Engineers are using an ever-increasing variety of devices and test points in their designs. In order to access these test points conveniently, today’s probing solutions need to be versatile, small and lightweight, while still maintaining a high bandwidth. LeCroy’s new HFP series of probes is designed to meet these challenges.

Convenient Hands-Free Probing

Five different styles of tips make probing easier than ever. In addition to a traditional Straight Tip, a Sharp Tip allows easier access to tightly-packed test points and circuit vias. The Bent Sharp Tip-made out of titanium-is ideal for making contact on devices that are spaced close together and prevent the probe from being oriented perpendicular to the circuit. The IC Lead Tip has insulation on one side so it can be wedged between small-geometry IC leads without shorting the test points. The Discrete SMD Tip is designed to fit tightly on surface mount capacitors, resistors and other components.

In conjunction with these innovative probe tips is the LeCroy FreeHand probe holder, which holds the probe on test points. This means several probes can be used at the same time on a variety of test points while maintaining short signal paths to preserve signal fidelity. The end result of “HFP hands-free probing” is the enhanced ability to analyze waveforms instead of focusing on keeping the probe in place.

In addition to these new attachment techniques, traditional IC clips, wire leads, and square pin adapters are available.

Easy to Use

When the probe is connected to an oscilloscope channel, our new patent-pending AutoColor ID feature automatically illuminates the probe head in that channel’s trace color. Users no longer need to manually apply plastic rings or colored tape to determine which channel the probe is connected to.

With the ProBus® interface, the HFP probes become an integral part of the oscilloscope. The probe offset is controlled from the oscilloscope’s front panel.

Use with Other Test Instruments

When used in combination with the ADPPS adapter for ProBus and power supply, the HFP1000 can be used on any manufacturer’s oscilloscope or other test instrument. However, the AutoColor ID feature will not function with non-LeCroy oscilloscopes.
