PXIe-6545

The PXIe-6545 is a PXI Digital Waveform Instrument from National Instruments, designed for high-speed digital waveform generation, digital waveform acquisition, mixed-signal test, and automated validation systems. As a 200 MHz, 32-channel PXI digital waveform generator and analyzer, the NI PXIe-6545 can interface with 32 single-ended digital pins and sample digital waveforms at up to 200 MHz. It supports common TTL voltage levels, making it suitable for digital device testing, functional validation, and PXI-based digital communication applications.

The NI PXIe-6545 is useful for engineers who need to generate and acquire digital patterns in a PXI Express test system. It can be used to stimulate digital devices, capture digital responses, verify timing behavior, and test digital communication between components. Because it functions as both a digital waveform generator and analyzer, the PXIe-6545 is suitable for applications that require both digital signal output and digital signal measurement in one module.

One of the main advantages of the PXIe-6545 Digital Waveform Instrument is its 32-channel single-ended digital I/O capability. These digital channels allow users to connect to devices under test, digital buses, test fixtures, embedded systems, and logic-level circuits. With sampling rates up to 200 MHz, the module can support high-speed digital pattern generation and acquisition for timing analysis, protocol validation, and digital functional test.

The National Instruments PXIe-6545 also includes advanced synchronization features for building integrated mixed-signal test systems. This allows engineers to coordinate digital waveform generation and acquisition with other PXI instruments such as oscilloscopes, digitizers, signal generators, RF modules, source measure units, and multifunction DAQ modules. Its synchronization capability is especially useful when digital signals must be tested together with analog, RF, or power measurements.

The PXIe-6545 provides per-bank digital timing features, allowing users to configure timing behavior across groups of digital channels. This is useful for applications that require flexible timing control, digital bus testing, device communication, or synchronized pattern generation. The module can be used in design validation, production test, semiconductor test, embedded device verification, and automated functional test environments.

For system integration, the NI PXIe-6545 is designed for PXI Express platforms and can be installed in compatible PXIe chassis. It works as part of a modular PXI test system where users can combine digital waveform instrumentation with other measurement and control modules. NI lists the PXIe-6545 with part numbers 780993-02 and 780993-03.

The PXIe-6545 PXI Digital Waveform Instrument is suitable for applications such as digital device validation, functional test, digital pattern generation, digital waveform acquisition, protocol interface testing, semiconductor test, mixed-signal validation, and automated production testing. It is especially useful when a test system requires high-speed digital stimulus and response measurement in a compact PXI Express format.

Overall, the NI PXIe-6545 PXI Digital Waveform Instrument is a flexible digital test module for users who need 32-channel single-ended digital waveform generation and acquisition. With 200 MHz sampling, 32 digital channels, TTL voltage-level support, advanced synchronization capabilities, and per-bank digital timing features, the PXIe-6545 is well suited for high-speed digital test, mixed-signal validation, and PXI-based automated test applications.
