The NI PXIe-6544 digital waveform generator/analyzer features 32 software selectable bidirectional channels clocked at a maximum of 100 MHz. The selectable voltage levels of 1.2, 1.5, 1.8, 2.5, and 3.3 V work with the most common logic levels and are ideal for conducting tests on semiconductor devices, such as analog-to-digital converters (ADCs), digital-to-analog converters (DACs), ASICs, and microcontrollers. For example, with a 16-bit, parallel interface, 100 MS/s dual-channel DAC, you can use the NI PXIe-6544 to generate data on 32 lines (continuously or in bursts) to test the DAC at its maximum clock rate. You can also pair this module with other NI modular instruments, including digitizers or source measure units (SMUs), to characterize the DAC for various tests at higher rates.
Streaming rates of 400 MB/s to and from host PC memory make the NI PXIe-6544 ideal for applications requiring high streaming rates. You can use this module to stream high-definition digital video signals for generation or acquisition and to test LCD screens, television components, high-definition signals (up to 1080 p at 60 Hz), RF baseband devices, and HD radio.
In addition, the NI PXIe-6544 features enhanced timing and synchronization capabilities. The onboard DDS clock provides subhertz resolution up to 100 MHz, helping you clock data (generation or acquisition) with higher precision without using an external clock. Also, you can now test applications requiring arbitrary clock frequencies and export the onboard clock to other instruments through the backplane of a PXI Express chassis or through an SMB connector on the front panel of the device. Additionally, you can clock your data by importing an external clock through the front panel or backplane. With these features, you can synchronize the NI PXIe-6544 with other analog or digital instruments.
