44. Check the at the 3 points for both the LO
and On the scalar network analyzer, press Max. Press
cursor A (ON) and set the cursor at the -3 point fO.l Press
cursor A, cursor A, and set the cursor to the corresponding -3
point on the opposit side of the signal. The cursor should now
read 0 fO.l
45. On the synthesized sweeper, press and place the marker on
either cursor A. Press and place the marker on the cursor A
on the opposite side of the trace.
46. On the synthesized sweeper, press and read the
shown on the ENTRY DISPLAY. Press OFF. See
Figure 3-74 and Figure 3-75.
47. Disconnect the detector from cable 80 (gray/black) and connect
cable 92 (white/red) from IF) to the scalar network
analyzer’s A input.
