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 ...

The CT4121A, a new active FET probe kit, is compact with high input resistance and low input capacitance. With a 1.2-GHz bandwidth (-3 dB), this probe is suitable for timing analysis or ...

It’s a problem that has dogged electronic engineers since the first electrons were coaxed along a wire: that measuring instruments can themselves disrupt the operation of a circuit. Older multimeters ...
