National Instruments 778953-01 PXI Digital Waveform Instrument.
The part number 778953-01 from National Instruments is the identifying part number for the PXI-6542 PXI Digital Waveform Instrument. This module is part of the PXI Express (PXIe) platform, which offers high bandwidth and low latency for data transfer, making it ideal for applications requiring precise timing and synchronization. The 778953-01 Digital Waveform Instrument features 16 data channels enhancing data acquisition and improving efficiency by reducing the need for multiple devices for data processing. When configured for double data rate (DDR) mode, the module can transfer data on the rising and falling edges of the clock signal while with the single data rate (SDR) mode, it can transfer data on the rising edge only. This flexibility makes it suitable for a wide range of digital signal testing, including semiconductor device testing.
The 778953-01 Digital Waveform Instrument supports a variety of triggering and event capabilities, ensuring precise control over test execution. Triggers can be configured for start, pause, script, and other events, and can be routed to different channels or external devices. The module also includes programmable function interface (PFI) channels for additional flexibility in signal routing and control.
In terms of software, the 778953-01 Digital Waveform Instrument is compatible with NI-HSDIO driver software, which provides a comprehensive API for configuring and controlling the module. The recommended software supported by this model is LabVIEW, Lab Windows/CVI, and NET.
The 778953-01 Digital Waveform Instrument is designed to consume power of 15 W, typical, and 20.5 W maximum. It is designed to be operated at an ambient temperature of 0 degrees Celsius to 55 degrees Celsius and storage temperature of -20 degrees Celsius to 70 degrees Celsius with relative humidity ranging from 10% to 90%, noncondensing and storage relative humidity of 5% to 95%, noncondensing. This model complies with IEC 61010-1, EN 61010-1, UL 3111-1, and UL 61010B-1 which makes it suitable and safe to be used in electrical equipment for measurement, control, and laboratory use. This model is not equipped with an ingress protection rating, thus it should not be used in environments where dust, and moisture.
