NI PXIE-4145 4-channel source measurement unit

DESCRIPTION

NI PXIe-4145 4-channel source measurement unit (SMU) is a high-performance, versatile instrument designed for a wide range of applications, particularly those requiring high-pin count measurements. 

Key Specifications

Channels: 4 channels

Voltage Range: ±6 V

Current Range: 500 mA

Operating Mode: Four-quadrant operation

Sensing Capability: Remote (4-wire) sensing for accurate measurements

Core Capabilities

High Sampling Rate:

The PXIe-4145 boasts a high sampling rate, which helps to shorten measurement times and capture transient characteristics of devices under test (DUT).

Fast IV Characterization:

The unit enables rapid IV (current-voltage) characterization of DUTs, facilitating efficient testing and analysis.

Synchronization Capabilities:

With a high-speed sequencing engine, users can synchronize these SMUs with each other or with other instruments (such as switches or high-speed digital test modules).

SourceAdapt Technology:

This technology adjusts the PXIe-4145's response to any load, optimizing performance, enhancing stability, and minimizing transient behavior.

Additional Features

Connectivity and Compatibility:

The PXIe-4145 offers a range of connectivity options, including digital I/O, analog I/O, serial communication interfaces (such as RS-232, RS-485, CAN, etc.), and Ethernet.

It is compatible with various application development environments (ADEs) such as LabVIEW or LabWindows™/CVI™, and supports the Windows operating system.

Precision and Calibration:

The unit is designed for precision measurements, with voltage and current programming and measurement accuracies that can be adjusted and corrected through calibration.

Reliability and Safety:

The PXIe-4145 incorporates reliable safety features, supporting various security protocols (such as SSL/TLS, AES-256 encryption, etc.) and secure boot functionality to ensure data security and integrity.

Recommended Operating Conditions

To ensure optimal performance, it is recommended to minimize cabling lengths to reduce noise pickup.

All connections to the PXIe-4145, including front panel connections and screws, should be secure.

The PXI chassis fan speed should be set to "HIGH," and the fan filter (if present) should be kept clean.

The unit requires a minimum of 30 minutes of preheat time after being loaded and recognized by NI-DCPower to ensure stable operating temperatures.
