7. The calibration dock widget indicates the standard measurements that make up a
"Trans Norm" calibration.
Select "Through (mm)" to initiate the measurement of the connected Through stan-
dard. Measuring the isolation between ports 1 and 2 is optional. Skip it for now.
The analyzer performs a calibration sweep for the measured quantity S
magnitude and phase of the result is displayed in two diagrams, together with the
expected typical result for a Through standard. The similarity of real and expected
traces indicates that the Through standard has been properly connected. After the
R&S ZNB/ZNBT has completed the calibration sweep and calculated the correction
data, the "Apply" button is enabled.
8. Select "Apply" to close the wizard.
The system error correction is calculated and applied to the current channel. A
"Cal" label appears in the trace list.
To proceed with the measurement, remove the Through standard and connect the DUT
again.
3.4.1.4 Evaluating data
The analyzer provides various tools to optimize the display and analyze the measure-
ment data. For instance, you can use markers to determine maxima and minima on the
trace, and change the display format to obtain information about the group delay of the
transmitted wave.
1. Select Trace – [Marker] > "Markers" > "Mkr 1".
This places marker "M1" to its default position (center of the sweep range). A
marker symbol (triangle) appears on the trace, a marker info field in the upper right
