Description
High-Voltage PCI Signal Amplification
The Tabor 3322 PCIBus Amplifier is designed for applications that demand high-voltage signal amplification from DC to over 20 MHz. Delivering up to 40Vp-p into high impedance or 20Vp-p into 50Ω, this amplifier overcomes the output limitations of standard PCI signal sources, which are often restricted to low voltages due to power rail limitations. Its fixed gain of x10 can be customized without compromising signal integrity, ensuring precise amplification for critical applications.
Flexible and Safe Configuration
The 3322 provides versatile configuration options including input/output impedance, signal polarity, and grounding. Its floating capability allows operation isolated from case ground up to 250VDC, which is essential in applications where the amplifier must share the same ground level as the source device. Power is drawn solely from the +5V PCI rail, leaving other rails available for additional devices safely and efficiently.
Target Applications
The PCI-based amplifier is ideal for a variety of use cases:
- Automotive testing with signals in the 12–28V range
- Aerospace and aviation signal routing and amplification
- Laboratory PXI/PCI instrumentation requiring high voltage
- Industrial and scientific signal amplification needs
Cost-Effective High Performance
Despite its high-voltage and wideband capabilities, the 3322 remains a compact and cost-efficient PCI amplifier. Its single-slot design allows seamless integration into PCI systems while providing high-fidelity amplification, configurable performance, and low distortion, making it perfect for engineers and researchers seeking reliable signal amplification.
