Product Details:

NI PCI-4070 is a 6.5-digit FlexDMM PCI digital multimeter integrating high precision DMM and isolated digitizer functions, and this flexdmm pci digital multimeter can switch between stable multi-parameter static measurement and high-speed waveform acquisition, which greatly reduces the number of instruments required for automated test systems. It supports AC/DC voltage, AC/DC current, 2-wire and 4-wire resistance, frequency and period measurement, as well as diode test. Under digitizer mode, it can capture continuous waveforms up to 1.8 MS/s with isolation protection, suitable for transient signal capture that ordinary DMMs cannot complete. It is widely used for aerospace component testing, power supply transient characteristic verification, circuit board functional test, sensor dynamic signal recording, laboratory metrology calibration and high-performance ATE system construction. Engineers can develop test programs with LabVIEW and NI-DMM driver, adjust reading rate and acquisition mode, and use RTSI bus to synchronize with DAQ and switch cards to complete reliable rtsi synchronized measurement tasks.

Key specifications and parameters: 6.5-digit resolution, basic DC voltage accuracy 25 ppm. DC voltage range ±300 V, AC voltage up to 300 V rms, DC and AC current up to 1 A. Resistance measurement supports 2-wire and 4-wire modes, resistance range up to 100 MΩ. Isolated digitizer sampling rate up to 1.8 MS/s. Standard PCI bus interface, front panel banana jack terminals for test probe connection. It supports external trigger and RTSI timing synchronization with other NI modular instruments. Rated accuracy is guaranteed within 15 ℃ to 35 ℃, storage temperature -20 ℃ to 70 ℃, 10%–90% non-condensing humidity. It needs sufficient warm-up time to reach full accuracy. Status LEDs display measurement status and trigger signal for convenient commissioning and fault checking. This model is discontinued, supplied as calibrated refurbished unit.

This high speed waveform capture card is a high-performance NI test hardware. We supply fully inspected and calibrated refurbished units for replacement and upgrade of precision automated measurement systems. It can be matched with relay matrix and signal conditioning modules to build multi-channel scanning test platforms. It is widely adopted in aerospace manufacturing workshops, power electronics test benches, university precision measurement labs and high-end electronic product verification projects. As a composite DMM with built-in digitizer, it provides both static precision measurement and dynamic waveform acquisition for complex automated test applications.
