Product Introduction
The NI PXIe-6358 is a high-performance, simultaneous-sampling X Series multifunction data acquisition module designed for high-speed automated testing, transient recording, signal analysis, and synchronized measurement applications. It combines analog input, analog output, digital I/O, counter/timer functions, and advanced triggering in a single PXI Express module.
With 16 differential analog input channels sampling simultaneously at up to 1.25 MS/s per channel, the PXIe-6358 can acquire time-correlated signals without the channel-to-channel delay associated with multiplexed acquisition systems. Its PXI Express interface and NI-STC3 timing architecture make it suitable for demanding multichannel measurement and control platforms.
Product Overview
The PXIe-6358 belongs to the NI X Series multifunction DAQ family and is optimized for applications requiring high-speed, phase-aligned acquisition across multiple analog channels. Each analog input channel uses dedicated simultaneous-sampling architecture, making the module suitable for transient signals, waveform comparison, phase measurement, and multichannel signal analysis.
In addition to its analog input subsystem, the PXIe-6358 provides four high-speed analog outputs, 48 programmable digital I/O lines, four 32-bit counters, and analog and digital triggering capabilities. These integrated functions allow engineers to perform acquisition, waveform generation, device control, event counting, and synchronization with one modular instrument.
The module is supported by NI-DAQmx and integrates with LabVIEW, TestStand, FlexLogger, and common programming environments, helping engineers develop scalable automated test and measurement systems.
