High Performance Microwave Probes

Model 1100B

The Model 1100B Picoprobe sets new standards in microwave probing performance. Benefiting from coaxial techniques, which have inherent low loss and low dispersion characteristics. With its individually spring loaded, Beryllium-Copper tips, the Model 1100B Picoprobe provides reliable low resistance contacts.This reliable low resistance contact is one of the keys to providing highly repeatable measurements. The Model 1100B Picoprobe also allows direct viewing of the probe tips for accurate positioning. The Model 1100B Picoprobe bias T provides a direct low resistance DC pathfor supplying up to 100 mA to a device under test. The bias T also has special circuits which add loss at frequencies below the waveguide cut off frequency.
