National Instruments has announced PCI versions of two high-speed and high-density digitizers/oscilloscopes, extending the company's high-speed PCI offering to 2GSps and low-cost PCI offering to $500 per channel.

The PCI-5152 general-purpose digitizer converts a desktop PC into a full-featured oscilloscope. It offers a 2GSps real-time sampling rate on one channel or a 1GSps real-time sampling rate on two simultaneous channels. For repetitive signals, the module features an ETS mode to sample at up to 20GSps. The board features 300MHz bandwidth and ranges from 100mV to 10V with 50 ohms and 1 megaohm software-selectable input impedance. Engineers can customize the PCI-5152 digitizer through software to perform user-defined measurements in application areas including semiconductor chip characterization, ultrasonic NDT, OCT and mass spectroscopy.

Starting at $500 per channel, the PCI-5105 eight-channel, 60MSps, 12bit DAQ board increases system channel density while lowering test costs. With ps-level synchronization accuracy among multiple modules, the device is suitable for building high-channel-count systems in application areas such as linear and phased-array ultrasonic NDT.

The NI-SCOPE driver, which is common to all NI digitizers, features more than 50 built-in measurement and analysis functions for time and frequency domain applications. Engineers can integrate the new digitizers with a variety of NI hardware including other digitizers, signal generators, high-speed digital I/O and multifunction DAQ devices to create custom measurement solutions. The PCI-5152 and PCI-5105 digitizers also work with all software including LabVIEW, LabWindows/CVI and NI TestStand as well as other common development environments such as C++, C# and .NET.
