To achieve the highest accuracy when taking the following measurements, turn
on averaging and use the peak-to-peak measurement function, rather than manual
cursor measurements.
1. Connect the current probe calibration fixture to the sine wave generator
output using the appropriate adapters.
2. Connect the probe to the current probe calibration fixture.
3. Ensure that the termination sensitivity is set to 2 mA/mV.
4. Set the oscilloscope vertical deflection to 10 mV/div.
5. Set the oscilloscope horizontal scale to 10
m
s/div.
6. Set the sine wave calibrator frequency to 50 kHz and 5V
p-p
output.
7. Adjust the sine wave amplitude for a 50 mV
p-p
signal (5 divisions). Use the
peak-to-peak measurement function and averaging (16 or greater) for
measurements. You can increase the vertical resolution by fine-adjusting the
volts/div to obtain nearly 8 divisions of deflection.
8. Increase the sine wave generator frequency until the signal amplitude is
35.4 mV. Adjust the oscilloscope time/division as necessary.
9. Check that the frequency of the sine wave generator is ≥60 MHz on the
oscilloscope display.
10. Reset the sine wave generator frequency to 50 kHz.
11. Reset the oscilloscope horizontal scale to 10
m
s/div.
12. Decrease the amplitude of the sine wave generator output until the oscillo-
scope display is one division tall.
13. Set the oscilloscope vertical deflection to 2 mV/div.
14. Set the termination sensitivity to 10 mA/mV.
15. Adjust the sine wave amplitude for a 10 mV
p-p
signal (5 divisions). Use the
peak-to-peak measurement function and averaging (16 or greater) for
measurements.
16. Increase the sine wave generator frequency until the signal amplitude is
7.07 mV. Adjust the oscilloscope time/division as necessary.
17. Check that the sine wave generator frequency is ≥60 MHz.
When you are done, disconnect all test equipment and replace the termination
cover.
