Basic Operations for RF Devices Measurement
STEP 8. Measuring DUT and Analyzing Measurement Results
Simulating Frequency Characteristics
We can simulate the frequency characteristics of Trace 1 (|Z|) by using the approximate
value obtained by the above calculation based on the setup example of "(1) Frequency
Characteristics of |Z|-Ls-Q" on page 46.
NOTE
Simulation can also be done by inputting a desired value in the parameter box of an
individual equivalent circuit model.
Step 1. Click
Step 2. Specify Trace 1 (|Z|) as the active trace (* mark) as shown in Figure 3-9 and Figure 3-10.
Step 3. Click the
Trace 1 (|Z|). The simulated data are traced on the display screen (Figure 3-83).
NOTE
Clicking the
toolbar simulates the frequency characteristics of all traces.
Enlarging Trace (Zoom Function, Mouse Operation Only)
The mouse can be used to select a range for enlarged display. This zoom function is
accomplished by the following steps. Here, the zoom function is performed by using the
example shown in Figure 3-61, "(2) Frequency Characteristics of |Z|-R-X," on page 84.
Step 1. Select the range to be enlarged by dragging with the mouse (Figure 3-84).
NOTE
"Drag" means a series of operations including moving the mouse pointer while pressing
and holding the mouse button to select a desired range before releasing the button.
Step 2. The selected area on the display is enlarged (Figure 3-84).

Step 3. Click the mouse on the screen to clear the zoomed image and return the display to the
previous standard size.
