The best quality budget oscilloscope: Compared with the previous mini oscilloscope, this upgraded version of the 154PRO mini oscilloscope has a real -time sampling rate of 40msa/s, the bandwidth is 18MHz, and the 500kHz signal generator frequency.154Pro is a good choice.If you are excluding the old 8 -bit computer failure, the frequency band is very important.It matches the frequency level of retro computers. Built -in signal generator: Various waveforms with 3V amplitude such as sine waves, Fang waves, semi -waves, and triangular waves.You can move or zoom in the waveform of the trigger stop.The frequency is 0-500kHz, the duty ratio is 1-99%, and the output impedance value of the internal function generator is 150 ohm.There is a buffer amplifier in the output of the generator. Full trigger mode and one -click automatic: Small oscilloscope kit is equipped with 3 triggers, automatic/normal/single.Support waveform parameter settings, such as time benchmark, amplitude, etc.Support waveform one -click automatic adaptation screen without adjusting parameters, convenient and accurate measurement. Portable and powerful: This is a compact, compact, portable oscilloscope.The 154Pro range is matched with ARM and FPGA chips to provide high -speed signal acquisition and high -speed data processing. Wide application: can be used for SIN--Chip debugging, car maintenance, home appliance maintenance, DIY debugging, e-competition, power debugging, inverter, etc. Colour:As Shown Material:plastic Package Contents: 1 set x handheld oscilloscope Only the above package content, other products are not included.
