    (cont) Introduction Performance Characteristic The Tektroni x P6021 5 foot and 9 foot Current Probes are designed to measure alternatin g current waveform s. These probes, used with current devices such as the Type Risetime (with 580 134 Current Probe Ampl ifier, 7 A 14 Current Probe Ampl i­...
  • Page 6: Installation

    200 mA and termination contain adjustments to optimize perform­ ance, matching the input characteristics of the vertical am­ plifier. To use the probe, first connect the P6021 Termination to the vertical input of the oscilloscope. Then connect the P602 1 Current Probe to the termination (see Fig. 2-1 ).
