8. 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 vertically for the grid. However , by using the
automatic scaling function, you can obtain the optimum vertical
setting.
1. Press 4 Chan 1 5 to activate channel 1.
2. Press 4 Scale Ref 5 .
3.
Press
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
AUTO SCALE to scale the trace of channel 1.
4. Press 4 Chan 2 5 to activate channel 2.
5.
Press
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
AUTO SCALE to scale the trace of channel 2.
If you want to change scale manually , press 4 Scale Ref 5

turn the rotary knob or input scale value as required.
Y ou will get the measurement results shown on the rst page of this
chapter .
9. Analyzing a
Measurement
Result
If you can obtain the correct trace on the display , you can analyze a
measurement result by using the marker .
Using the Marker
Marker functions allow you to read out the trace values and the
frequency , and also to move to a specic point (for example , the
maximum, the minimum, or the peak point). In this procedure ,
reading a measured value and moving the marker to the maximum
point is demonstrated.
Reading a Measured V alue
1. Press 4 Ma rk er 5 .
2. Turn the rotary knob until the marker moves to the point where
you want to read the measured value .
3. Read the marker value displayed on the upper right of the display .
