Two-port measurements with the tracking generator
R&S FSH
1145.5973.12 4.90
E-14
Measuring the transmission magnitude
Connect the DUT between the tracking generator
output and the RF input.
Press the MEAS MODE softkey.
Using the rotary knob or the cursor keys, select
MAGNITUDE from the menu and confirm by
pressing either the MEAS MODE softkey or the
ENTER key.
The R&S FSH will indicate the transmission magnitude
and the message Magnitude transm. in the upper
right-hand corner of the display.
Measuring the transmission phase
Press the MEAS MODE softkey.
Using the rotary knob or the cursor keys, select
PHASE from the menu and confirm by pressing
either the MEAS MODE softkey or the ENTER key.
The R&S FSH displays the DUT's phase characteristic
as a function of the frequency. Phase transm. will
appear in the upper right-hand corner of the display. In
the default scaling, the phase can only have values
between -180° and +180°.
Note:
In the diagram's default scaling of -180° to
+180°, the trace will be shown correctly only if the
phase difference between two adjacent test points is
less than 180°.
