The FNIRSI DPOS350P puts four instruments in one 7-inch touchscreen tablet: a 350MHz, 1GSa/s two-channel oscilloscope, a 50MHz signal generator, a 200kHz–350MHz FFT spectrum analyzer and a 50MHz frequency response (Bode) analyzer.
It suits circuit debugging, EMI checks and filter tuning on the bench or in the field. The 8000mAh battery gives about 3 hours of use, charges over USB-C at 18W, and the inputs are protected to 400V.
