box with a progress bar. After completing the sweep the analyzer
generates a short sound and a green checkmark appears in the
checkbox.
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 coefficient, and change the display format to obtain information about the
phase shift of the reflected wave and the impedance of your DUT.
1. Press the MKR function key. 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 the MKR --> function key, open the
Marker Search
submenu
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 coefficient 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.
