Cal Test Electronics debuts active FET probe kit

Aug. 28, 2017

Yorba Linda, CA. Today Cal Test Electronics introduced a new active FET probe kit. The CT4121 is a compact FET probe with high input resistance and low input capacitance. With a 1.2-GHz bandwidth (-3 dB), this probe is suitable for timing analysis or troubleshooting of high-speed logic circuits, for design verification of disk drives, and for wireless and data communication design. The CT4121 can measure up to ±40 V (DC + AC peak).

Compatible with oscilloscopes from major manufacturers, the probe is powered by the included 9-V battery or direct from the oscilloscope using the included USB power lead. Attenuation is 10x, and accuracy is ±2%. Input resistance and capacitance are 1 MΩ and 3 pF typical. Rise time (probe only) is 291 ps. Output voltage swing is ±1.5 V (driving a 50-Ω oscilloscope input). The probe comes with a power indicator LED and an SMD accessory kit. MSRP is $760, and the CT4121 is available immediately.
