National Instruments 778697-01 PXI Waveform Generator

The part number 778697-01 from National Instruments is the identifying part number for the PXI-5421 PXI Waveform Generator. This PXI waveform generator is a part of PXI Express (PXIe) platform, which offers high bandwidth and low latency for data transfer, making it ideal for applications requiring precise timing and synchronization. It features 1 analog output channels with a connector type of SMB jack and direct output path with a 16 bits DAC resolution. It also offers 43 MHz analog baseband bandwidth measured at –3 dB and an FIR digital interpolation filter with available interpolation factor of 2, 4 or 8.

This module has a typical power consumption and overload operation of 1.9 A and 2.7 A at +3.3 VDC, 2.0 A and 2.2 A at +5 VDC, 0.46 A 0.5 A at +12 VDC and 0.01 A 0.01 A at -12 VDC. Its total typical power is 21.9 W and 26.0 W overload operation power. The 778697-01 is compatible with the following software LabVIEW, LabWindows™/CVI™, Measurement Studio, Microsoft Visual C++ .NET, Microsoft Visual C/C++ and Microsoft Visual Basic.

The 778697-01 PXI Waveform Generator supports a variety of triggering and event capabilities, ensuring precise control over test execution. These triggers can be configured as start trigger edge, script trigger edge and level, software trigger. For start trigger its maximum input overload is –2 to +7 V with an input impedance of 1 kΩ while for the output event capabilities, its maximum output overload is also –2 to +7 V with an output impedance of 50 Ω and rise fall time of less than 2.0 ns. 

The waveform generator is designed to be intended for indoor use only and can be mounted at an altitude of 2000 meters with a pollution degree of 2. It is made to operate at an ambient temperature of 0 to 55 degrees Celsius and storage temperature of -25 to 85 degrees Celsius. Its operating humidity is 10% to 90%, noncondensing and its storage humidity range is 5% to 95%, noncondensing. It has operating shocks of 30 g, half-sine, 11 ms pulse that meets the IEC 60068-2-27 standard and operating vibrations of 5 to 500 Hz, 0.31 grms that meets the IEC 60068-2-64 standard.
