Picoprobe
Since 1980, GGB Industries, the originator of the Picoprobe® line of microwave and oscilloscope probes, has served the on-wafer probing needs of the worldwide semiconductor industry, beginning with a line of high impedance troubleshooting probes for diagnostic studies of the internal workings of complex logic and memory chips. In 1988, GGB Industries, Inc., revolutionized on-wafer microwave probing with a new patented coaxial microwave probe having 50 ohm coplanar flexible tips. The introduction of a high-performance W-band millimeter wave probe in 1992 established GGB Industries, Inc., as the world leader in microwave probes.

Integrated Balun Probes
This is an example of a 900 MHz Integrated Balun Probe. It incorporates a 50 ohm unbalanced to 200 ohm balanced differential transformer. The probe can be built with or without a center tapped ground needle and may also incorporate DC bias through the differential pair or via separate needle contacts.

Dual Microwave Probe
The PICOPROBE® DUAL MICROWAVE PROBE consists of two separate probes mounted on a single holder. One probe is fixed to the holder; the other is adjustable. Each probe may be individually configured with GSG, GS, or SG footprints having any fixed pitch from 50 to 2540 microns. The probe to probe (signal to signal) spacing is user adjustable over a 4000 micron (160 mil) range. When ordering, an initial signal to signal spacing should be specified (up to .75 inches).

High Impedance Active Probes
12C
A high speed, high input impedance active probe for measuring the internal node voltage of integrated circuits. The input is 1 megohm shunted by 0.1 pf and the rise/fall times are 0.8 ns. This instrument has full dc capability and can be used with any oscilloscope. The Model 12C was specially designed so that when used in conjunction with a high input impedance oscilloscope, signal attenuation is 10:1 and with a 50 Ohm input, signal attenuation is 20:1.

10
PICOPROBE® MODEL 10 is a multipurpose, high speed, passive probe which can be used for driving as well as receiving signals. The Model 10 consists of a one meter length of flexible 50 ohm coaxial cable terminated by a carefully trimmed SMA on one end and by a miniature, high speed 50 ohm connector, specially developed to receive Model 10 replaceable coaxial probe tips, on the other. The 50 ohm coaxial cable was custom designed for Model 10 to be high speed, yet very flexible, so that moving the cable would not disturb the probe points.

High Impedance Active Probes
7
Designed as a companion probe to Models 12C and 18C for driving integrated circuit lines so the Model 12C and 18C can be used to measure the response of adjacent nodes. The Model 7 consists of a flexible 6 foot, 50 ohm coaxial cable accurately terminated to 50 ohms in order to avoid undesirable reflections. A special miniature connector receives replacement coaxial probe tips that provide a shielded environment to within 3 mm of the fine tungsten probe point, thus minimizing capacitive coupling to other parts of the circuit. The replaceable coaxial probe tips are offered in various point sizes and can also be bent to any shape in order to accommodate a variety of probing geometries.

High Impedance Active Probes
7A
An unterminated version, can be used for capacitance and resistance measurements or in low to medium speed signal applications where a 50 ohm termination is not required. A flexible coaxial cable length of 6 feet in length is standard on the Model 7A; however, when used for capacitance measurements, GGB Industries, Inc., recommends using a shorter 3 foot cable. If a shorter length of cable is desired for capacitance measurements, please specify it when ordering (Model 7A-3ft.). Please note that Model 7A uses Model 7 replacement tips.

High Impedance Active Probes
18C & 19C
High impedance probes, PICOPROBE® MODEL 18C and MODEL 19C, combine the most advanced MOS and bipolar technologies with special, low capacitance packaging techniques to achieve truly remarkable electronic measurement capabilities. While being manufactured each instrument is individually optimized for the best possible performance. The extremely low input capacitance, high input impedance, and almost negligible input leakage current permits the direct probing of even the most sensitive MOS dynamic nodes. At the same time, the full dc capability of this Picoprobe coupled with the high speed capability permits the full characterization of circuits.
