42 V Range (÷ 50).
8. Set the probe to the 42 V range (÷ 50).
9. Change the reference value on the network analyzer to keep the plot on screen (–34 dB).
10. Using the marker (if equipped), measure the output amplitude at 500 MHz for the P6250 or 1 GHz for the P6251.
11. Verify that the amplitude is greater than –37 d B . (Subtracting the –34 dB of probe attenuation in the 42 V range from the
–37 dB target value yields the –3 dB limit.) Record the results in the test record.
12. Retain the setup for the next test.
