Deep insight from new device combining oscilloscope, data acquisition recorder

20 February 2021

Renewable and energy-efficient technologies need robust equipment for effective design and evaluation. Yokogawa Test & Measurement Corporation has recently released a unique device to fit that bill: It combines a multi-channel, mixed-signal oscilloscope with a portable data acquisition recorder to offer deep levels of insight and efficiency.

The new DL950 ScopeCorder captures both high-speed transient events and long-term trends, building on the capabilities of the Yokogawa’s existing DL850E through its ability to handle larger amounts of data at a faster sample rate and with a longer recording time. The DL950 is capable of simultaneous measurement of a wide variety of mechanical parameters.

Design and test engineers must often resort to using multiple test instruments to measure several signals under different conditions. Examples include signals gauging voltage, current, temperature, vibration, acceleration, strain and other electro-mechanical and physical phenomena — and the number of measuring points is on an upward trend.

The possibility of viewing all signals with one common instrument simplifies data synchronization and the management of multiple data formats and storage locations. Engineers using the DL950 can mix and match input types with over 20 types of isolated input modules. Eight modular slots provide up to 128 channels of measurement data, allowing data synchronization. Moreover, up to five DL950 units can be connected for the analysis of correlations among data. Accurate synchronized measurement in conjunction with other instruments is also possible via the IEEE1588 high-precision time synchronization protocol for networked devices.

As the company points out, the mechatronics industry has a growing need for the measurement not only of electrical signals but also of noise, vibration and harshness (NVH). Industrial equipment manufacturers may find the DL950 is an ideal fit for testing high-efficiency motors, robots and sensors.
