The CT4121 from Cal Test is a small FET probe featuring high input resistance and low input capacitance. The 1.2 GHz bandwidth makes the probe perfect for timing analysis or troubleshooting high speed logic circuits, for design verification of disk drives, and for wireless and data communication design. The CT4121 is equipped for measurements up to ±40 V (DC + AC peak). It’s suited for use with oscilloscopes from all major manufacturers and is powered by the included 9 V battery or direct from the oscilloscope using the included USB power lead.
