6. Click "Apply" to close the wizard, calculate and store the system error correction data
and apply them to the current measurement.
7. Remove the short standard and connect the DUT again.
2.1.4 Evaluation of Data
The analyzer provides various tools to optimize the display and analyze the measurement
data. For instance, you can use markers determine the maximum of the reflection coef-
ficient, and change the display format to obtain information about the phase shift of the
reflected wave and the impedance of your DUT.
1. In the TRACE keypad, press MARKER. This places "Marker 1" to its default position
(center of the sweep range).
A marker symbol (triangle) appears on the trace. The stimulus value (frequency) and
response value (magnitude of the reflection coefficient converted to a dB value) at
the marker position is displayed in the marker info field in the upper right corner of
the diagram.
2. Press MARKER FUNCT and activate "Min Search".
The marker jumps to the absolute minimum of the curve in the entire sweep range.
The marker info field shows the coordinates of the new marker position.
3. In the TRACE keypad, press FORMAT and select the "Phase" of the reflection coef-
ficient to be displayed.
The phase is shown in a Cartesian diagram with a default vertical scale of 225 deg
to +225 deg. The marker info field shows the frequency and phase at the marker
position.
4. Still in the FORMAT menu, select "Smith".
