9. Measuring the
MUT
After you place the MUT on the test xture , the measured result is
displayed.
P erforming A utomatic
Scaling
Often, the trace obtained after specifying the frequency range is
too large or too small for the grid. However , by using the automatic
scaling function, you can obtain the optimum scale setting.
1. Press 4 Chan 1 5 or 4 Chan 2 5 to activate the required channel.
2. Press 4 Scale Ref 5 .
3.
Press

rotary knob or input scale value as required.
Using the Marker
Marker functions allow you to read out the trace values and the
frequency . They also allow you to move the marker to a specic point
(for example , the maximum, the minimum, or the peak point). This
procedure shows you how to read a measured value . See \Searching
for a Specic P oint" in Chapter 6 for information on how to search
for a specic point.
