The National Instruments PXI-5112 PXI Digitizer is a sophisticated measurement device that features two analog input channels with a signal input range adjustable from ±0.025 V to ±25 V in 10 percent increments, and it comes in two distinct part numbers: 777758-01 with 16 MB per channel and 777756-01 with 32 MB per channel.
Each channel on the PXI-5112 can leverage a programmable DC offset, which can be set up to 20 times the input range based on the selected range. Additionally, the device offers AC coupling and a hardware bandwidth limit of 20 MHz per channel, allowing for versatile signal processing capabilities.
It incorporates the NI-TIO ASIC, a specialized counter and timing I/O ASIC, that delivers precise timing with 2 ns precision for real-time sampling and 100 ps precision for random-interleaved sampling (RIS).
The PXI-5112’s analog-to-digital conversion is carried out with an 8-bit ADC resolution, and it supports a wide range of sampling rates from 100 MS/s to 1 S/s, with the capability to sample repetitive signals at up to 2.5 GS/s. Connectivity options include 2 BNC female, 1 SMB female, and a 9-pin DIN I/O connector.
With physical dimensions of 3.9 x 6.3 inches, the PXI-5112 is designed to fit into compact spaces while providing robust performance in a recommended operating temperature range that commences at 0 °C.
