GGB model 7 ａnd model 7A           

6英尺长线缆，50欧姆阻抗，直流到500MHz

PICOPROBE? MODEL 7 was 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. 

PICOPROBE? MODEL 7A, an unterminated version, can be used for capacitance ａnd resistance measurements or in low to medium speed ** 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.
