HTOOL-SA8T is a handheld RF tester integrating spectrum analysis, signal generation and S21 measurement, with all-metal body and touchscreen design. It supports markers, peak search, trace averaging, spectrogram, and can be controlled via PC software and SCPI commands, suitable for field testing, R&D debugging and system integration. Applications include S21 gain/loss testing of filters, amplifiers, cables and feeders, field spectrum monitoring and interference locating, signal source output and calibration, antenna and RF link checking, R&D and production debugging, automated test integration, and RF teaching experiments.
Frequency range: 13.5 MHz–8.2 GHz Spectrum analysis: noise floor as low as -120 dBm, RBW 2.5/5/10/25 kHz Signal source output: 13.5 MHz–6.4 GHz adjustable from -29 dBm to -11 dBm, 6.4–8.2 GHz fixed at -29 dBm S21 measurement: supported for device gain/loss evaluation Power & interfaces: 5000 mAh battery, Type-C and SMA interfaces, SCPI support
