1 Introduction
Overview
The CT4121 is a compact FET probe with very high input resistance
and low input capacitance. With a 1.2 GHz bandwidth, this probe is
ideal for timing analysis or troubleshooting high speed logic circuits,
for design verification of disk drives, as well as for wireless and data
communication design. The CT4121 can measure up to ±40 V (DC +
AC peak). Compatible with oscilloscopes from all major manufacturers,
the probe is powered by the included 9 V battery or direct from the
oscilloscope using the included USB power lead.
