Figure 1. Power Spectrum of a 10 MHz Sine Wave Output from the PXI-5421

The NI 5421 has four triggering modes for controlling the starting and stopping of waveform generation – single, continuous, stepped, and burst. With these triggering modes combined with the linking and looping flexibility of the NI 5421, you can create sophisticated waveforms. With the 256 MB memory configuration, more than 1 million waveforms can be stored in memory and linked in any order. Each waveform segment can be looped up to 16,777,216 times or looped indefinitely. Triggers can be received from software as well as the front panel connectors, PXI trigger lines, PXI star trigger, or RTSI bus. LVDS Digital Pattern Output In addition to generating analog signals, the 32 and 256 MB configurations of the NI 5421 can generate low-voltage differential signal (LVDS) digital patterns. LVDS is increasingly used for digital signaling because of its reduced power consumption, lower electromagnetic interference, and immunity to noise. The digital patterns generated on the digital data and control (DDC) front panel connector correspond to the analog waveform being generated and make use of all of the linking, looping, triggering, and timing features. The sample clock is also available on the DDC I/O connector to latch the digital patterns. Alternatively, you can externally clock the NI 5421 via the DDC front panel connector. The NI Digital Waveform Editor is available as an add-on software package to provide you with further functionality in creating LVDS digital patterns. Timing and Synchronization The NI 5421 sample clock has three modes – Divide-by-N, High- Resolution, and External. Using the Divide-by-N sample clock, the jitter of the analog output is <1.0 ps rms and the phase noise is -137 dBc/Hz (10 MHz carrier, 10 kHz offset). The direct digital synthesis (DDS) based high-resolution sample clock has a sample rate resolution of 1.06 µHz, which offers you exceptional stability and sampling rate flexibility. The NI 5421 can also import its sample clock from the CLK IN and DDC connectors, PXI star trigger, and PXI trigger bus or RTSI bus. In addition, you can phase lock the NI 5421 oscillator to an external reference or the PXI 10 MHz reference clock. With synchronization, you can create mixed-signal test systems by combining the NI 5421 with other modular instruments such as the NI 5122 digitizer and/or the NI 655x digital waveform generator/analyzer. You can also synchronize two or more NI 5421 modules to build a multichannel phase coherent AWG, important for applications such as I and Q signal generation or antilock brake system simulation. To trigger other instruments such as oscilloscopes, the NI 5421 can generate marker event outputs. A marker event can be placed in a different location in each waveform segment. Calibration Every NI 5421 is factory calibrated using NIST-traceable standards. The NI 5421 has an onboard calibration reference that corrects for environmental effects on DC gain, offset, and timing errors. If you want to calibrate your device externally, return your NI 5421 to National Instruments or ship it to a qualified metrology lab for recalibration. Software Every National Instruments signal generator comes with the IVI-compliant NI-FGEN driver, which is fully compatible with NI LabVIEW, LabWindows/CVI, and Measurement Studio, as well as Microsoft Visual C++ and Visual Basic. NI-FGEN also includes the interactive FGEN Soft Front Panel, with which you can quickly generate standard signals such as sine, square, and ramp, as well as user-defined waveforms. Simulation mode is available in both the FGEN Soft Front Panel and the NI-FGEN instrument driver, so you can develop your application without having the hardware in your system. In this mode, several developers can write applications for the same hardware and share resources. With the Analog Waveform Editor you can rapidly create or edit analog test signals for use with the NI 5421. T o view or edit existing waveforms, you can open files saved in binary, ASCII, or the LabVIEW Express .lvm file format. Alternatively, you can create your waveform from scratch by selecting from a list of over 20 waveform primitives, such as sine and Gaussian noise, or enter a mathematical expression. The Analog Waveform Editor is included with the 32 and

256 MB models of the NI 5421, and is a separate add-on for use with

the 8 MB model. 2 National Instruments • Tel: (800) 433-3488 • Fax: (512) 683-9300 • info@ni.com • ni.com NI PXI-5421 NI PCI-5421 Includes NI 5421 module, SMB112 cable, NI-FGEN, and FGEN Soft Front Panel.
