PP007-WR PP007-WS Passive Probes Key Features • Compact probe head • Supports fine pitch SMD probing • Rugged, sharp tip • HF optimized connection accessories • Over 30 accessories • Low input capacitance The PP007 embodies leading technology in passive probe design. The small probe is optimized for maximum waveform fidelity, including high frequency signal components, in a rugged probe suitable for every day. The sharp probe tip (rigid tip is included) is spring loaded, allowing it to retract into the narrow probe head. The tip does not slip off the object being probed — important when probing small geometry surface-mounted components. Probing dense circuits is easier with the small 2.5 mm ground sleeve, which provides much better visibility than 5 mm and 3.5 mm probes. Optimized for HF Applications The input capacitance of the probe is very low for a passive probe — to minimize loading of high frequency signals. However, keeping any resonance beyond the passband also requires low inductance in the interconnections. Probes with limited interconnection accessories often force the user to extend the input or ground lead lengths to connect to the circuit — a practice that adds inductance and lowers the resonate frequency. Accessories such as the ground spring and innovative ground blade (PK007-013) provide a very low inductance ground interconnect. Copper foil tape, (PK007-014) included with the probe, can be placed on top of an IC and connected to its ground pins to create a convenient ground plane for the probe to connect to. Used with the ground blade, this method provides an ideal ground connection for probing signals with high frequency content. For applications which require the flexibility of a longer ground lead without compromising high frequency performance, the optional HF-compensated ground lead (PK007-030) provides a solution. A passive network in the lead itself reduces the loading effect of any resonance.

Ground Blade Used with Copper Foil Ease in Probing SMT Circuits In addition to the small probe head size, the PP007 is augmented with several accessories to simplify probing dense surface mounted circuit assemblies. Insulating probe caps with guide fingers (PK007-009, 010, 011,012) keep the small probe tip centered on the IC lead and prevent it from shorting to adjacent leads. The IC Caps are supplied in a range of sizes designed for IC lead pitches from 0.5 mm through 1.27 mm. Optional accessory kits contain 0.5 mm micro clips for attaching to the smallest IC leads, along with adapter...
