18. On the 83504 press a
19. Adjust A7R65 "LO" (low end of band) to again place the third crystal marker exactly 0.4
divisions to the left of the
8350A amplitude marker. It may be necessary to fine adjust
the oscilloscope horizontal position control to reset the
8350A amplitude marker to the
reference graticule selected in step 17.
20. Rotate the
8350A FREQUENCYITIME vernier to change the sweep time from 10
milliseconds to 0.5 seconds. The spacing between the
8350A amplitude marker and the
crystal marker used should not vary greater than
f 5 MHz from its original position set
in step 17 (determined by
+1/10 the distance between 50 MHz markers).
On the
83504 press
#p .
22. Adjust the oscilloscope HORIZONTAL POSITION control to look at the highest
frequency crystal marker possible (up to 2.4
GHz).
NOTE
The highest frequency marker available may be limited by the gain of the
oscilloscope horizontal deflection amplifiers when used in the
XI0
magnification mode. Sufficient accuracy may be obtained by using any
marker greater than
1.6 GHz.
23. On the 83504 press
. Rotate the 8350A FREQUENCYITIME vernier to place the
marker near center screen on the oscilloscope. Temporarily removing the oscilloscope
from
XI0 magnification will aid in finding and moving the marker. Reset the oscilloscope
to
XI0 magnification before proceeding.
24. On the
83504 press
. Rotate the VERNIER to place the desired
crystal marker exactly 0.4 divisions to the left of the leading edge of the
8350A
amplitude marker as shown in Figure 5-15. It may be necessary to fine adjust the
oscilloscope horizontal position control to move the leading edge of the
8350A
amplitude marker to a convenient graticule which may then be used as a point of
reference.
On the
83504 press P
26. Adjust A7R66 "HI" (high end of band) to again place the crystal marker selected in step
24 exactly 0.4 divisions to the left of the
8350A amplitude marker. A slight readjustment
of the oscilloscope horizontal position control may again be necessary.
27. Rotate the
8350A FREQUENCYITIME vernier to change the sweep time from 10
milliseconds to 0.5 seconds. The spacing between the
8350A amplitude marker and the
crystal marker used should not vary greater than
f 5 MHz from its original position set
in step 24 (determined by
+1/10 the distance between 50 MHz markers).
