Using the Multiport Test System
How to Use Markers
Select Markers Active to turn markers on. Inside the plot area, point at the trace with
cursor and click the left mouse button. While holding the left mouse button down, move the
mouse to select the desired frequency. The instant readout marker function shows the marker
value at any frequency.
The frequency display is in MHz to the left, with the data value to the right. In displays with
a large number of data points, hold down the shift key while moving the mouse for greater
placement accuracy.
To place a marker, hold the left mouse button while clicking the right button. Note that you do
not have to place the mouse pointer on or even near the trace; the frequency (horizontal)
position of the pointer is used to position the marker.
