Model 500B Picoprobe with bias T
Model 500B High Performance
Microwave Probes
The Model 500B Picoprobe sets new
standards in microwave probing performance.
Benefiting from coaxial techniques,
which have inherent low loss and low dispersion
characteristics, the Model 500B
Picoprobe achieves an insertion loss of
less than 4.0 db and a return loss of greater
than 15 db over its frequency range (see
accompanying data).
With its individually spring loaded,
Beryllium-Copper tips, the Model 500B
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
The Model 500B Picoprobe
also allows direct viewing of the probe tips
for accurate positioning.
Any pitch (tip spacing) is available, however
25 to 55 microns is recommended.
The probe can be configured with Ground-
Signal-Ground (G,S,G), Ground-Signal
(G,S), or Signal-Ground (S,G) tip footprints.
We recommend a G,S,G footprint
for best performance.
