MODE button is for function selection. Function can be switched by pressing
MODE repeatedly. In most situations, user can switch back to the function
menu/function selection menu by just pressing MODE, it can be used as a HOME
button.
The typical application of
wave and impedance. For this, choose the port which is on right side.
Reflection is measured in vector. It has various ways to display and can be chosen
through FORMAT menu. When showing Smith chart and the impedance, the soft
menu from the second left can provide more ways to display.
Access: MODE and then choose the item of reflection test (S11) in the menu.
The typical application of transmission measurement (S21/12) is to test the fil-
ter and the amplitude-frequency characteristic chart. For this, both two N type RF
ports need to be used. Signal outputs from instrument's left port and inputs from the
right port.
Access: MODE and then choose item S21.
Attention
While performing transmission measurement, the flow direction of the signal is
opposite to the reflection measurement. It's also different from the usual network
analyzer. While testing the asymmetric elements, adjusting elements' directions
manufactoringly is needed.
Insertion Loss Measurement is a form of single frequency transmission meas-
urement. So user can adjust the devices under test quickly with its fast update rate. It
can be used for accurate filter adjustment as well as measuring the gain of antenna.
In order to maintain the consistency with the operating habits of other instru-
ments, turn-on/off setting of insertion loss measurement function is in field strength
mode.
Access: press MODE(then choose PAGE DOWN), choose FIELD in the menu, then
choose Insertion. You will see that "GEN ON" on the right down of the screen.

and interference. It can also be used to test RF circuits, search hidden emission
source with KC-R100 directional antenna. The right-hand-side port should be used in
this situation.
Access: Press MODE and then choose SPEC in the menu.
