Ideal for device characterization and modeling, Infinity probe combines extremely low contact resistance on aluminum pads with unsurpassed RF measurement accuracy for highly reliable, repeatable measurements. Proprietary thin-film and coaxial probe technology reduces unwanted couplings to nearby devices and transmission modes.
It is useful to stop and consider what you really wish to measure. When high-frequency probes are used with a network analyzer (after calibration), what is measured will be what the probe tips contact. This includes the pad parasitics, and parasitics associated with the interconnects from the pad to the other devices on your substrate. If you want to measure a device independent of the pad effects, then it is useful to make the pads small, so their effects will be negligible or easily subtracted (de-embedded) from the measured data. In any event, it is important to be clear that when using a network analyzer you will be measuring everything past the end of
the probe tips, unless you use special calibration/correction techniques. In most applications this is exactly what you want; a measurement of the circuit’s electrical performance.
