NI PXIe-6548

Technical Specifications: Digital Channels: 32 single-ended bidirectional pins Maximum Clock Frequency: 200 MHz Programmable Logic Voltage: 1.2 V to 3.3 V, 100 mV resolution Hardware Bit Error Comparison: Supported Total Power: 32.2 W typical, 33.5 W maximum Connector: VHDCI front connector

Function Features: Per-bank data delay and deskew adjustment. Hardware compare for bit error rate test. Source synchronous clocking. DDS internal clock with sub-Hz resolution. NI-HSDIO driver. Mixed signal system synchronization via PXIe trigger bus.

Application Scenarios: Digital device characterization, semiconductor digital pin test, high-speed protocol test, FPGA interface validation, memory interface test, mixed signal ATE subsystem.

Material Composition: Front panel: aluminum alloy. PCB: high-speed multi-layer PCB. High-speed digital driver/receiver chips. VHDCI high-density connector.

Structural Features: 3U single-slot PXIe form factor. High-speed controlled impedance signal traces. Onboard pattern memory.

Working Principle: Digital pattern data stored in onboard memory. High-speed drivers generate digital waveform at programmed voltage level and timing. Receiver samples incoming digital signal and hardware compares received pattern against expected value for error detection.

Installation Requirements: Install into PXIe chassis slot. Use SHC68-C68-D4 1 m recommended cable. Install NI-HSDIO driver. Calibrate signal deskew after cabling.

Usage Notes: Use specified 1 m cable; longer cables void performance guarantee. Allow 15 minutes warm-up before precision timing measurement. Avoid overvoltage on digital pins. Terminate high-speed signal path as required.
