National Instruments PXI-4351 Digitizer
The National Instruments PXI-4351 (Part Number: 777790-01) is a High-Precision Digitizer. This model comes featured with a 24-Bit Sigma-Delta Analog-to-Digital Converter and has a low leakage construction. With this Digitizer, the user is able to take temperature measurements through thermistors, resistance temperature detectors (RTDs), ohm measurements using its integrated precision current sources, as well as current measurements utilizing external shunt resistors.
The National Instruments PXI-4351 can easily be used with a personal computer to make similar measurements possible with standard bench-top instruments like DMMs and data loggers. The 24-bit sigma-delta ADC it contains supports differential analog inputs. The NI PXI 4351 can be utilized for the measurement of resistance up to 15 kΩ, since it comes equipped with a built-in 1 mA precision current source. For monitoring TTL-level inputs, this Digitizer has programmable TTL-compatible digital I/O.
The NI PXI-4351 is Plug and Play compatible and fully software-calibrated. Since this model is compatible with a broad range of operating systems, the PXI-4351 allows the user to develop scalable applications across a variety of platforms. As far as its input characteristics are concerned, this model offers 14 thermocouple or 16 differential channels and its ADC resolution is 24 bits.
The low leakage construction of this Digitizer, along with its digital and analog filtering capability, provides excellent accuracy, noise rejection, and resolution. The National Instruments PXI-4351 supports software-programmable ground-referencing; thus, users can reference their floating signals without affecting voltage measurements even with ground-referenced floating signals. When used with a PC, the NI PXI-4351 performs as a cost-effective and versatile platform for high-resolution measurements.
