With its individually spring loaded, Beryllium-Copper tips, the Model 120 Picoprobe provides reliable contacts, even when probing non-planar structures. This reliable low resistance contact is one of the keys to providing highly repeatable measurements (-50 db) at W band frequencies.
The Model 120 Picoprobe also provides direct viewing of the probe tips for accurate positioning.
The Model 120 Picoprobe sets new standards in microwave probing performance.
Benefiting from coaxial techniques, which have inherent low loss and low dispersion characteristics, the Model 120 Picoprobe achieves an insertion loss of less than 1.75 db and a return loss of greater than 15 db over its frequency range. ( see accompanying data)

The smooth inwardly spiraling line shows the increasing loss of the 50 ps coplanar line with frequency, coupled with a smoothly changing phase.
