With its high sampling rate and low-distortion front end, an NI 5122 is ideal for a wide range of applications in automotive, communications, scientific research, military/ aerospace, and consumer electronics. Using the National Instruments Synchronization and Memory Core (SMC) architecture, you can easily synchronize to other analog and digital instruments to develop high-channel-count or mixed-signal test systems. Figure 1. Graph of Dynamic Performance (FFT) Analog Input Performance NI 5122 digitizers use 14-bit analog-to-digital converters (ADCs), low-noise variable-gain amplifiers, and a low-jitter 100 MHz timebase to deliver a 75 dBc spurious-free dynamic range and a 62 dB signal-tonoise ratio. The 14-bit data converters have 64 times the resolution of traditional 8-bit instruments, providing more accurate time- and frequency-domain measurements. Software-selectable 50 Ω or 1 MΩ input impedance, input ranges from 200 mVpp to 20 Vpp, seven trigger modes, and antialias and noise filters make NI 5122 digitizers versatile enough to meet the most demanding application requirements. The programmable DC offset feature maximizes the use of the entire 14 bits of vertical range. Onboard self-calibration also ensures measurement stability over the entire operating temperature range of 0 to 55 °C. Deep Onboard Acquisition Memory An NI 5122, based on the SMC architecture, comes with high-speed memory options from 8 to 512 MB per channel (4 to 256 million 14-bit samples per channel). An NI 5122 can acquire more than 1 million triggered waveforms without software intervention in multiple-record acquisition mode for applications such as RADAR, ultrasound, and event detection, which require short trigger rearm times. In addition, you can timestamp each triggered event with 100 ps resolution in both singleshot and multiple-record acquisition modes. An NI 5122 also can stream data continuously from onboard memory to host memory for longer acquisitions and streaming to disk. 100 MHz, 100 MS/s, 14-Bit Digitizer SMC (Synchronization and Memory Core) CH 0 50 Ω AC/DC Coupling 100/40/20 MHz Filter Stage -1 MΩ 100/40/20 MHz Filter Stage -1 MΩ Trigger and Event Control Timing and Synchronization Engine Gain and Offset Control 14-Bit ADC Gain and Offset Control 14-Bit ADC Onboard Memory (8 to 512 MB) PXI Bus NI-MITE (PCI Bus Interface) Onboard Memory (8 to 512 MB) Decimation Engine CH 1 50 Ω AC/DC Coupling EXT TRIG Clk OUT Clk IN AUX AC/DC Coupling PXI Trigger Bus Routing Matrix Figure 2. Hardware Block Diagram Data Streaming up to 400 MB/s Because of the PCI and PCI Express buses used in PXI, an NI 5122 can continuously stream data to the host computer at rates up to 110 MB/s using PCI/PXI or 400 MB/s using PXI Express. At 400 MB/s, an NI 5122 is streaming data on both channels at its maximum data rate. The dedicated per-slot bandwidth available in PXI Express enables multimodule systems to achieve higher aggregate data rates. High-speed data record and playback applications are possible using the host computer’s memory or high-end storage solutions such as RAID. Using an 8 x 500 GB drive RAID system with a capacity of 4 TB, you can capture data at 400 MB/s for more than 2.5 hours. Areas that benefit from this capability include RF/IF data streaming in signal intelligence, data record and playback, and scientific applications. directly from the device under test. Synchronize multiple instruments using the PXI backplane 10 MHz reference clock or an external reference ranging from 1 to 20 MHz in 1 MHz increments. Because an NI 5122 is built on the SMC architecture, you can synchronize two or more digitizers for high-channel-count applications and build mixed-signal test systems using NI PXI-5421 arbitrary waveform generators and NI PXI-655x digital waveform generator/analyzers. Software Every National Instruments high-speed digitizer comes with the IVI-compliant NI-SCOPE driver, which is fully compatible with NI LabVIEW, LabWindows/CVI, and Measurement Studio for Visual Studio 6.0 and .NET. NI-SCOPE includes more than 50 built-in measurement and analysis functions and an interactive SCOPE Soft Front Panel. The NI Spectral Measurements Toolkit gives you sophisticated frequencydomain measurements, such as power in-band, multiple peak search, and 3D spectrogram, for applications in communications, signal intelligence, and avionics. Triggering NI 5122 digitizers have three trigger sources – analog, digital, and software control. Compare the input signal on either channel or the external trigger channel to one or two thresholds for edge, hysteresis, or window trigger detection. You can also use line-selectable video triggering for NTSC, PAL, or SECAM broadcast standards. Drive and receive digital triggers to and from the PXI trigger bus or the external 9-pin AUX connector. You can specify the number of samples to acquire before and after a trigger event occurs. These pretrigger and posttrigger settings also apply when the module is used in multiple-record mode. Timing and Synchronization An advanced 100 MHz clock generator produces the low-jitter, low-phaseskew clock for the precise clocking and stable synchronization necessary for high-speed, high-resolution digitizers. You can also use an external clock source, such as the NI PXI-5404 100 MHz frequency generator, for applications that require very specific sample frequencies or you can clock Figure 3.
