NI GPIB-140A Product Introduction

NI GPIB-140A is a high-performance GPIB(General Purpose Interface Bus)bus extender or controller module produced by National Instruments.It can connect GPIB devices that are far away from the main GPIB controller and provide additional GPIB ports to connect more GPIB devices.

Main Functions and Features

Extended GPIB Coverage

Through signal conditioning circuits,NI GPIB-140A can maintain the integrity of GPIB signals over longer cable lengths.

Compensate for signal attenuation and distortion that may occur when using longer cables to ensure reliable communication between devices.

Multi-device connection

Provides additional GPIB ports to connect more GPIB devices.

It is very beneficial for complex test setups that require multiple instruments to be connected to a single GPIB bus.

Isolation and Protection

Provides isolation between different segments of the GPIB network,protecting connected devices from electrical interference and potential damage caused by ground loops or surges.

The level of electrical isolation provided is critical for lab environments with mixed high-voltage and low-voltage test equipment.

Compatibility and Integration

Fully compatible with GPIB standards,compliant with IEEE 488.1 and IEEE 488.2 standards.

Can be seamlessly integrated with GPIB-compatible devices produced by different manufacturers,such as Agilent,Tektronix,and Keithley.

High Precision and Stability

NI GPIB-140A is designed for test and measurement applications with high precision and stability.

Adopts sophisticated clock and timing circuits to ensure the accuracy and consistency of output signals.

Programming and Control

Supports a variety of programming interfaces and control software,including LabVIEW,Python,C++,etc.

Users can write custom programs according to their needs and perform flexible control and configuration.

Fiber Extension Function

NI GPIB-140A also has fiber extension function,which can further extend the transmission distance of GPIB signals.

Application Fields

NI GPIB-140A is widely used in various test and measurement fields,including but not limited to

Electronic manufacturing test equipment:connect additional oscilloscopes,signal generators,logic analyzers,etc.

Semiconductor test laboratories:connect multiple test probes and measuring instruments to a GPIB bus.

ATE(Automated Test System):Improve the flexibility and scalability of GPIB-based test infrastructure.

Industrial process control:connect GPIB-enabled sensors and monitoring equipment to central control systems(although GPIB is not as common as other fieldbuses in industrial process control,it is still useful in some cases where high-precision measurement and control of specific equipment is required).
