Product Short Description
Product Name
PXIe-6548 200 MHz 32-Channel Digital Waveform Generator/Analyzer
Product Overview
The PXIe-6548 is a high-speed digital I/O module that generates and acquires digital patterns. It is used for logic verification, parallel-bus testing, and high-speed digital characterization.
Description
Technical Specifications
- Channels: 32 bidirectional single-ended digital lines
- Maximum Data Rate: 200 MHz single data rate
- DDR Pattern Rate: Up to 400 Mbit/s
- Programmable Logic Voltage: 1.2 V to 3.3 V
- Onboard Memory: 64 MB pattern storage
- Output Impedance: 50 Ω programmable per pin
- Multi-module Sync: D-Star trigger bus
- Bus: PXI Express hybrid-compatible slot

Functional Features
- Pattern generation and acquisition
- Real-time bit-error comparison
- Per-group timing delay adjustment
- Programmable I/O voltage levels
- External sample clock input
- D-Star differential trigger synchronization
Working Principle
The module stores digital vectors in onboard memory and drives them with a precise sample clock. During acquisition, received logic levels are compared against expected data for bit-error detection. D-Star and PFI lines coordinate multi-module timing.
Application Scenarios
- FPGA functional verification
- MCU and digital IC test
- Parallel bus debugging
- High-speed digital communication test
- ATE digital subsystem
- Logic interface validation
Installation Requirements
- Install in PXI Express hybrid slot
- Use high-quality digital I/O cables
- Set I/O voltage before connecting device under test
- Connect external clock when required
- Configure D-Star routing for multi-board systems
Usage Notes
- Do not drive pins beyond configured logic voltage
- Terminate transmission lines appropriately
- Avoid excessive cable length at 200 MHz
- Validate timing parameters before production test
- Use bit-error masking only with documented test intent
