Measurement of frequency response and bandwidth of multimeter and its principle

1, 44/5-bit true rms multimeter, maximum display number: 49999; 2, industrial-grade design, national military standard GJB quality; 3. Ultra-wide frequency response range up to 200KHz, wide measurement range of capacitance and resistance, and more powerful function; 4. The basic DC accuracy is 0.025%, and the true root mean square measurement makes the data more accurate; 5. Equipped with USB interface, data transmission is more convenient. With FaithtechView software, it can realize the functions of trend drawing, data viewing, real-time observation, logic analysis, single-channel oscillograph function, harmonic analysis and so on. 6. It has the functions of measuring AC voltage, DC voltage, AC current, DC current, resistance, capacitance, diode, switching performance, frequency, temperature, duty ratio, pulse width, relative value, dBV, dBmV and conductance. 7. Fast, minimum and maximum modes can capture the instantaneous signal of 0.25ms very quickly; 8. Patented design: manual or automatic diode screening voltage setting;
