The Tektronix P6021 is a 125-turn AC current probe for oscilloscopes. It can be used with the included passive termination, a type 134 current probe amplifier, or a 3A9 or 7A14 current probe amplifier scope plug-in.
Bandwidth is up to 52 MHz.
The sister model P6022 has higher bandwidth but also a higher LF cut-off frequency and lower peak current rating.
