Flexible Remote Teaching Workplace Configured for DMM Frequency Error Measurement

Our institute is gradually building the modular system of remote access workplaces. It simplifies the design of a new didactic workplace. The principles of the system and the process of adding a new module are explained in the paper. The software part of the recently designed module is oriented towards configurable SCPI communication, where the teacher, as a local user, determines the sequence of commands sent to the device. In the hardware part, we used a digital multimeter (DMM) with this configurability and an arbitrary function generator. This pare of devices allows several measurement configurations. During classes it was employed for additional frequency error measurement of a DMM. We received feedback from 40 students who appreciated the remote tool as a supporting aid.
