Picoprobe Power Supply

The GGB Industries / Picoprobe 7/7A Probes were designed as companion probes to the Picoprobe 12C and 18C for driving integrated circuit lines so the 12C or 18C can be used to measure the response of adjacent nodes. The Picoprobe 7 consists of a flexible six 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 three millimeters of the fine tungsten probe point, thus minimizing capacitive coupling to other parts of the circuit. The replaceable coaxial probe tips are manufactured in various point sizes and can also be bent to any shape in order to accommodate a variety of probing geometries.

The Picoprobe 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 of six feet in length is standard on the 7A; however, when used for capacitance measurements it is recommended to use a shorter three foot cable.
