right side. Firstly Select “ +/- ”,and then input the antenna gain on
numeric keyboard.
The item in the middle decides the refresh time of reading in levels of
FAST, MIDDLE and SLOW. MIDDLE is recommended. The refresh
time of Table S not disturbed by the setting is used to observe
instantaneous changes of signal intensity.
Warning
KC901S is a network analyzer which does not prevent the reveal of local
oscillation. When it is used to observe spatial frequency spectrum and
field strength, local oscillation signal will flow backwards to receiving
antenna. The strength may arrive -10dBm, and the frequency will be
45MHz higher or lower as the receiving frequency. Consider
consequences are caused by the sending signal, and take some measures
for protection. Always switch unit off or press stop to prevent other
systems from RFI when you have finished measurements!
2.9 Insertion Loss Mode
Insertion loss is the system of single frequency point of S21. It is an
essential measurement of S21, whereas only a single point frequency is
measured.
After entering the FIELD test mode, Insertion on the right of the menu
means starting signal input. Get to GEN ON into the display of insertion
