Passive oscilloscope probes
19 November 2014
Test & Measurement
The Model 702902 and 702906 from Yokogawa are 10:1 passive oscilloscope probes that operate over a wide temperature range from -40°C to +85°C. As a result, they are ideally suited to use in accelerated testing and validation methods where temperature cycling is part of the test procedure.
The 702902 is designed for use with the isolated BNC input modules of Yokogawa’s DL850E ScopeCorder family, whereas the 702906 is intended to be used with the non-isolated BNC inputs of the Yokogawa DLM4000 and DLM2000 series of oscilloscopes.
The probes are fitted with long (2,5 m) cables, making it easy to keep the measuring instrument away from the high-temperature measurement point. Longer probes are also required when connecting the measuring instrument to a temperature-controlled chamber. To ensure reliability under severe environmental conditions, these probes have been proved to withstand a cable mount pulling force of 60 N, and have been tested over 500 temperature cycles.
In addition to supporting isolated and non-isolated inputs, these probes can also be used with a range of probe tip conversion adaptors to connect the probe to the application in the most convenient way. The choice of adaptors includes safety mini clips, fork terminal adaptors, small or large alligator clips, and 4 mm conversion adaptors with pincher tip or safety banana connectors.
Typical applications include accelerated testing and validation of automotive parts and designs inside a temperature chamber; and the environmental testing of power converters designed for outside installations, such as the inverters and transformers used for solar photovoltaic and wind-turbine power generation.
Other uses include the evaluation and environmental testing of sensors and actuators used in automotive, railway, aerospace and marine applications, and the testing of home appliances such as air conditioners, cookers and refrigerators.
