National Instruments recently introduced a new PXIe digital waveform instrument, the PXIE-6544. With its excellent performance and flexibility, this device meets the needs of high-speed digital signal testing and measurement, and is widely used in many fields such as industrial automation, communications, semiconductor testing, and scientific research and education.

The PXIe-6544 is a 100 MHz 32-channel digital waveform generator and analyzer capable of sampling digital waveforms at rates up to 100 MHz and connecting to commonly used transistor-transistor logic (TTL) voltage levels. It has advanced synchronization capabilities for building integrated mixed-signal test systems and provides digital timing capabilities for each storage unit. In addition, the PXIe-6544 supports digital waveform sampling and generation up to 200 MHz, with the ability to connect to a variety of standard TTL and low-voltage differential signals (LVDS) and configurable voltage levels.

Another notable feature of the PXIe-6544 is its high capacity of on-board memory and trigger and Pattern ordering capabilities. Some models also support double data rate (DDR) technology and real-time hardware data comparison, which further improves their performance in real-world applications. With streaming rates of up to 660 MB/s to host PC memory and 400 MB/s from host PC memory, the device is ideal for applications that require high streaming rates, such as streaming of high-quality computer video signals. Used to generate or capture LCD screens, TV components, high-quality signals (up to 1080p, 60 Hz), RF baseband devices, and HD radios.

In addition, the PXIe-6544 offers improved timing and synchronization capabilities, and the on-board available DDS clock offers up to 100 MHz subhertz resolution, helping users clock (generate or collect) information with greater precision without the use of an external clock. These features enable the PXIe-6544 to provide high performance and flexibility in a wide range of applications, providing reliable technical support for industrial automation and test and measurement systems.

The introduction of the PXIe-6544 not only expands National Instruments’ product line in the field of PXI digital waveform instruments, but also provides engineers and researchers with a powerful tool to address a variety of complex test and measurement challenges. With the continuous progress of technology and the increasing demand for applications, PXIe-6544 is expected to play a more important role in the field of test and measurement in the future.
