The National Instruments 780152-01, also known as the USB-4065, is a highly accurate digital multimeter with a resolution of six and a half digits, designed for versatile measurement applications. It effectively measures AC and DC voltage, AC and DC current, and resistance in both two-wire and four-wire configurations, making it suitable for a range of test and measurement scenarios in environments such as OEM applications and research facilities. This multimeter features a function change rate of 10 changes per second and an auto range time of 200 ms for resistance and DC voltage and current measurements, ensuring rapid and reliable data acquisition. It is characterized by a trigger delay of less than 1 µs and a maximum trigger rate of 2.5 kHz, providing quick access to precise measurements. The DC voltage input bias current remains below 40 pA at 23 °C, thus enhancing accuracy. It boasts second-order noise rejection for power-line frequencies of ±0.1% and an effective common-mode rejection ratio (CMRR) of over 150 dB. For AC measurements, the nominal input impedance is 10 MΩ in parallel with 200 pF, facilitating operations up to 250 V for DC voltage components and a Voltz-Hertz product of 3 x 10^7 V-Hz. The device also supports flexible trigger configurations, requiring a minimum pulse width of 200 ns and allowing for programmable edges sourced from the auxiliary I/O connector. Output triggers indicate Measurement Complete with a logic level of 3.3 V and a pulse width of 1 µs, further enhancing the utility of the USB-4065 in complex measurement setups.
