National Instruments PXI-5112 PXI Digitizer

The NI PXI-5112 PXI Digitizer highlights profound onboard acquisition memory, wide analog bandwidth, and a substantial analog input range in a low-cost model. This model offers two part numbers: 777758-01 with 16 MB/channel and 777756-01 with 32 MB/channel. Since the NI PXI-5112 Digitizer depends on the rapid PCI bus, acquiring and processing expansive waveforms is considerably speedier than with equivalent GPIB-based instruments. Because of this enhanced transfer rate, the user can take estimations speedier and diminish general test time. The NI PXI-5112 has two analog input channels that acknowledge signals going from ±0.025 V to ±25 V, variable in 10 percent steps. Each channel highlights programmable DC offset up to 20 times the input range, depending on the range selected. Accessible AC coupling or DC offset expands the dynamic range of signals that the user can quantify. The user can also force a 20 MHz hardware bandwidth limit for each channel to expel undesirable high-recurrence noise from estimations.

The NI PXI-5112 Digitizer is outfitted with the NI-TIO ASIC, a state-of-the-art counter and timing I/O ASIC created by National Instruments. The NI-TIO digitizer timing motor gives time stamping of records to 2 ns precision for real-time sampling and 100 ps exactness for random-interleaved testing (RIS). Time stamping likewise works in different record procurement mode. With quick rearm times, the user can timestamp activated occasions for up to 130 days with 2 ns precision continuously inspecting mode.

Both analog channels have their own 100 MS/s, 8-bit analog-to-digital converter (ADC), so the user can acquire information at the same time on each channel, at rates from 100 MS/s to 1 S/s. With the NI PXI-5112 high-exactness timing hardware, the user can test repetitive signals at rates up to 2.5 GS/s.
