Virtual Test Equipment Interface (9407)
The LVDAM-COM system consists of the Virtual Test Equipment Interface module and the Lab-Volt software Data Acquisition and Management for Telecommunications (LVDAM-COM). The LVDAM-COM system can replace the Lab-Volt conventional instruments (Frequency Counter, Model 9403, True-RMS Voltmeter/Power Meter, Model 9404, and Spectrum Analyzer, Model 9405) in the Analog Communications Training System, Model 8080, and Digital Communications Training System, Model 8085-1.
The Virtual Test Equipment Interface (VTEI) module links the personal computer running the LVDAM-COM software with the Lab-Volt analog and digital training systems. Data exchange between the VTEI module and the personal computer is made through a standard parallel port. The VTEI module is designed to meet the high frequency signal requirements for telecommunications systems. It provides the necessary hardware to implement a dual trace oscilloscope, a spectrum analyzer, a true-RMS voltmeter, and a frequency counter. All inputs are fitted with BNC connectors and are fully protected against short circuits and misconnections.
The LVDAM-COM software consists of a complete set of instruments that runs on an IBM®-compatible personal computer under the Microsoft™ Windows operating environment. Each instrument appears as a window on the computer screen. Available instruments are: a dual channel oscilloscope, a spectrum analyzer, a true-RMS voltmeter, and a frequency counter.
