15. Record the resu
lts in the test record and compare the results against the high
frequency specification. (See Table 1 on page 9.)
16. Set the P6022 t
ermination sensitivity to 10 mA/mV.
17. Set the oscilloscope Vertical Deflectionto2mV/div.
18. Set the oscilloscope Horizontal Scale to 10 μs/div.
19. Set the Leveled Sinewave Output of the calibration generator to 50 kHz and
an amplitude of 5 V
pp
.
20. Measure and record the oscilloscope amplitude Auto Measurement as M3 in
the table.
21. Set the oscilloscope Horizontal Scale to 4 ns/div or 5 ns/div.
22. Set the Leveled Sinewave Output of the calibration generator to 120 MHz.
23. Measure and record the oscilloscope amplitude Auto Measurement as M4 in
the table.
24. Calculate the high frequency bandwidth ratio:
25. Record the results in the test record and compare the results against the high
frequency specification.
When you are done, disconnect all test equipment and replace the termination
cover.
