150 MHz, 200 MS/s, 12-Bit Digitizers

NI PXI-5124, NI PCI-5124


2 channels simultaneously sampled with 12-bit resolution 200 MS/s real-time sample rate and 4.0 GS/s random interleaved sampling 150 MHz bandwidth 200 mVpp to 20 Vpp input ranges	>75 dBc SFDR 8, 32, 256, or 512 MB of memory per channel Edge, window, hysteresis, video, and digital triggering with 50 ps timestamping

Overview

NI 5124 high-resolution digitizers feature two 200 MS/s simultaneously sampled input channels with 12-bit resolution, 150 MHz bandwidth, and up to 512 MB of memory per channel in a 3U PXI or PCI device. NI 5124 devices use the high-speed PCI bus and the scatter-gather bus mastering of the NI MITE ASIC to move data to the computer at speeds up to 100 times faster than traditional instrument interfaces, thereby dramatically decreasing overall test time. With the NI Synchronization and Memory Core (SMC) architecture of an NI 5124, you can create mixed-signal systems using signal generators and digital waveform generators/analyzers or build a high-channel-count digitizer system with subnanosecond synchronization between channels.

Support and Services

System Assurance Programs

NI system assurance programs are designed to make it even easier for you to own an NI system. These programs include configuration and deployment services for your NI PXI, CompactRIO, or Compact FieldPoint system. The NI Basic System Assurance Program provides a simple integration test and ensures that your system is delivered completely assembled in one box. When you configure your system with the NI Standard System Assurance Program, you can select from available NI system driver sets and application development environments to create customized, reorderable software configurations. Your system arrives fully assembled and tested in one box with your software preinstalled. When you order your system with the standard program, you also receive system-specific documentation including a bill of materials, an integration test report, a recommended maintenance plan, and frequently asked question documents. Finally, the standard program reduces the total cost of owning an NI system by providing three years of warranty coverage and calibration service. Use the online product advisors at ni.com/advisor to find a system assurance program to meet your needs.

Calibration

TClk Specifications

National Instruments TClk synchronization method and the NI-TClk driver are used to align the sample clocks on any number of SMC-based modules in a chassis. For more information about TClk synchronization, refer to the NI-TClk Synchronization Help, which is located within the NI High-Speed Digitizers Help.

Specifications are valid for any number of modules installed in one NI PXI-1042 chassis.
All parameters set to identical values for each SMC-based module.
Sample Clock set to200 MS/s and all filters are disabled.
For other configurations, including multichassis systems, contact NI Technical Support at ni.com/support.

Note Although you can use NI-TClk to synchronize nonidentical modules, these specifications apply only to synchronizing identical modules.

NI PCI-5124
Note To ensure that the NI PCI-5124 cools effectively, make sure that the chassis in which it is used has active cooling that provides at least some airflow across the PCI card cage. To maximize airflow and extend the life of the device, leave any adjacent PCI slots empty. Refer to the Maintain Forced Air Cooling Note to Users included in the NI PCI-5124 kit for important cooling information. The NI PCI-5124 is intended for indoor use only.
