PXI/CPCI 8-Channel High-Speed Data Acquisition Module for Automated Test
PXI-6212 provides eight synchronous analog input channels in a compact 3U CPCI/PXI module. The module is suitable for transient signal acquisition, impact testing, ultrasonic and acoustic measurement, communications, aerospace, defense, and other time-domain or frequency-domain measurement tasks.
Key Technical Advantages
- Eight Synchronous Inputs: Eight analog input channels support synchronized high-speed acquisition.
- 14-Bit, 125 MSa/s: Each channel supports 14-bit resolution with sampling rates up to 125 MSa/s.
- Configurable Ranges: Input ranges include +/-10 V, +/-5 V, +/-1 V, +/-0.5 V, and +/-0.1 V.
- Multi-Module Sync: Multi-module synchronized acquisition supports larger channel-count systems.
- Large Onboard Storage: Storage options include 256M, 512M, and 1GB sample capacities.
- Flexible Input Path: AC/DC coupling and 1 Mohm / 50 ohm input impedance are supported.
Typical Applications
- PXI-based high-speed parallel data acquisition
- High-frequency, high-dynamic-range signal capture
- Multi-module synchronized acquisition
- Onboard-storage acquisition workflows
Core Specifications

PXI-6212, PXI-6304, or PXI-6207?
| Module | Published acquisition boundary | Choose it when |
|---|
| PXI-6212 | 8 synchronous channels, 14 bits, 125 MSa/s per channel | High-speed parallel capture, large onboard storage, and multi-module synchronisation are the primary requirements. |
| PXI-6304 high-speed ADC | Higher-resolution, channel-isolated acquisition at a lower sampling rate | Resolution and isolated inputs matter more than the PXI-6212 sampling rate. |
| PXI-6143 DAQ module | Wider selectable voltage ranges with buffered lower-speed acquisition | Voltage range, coupling, trigger options, and buffered capture fit the signal map better than the PXI-6212 high-speed boundary. |
| PXI-6207 isolated DAQ | Lower-bandwidth isolated acquisition | Isolated signal capture, rather than the PXI-6212 high-speed boundary, is the defined measurement need. |
