Evaluating Data
The analyzer provides various tools to optimize the display and analyze the mea-
surement data. For instance, you can use markers to determine maxima and min-
ima on the trace, and change the display format to obtain information about the
group delay of the transmitted wave.
1. Select [Mkr] > [Mkr] > "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 corner of the diagram. The marker info field displays the stimulus value
(frequency) and response value (magnitude of the transmission coefficient
converted to a dB value) at the marker position.
2. Open the [Mkr->] > "Peak" softtool tab 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 posi-
tion.
3. Select [Format] and choose the "Delay" of the transmission coefficient as dis-
played quantity.
The group delay represents the propagation time of the wave through the
DUT; it is displayed in a Cartesian diagram. The marker info field shows the
frequency and group delay at the marker position.
