signals, built-in signal source for excitation, S21 mode for filter/cable transmission tests, reducing multi-instrument procurement and maintenance burden.
