New oscilloscope probes offer expanded capabilities for high frequency, high voltage applications and low current analysis

Yokogawa has launched a new range of high frequency, high voltage differential oscilloscope probes, combining proven features of its existing probes with new capabilities.
The new range replaces six probes with three, offering a simpler choice for development engineers looking to test high performance systems.
Recent trends for higher voltages in electric vehicles, railway inverters, new energy sources such as renewable solar and high-voltage commercial power lines such as 400 Vrms have shown the need for oscilloscope probes that can handle these high voltages.
Building on the proven 701927, the 701977 is designed for the evaluation of inverters, including 3.3 kV railway drive inverters, as well as the measurement of high voltage surge noise waveforms.
The 701977 offers a maximum input voltage of 7,000V peak at 50 MHz, with an attenuation ratio of 100:1/1000:1. High voltage black and red alligator clips are supplied as standard. 
Another development of the 701927, the 701978 meets the needs of renewable energy, high voltage photovoltaic systems. The 701978 offers a maximum differential voltage of 1,500V at 150MHz, with an attenuation ratio of 50:1/500:1. The new probe offers the same accessories as the existing 701927 – Pinchertip (Red, Black), a 1 m extension lead, a 100 Ω resistance adapter and a 150 Ω resistance adapter.
Both these probes are powered from the power terminal of DLM oscilloscopes’ or from separate external power supply and use BNC type connecters.
The 701925 is a new high frequency differential probe. It offers a 500 MHz bandwidth and a wide input voltage range of +/- 35V, with an attenuation ratio of 50:1. This makes the probe ideal for measuring high-speed floating and differential signals such as CAN FD, making it possible to measure large surges accurately, something which existing differential probes can struggle to achieve.
Accessories are as supplied with the 701924 and include 10-cm pair leads, 5-cm pair leads, red and black micro clip and 6-cm ground extension lead. The 701925 is powered through the Yokogawa probe interface of DLM oscilloscopes.
Also launched are two new current probes, offering a wide range combined with high-sensitivity current measurement.
The 702915 and 702916 are three-range current probes designed for low current measurement in the development of consumer products, IoT devices and automotive systems. The new probes offer 10 times the sensitivity of conventional current probes as well as having a higher Signal to Noise Ratio (SNR) than existing products.
The bandwidth of the 702915 is DC to 50 MHz (-3 dB), with that of the 702916 being DC to 120 MHz (-3 dB). With three ranges - 0.5A, 5A and 30A - the probes enable a single instrument, an oscilloscope or a Yokogawa ScopeCorder, to analyze all current levels from standby to inrush. 
This makes the probes ideal for many current measurement applications, from measurement of standby-current of home appliances, automotive parts such as ECUs and industrial equipment, measurement of current consumption and standby current for low power IoT devices and control signal currents and inrush currents in motors and industrial equipment.
For example, combining the high sensitivity of the Yokogawa DLM5000 and the new probes allows manufacturers to measure very low currents of less than a milliamp, providing analysis of the extremely low standby currents found in vehicle keyless entry systems.
“These new probes take our already excellent products to new levels,” says Terry Marrinan, Yokogawa’s Vice President, Test & Measurement, for Europe & Africa. “Manufacturers needing accurate testing of high voltage, high frequency signals or precision monitoring of very low currents now have the features they need in convenient, easy to use probes. With these tools, manufacturers can easily test a wide range of products to meet the needs of new industries and consumers.”

About Yokogawa Test & Measurement


Yokogawa has been developing measurement solutions for 100 years, consistently finding new ways to give R&D teams the tools they need to gain the best insights from their measurement strategies. The company has pioneered accurate power measurement throughout its history, and is the market leader in digital power analysers.

Yokogawa instruments are renowned for maintaining high levels of precision and for continuing to deliver value for far longer than the typical shelf-life of such equipment. Yokogawa believes that precise and effective measurement lies at the heart of successful innovation - and has focused its own R&D on providing the tools that researchers and engineers need to address challenges great and small.

Yokogawa takes pride in its reputation for quality, both in the products it delivers - often adding new features in response to specific client requests - and the level of service and advice provided to clients, helping to devise measurement strategies for even the most challenging environments.

The guaranteed accuracy and precision of Yokogawa's instruments results from the fact that Yokogawa has its own European standards laboratory at its European headquarters in The Netherlands. This facility is the only industrial (i.e. non-government or national) organisation in the world to offer accredited power calibration, at frequencies up to 100 kHz. ISO 17025 accreditation demonstrates the international competence of the laboratory.
