Basic Operations for RF Devices Measurement
STEP 8. Measuring DUT and Analyzing Measurement Results
Adjusting Scale
When a trace is formed flat, executing auto scale makes the scale value of the grid smaller
so that the overall trace can be monitored on the full screen (Figure 3-62 and Figure 3-63).
To change the scale to a desired value, adjust it by following these steps. In this section, the
scale is adjusted by using the setup example of Figure 3-62, "(3) Oscillator Level (Current)
Characteristics of Ls-Q," on page 85 (when the display format is linear).
NOTE
Scaling parameters for the adjustment vary according to the display format. For details
about scaling parameters, refer to Chapter 5, "Display Setting" in the E4991A Operation
Manual.
