HTOOL-SA8T: 3-in-1 handheld spectrum analyzer + signal source + S21 vector measurement, 13.5MHz–8.2GHz.
On August 31, 2026, HTOOL launched the HTOOL-SA8T handheld RF test instrument. It integrates spectrum analysis, signal generation, and S21 transmission measurement, targeting RF R&D, filter/amplifier testing, university teaching, field spectrum inspection, and automated system integration.
Spectrum analysis: 13.5MHz–8.2GHz, max span 8186MHz, -120dBm noise floor, RBW 2.5/5/10/25kHz, 0.75s full-band sweep, 12GHz/s max sweep speed; input gain/attenuation +15/0/-15dB; 50Ω SMA.
Built-in signal source: 13.5MHz–8.2GHz; 13.5MHz–6.4GHz output -11 to -29dBm; 6.4GHz–8.2GHz fixed -29dBm.
S21 measurement: gain/insertion loss for filters, RF amplifiers, cables, passive devices; custom frequency points and through-normalization calibration.
Design: 125×75×20mm, 4-inch IPS touchscreen, 5000mAh battery (≥6.5h), dual SMA, CN/EN/RU UI.
