1.
Do not clamp the current probe around any conductor, but make sure the
jaws are locked shut.
2. Press the amplifier PROBE DEGAUSS AUTOBALANCE button. Wait for
the degauss/autobalance routine to complete before proceeding. The routine
is complete when the indicator light turns green.
3. Clamp the current probe around the HF current loop.
4.
Enable the output of the leveled sinewave generator.
5. Verify the output level is what is listed for the probe in Table 5--22.
6. Using the peak-peak measurement capability of the oscilloscope, measure
and record the peak-peak reading as
M
1
in Table 5--22 on page 5--41 .
7. Set the oscilloscope time base to 40 or 50 ns/division. Increase the signal
generator frequency to the warranted bandwidth. Refer to the test record for
the warranted bandwidth.
8. Using the peak-peak measurement capability of the oscilloscope, measure
and record the peak-peak reading as
M
2
