Stationman Speaker Probe
250 SSP
-
This probe is designed for those technicians that want the best tool available. The Model 250SSP is supplied with a cone-shaped tip and a duckbill tip that is longer and flatter, permitting insertion into larger cables, or cables under tension where slack cannot be obtained. Another feature is the built in speaker for audio without the need for a butt set or headset. The speaker is operated by a slide switch that has a "lock" position for continuous monitoring.

Impedance Measurement
CITS880s
-
Finer geometries and thinner copper can present a challenge for fabricators measuring impedance on leading edge PCBs. The CITS880s answers that challenge with the introduction of Launch Point Extrapolation (LPE). LPE extrapolates the TDR response back to a point close to the start of the transmission line effectively allowing to users more accurately to measure the instantaneous or incident impedance of the line.

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
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.
