7. Set the vertical SCALE to 10 mV/div.
8. Set the generator output so the CHx Pk-Pk readout equals 60 mV.
9. Press SET LEVEL TO 50% as necessary to trigger the display.
10. Increase the frequency of the generator output to 100 MHz (TDS 340),
200 MHz (TDS 360), or 400 MHz (TDS 380).
11. Set the horizontal SCALE to 5 ns/div (TDS 340), 2.5 ns/div (TDS 360), or
2.5 ns/div (TDS 380).
12. Press SET LEVEL TO 50% as necessary to trigger the display.
13. Check that the Pk-Pk readout on screen (as shown in
Figure 4–7) is
w
42.5 mV.
Second, read the results
from the readout of
measurement Pk-Pk.
First, increase the reference
frequency to the test frequency;
then decrease the horizontal
scale.
