ions
CAUTION. To avoid damaging the probe, do not disconnect the probe termination
when measuring high currents. Leaving the probe cable unterminated can cause a
high voltage to develop in the secondary winding which may damage the current
probe transformer.
1. Connect the current probe calibration fixture to the fast rise output of the
calibration generator.
2. Set the fast rise output to maximum (1 V
pp
)
3. Connect the P6022 cable BNC connector to the termination.
4. Connect the P6022 termination to the oscilloscope Ch 1 input.
5. Set the P
6022 termination sensitivity to 1 mA/mV.
6. Connect the probe to the current probe calibration fixture. The figure below
shows t
he proper probe orientation to the current probe calibration fixture.

7. Adjust C28 and C29 (in the termination), and then R10 (through the hole
in the probe body) to minimize aberrations and achieve the best flat-top
response. The adjustment locations are shown in the illustration. (See
Figure 8 on page 24.)
