Tektronix has launched a new series of oscilloscope probes specifically designed for measuring very high frequencies, which also give developers more options for connecting probes to compact, high-density circuits.
 
Effective testing and debugging of very high-speed signals requires probes that minimize signal losses. Most low-loss probes have a separate instrumentation amplifier that is connected to the probe tip through a cable. The new P7700 series of probes from Tektronix takes a completely different approach, with the input amplifier integrated into the probe tip less than 4 mm from the connection point. This minimizes signal loss as well as probe capacitance and reduces noise susceptibility.
 
Another advantage of the P7700 probes is that they can be connected to very small components on the circuit board through solder tips. A set of tips is included with each probe, and their relatively low cost makes them easily replaceable. With prices starting at $8,500, the P7700 probes are clearly intended for professional users.
