Yokogawa introduces passive probes for dense PCBs
Two passive oscilloscope probes, the Model 701949 and 702907, from Yokogawa expand the usability and applications of Yokogawa’s DLM3000 mixed signal oscilloscope.
The 701949 10:1 miniature passive probe is designed for high density PCBs. It has a slim probe head that provides good visibility during operation. It also features a built-in spring mechanism at the tip that prevents slippage by automatically adjusting the load.
There is a range of accessories available, for high-speed signals such as ICs and high-density mounting boards. The 701949 frequency bandwidth ranges are DC to 500MHz, with an input voltage of ±400V RMS.
The 702907 has a wide operating temperature range of -40 to +85 degrees C and a long probe length of 2.5m to keep the measuring instrument away from the high temperature measurement point. Longer probes are also required to connect the measuring instrument to a temperature-controlled chamber.
Frequency bandwidth ranges are DC to 200MHz, with an input voltage of ±1000V DC and AC peak.
The probes can operate reliable under severe environmental conditions, says Yokogawa. The probes have been tested to withstand a cable mount pulling force of 60N and have been tested over 500 temperature cycles.
The probes can also be used with a range of probe tip conversion adapters to connect the probe, for example, using safety mini clips, fork terminal adapters, small or large alligator clips, and 4mm conversion adapters with pincher tip or safety banana connectors.
Typical applications include accelerated testing and validation of automotive parts, testing 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. They can also be used for the evaluation and environmental testing of sensors and actuators used in automotive, railway, aerospace and marine applications, and to test home appliances such as air-conditioners, cookers and refrigerators.
