Designing and Development of Automated Thermal Test Laboratory Solution for Wireless Customer-Premises Equipment (CPE)

Company: VSK Test Solutions
Author(s): Puneet Kapoor
NI Product(s) Used: LabWindows/CVI, Multifunction DAQ Card
Industry: Wireless Communication


The Challenge

Complex Wireless Customer-Premises Equipment (CPE) testing can be challenging due to wide range of functionality and required testing.  We needed a system that has the ability to automate software & hardware components to test CPE more efficiently and cost-effectively.

 

The Solution 

“Used National Instruments LabWindows/CVI Software to develop efficient and robust command-line interface to control & monitor each of the test instruments and interface with existing test management software. 

 

Introduction

Thermal Test Software Automation

Test Hardware for thermal automation was a Programmable AC Power Supply, AC/DC Electronic Load, AC Power Meter, Data Acquisition Unit and back-haul network for simulated environment. Test Software was command-line interfaces for each test instruments deployed on the test industrial computer and each command line was developed in Lab windows CVI programming environment. Client was already using a tool called Test Shell for their test management process and so all command line interfaces needs to be compatible with Test Shell. Command-line was having all the functions/command available in the instrumentation. 

 

Thermal Chamber Lamp Automation

Designing and development of a custom hardware electronic solution to automate thermal chamber lamp through software. Thermal chamber lamp is a 500W Halogen light powered by 230V AC and it needed to be switch on/off depending on the temperature of the chamber.

VSK Test Solutions have designed and developed the lamp automation box which is controlled by National Instruments Multifunction Digital Input/Output card.
