5-3 Measurement Setup

5-3 Measurement Setup
Before conducting a measurement, ensure that the instrument is set to Field measurements
view. Then select a measurement type, specify the frequency range and sweep parameters
(such as number of data points), and perform a calibration. These operations are described
further in the following paragraphs. This chapter describes the Field measurements view.
Note that the VNA measurements view is the default measurement display type that is
described in the other chapters of this measurement guide.

the instrument calibration.
You can save a Setup with calibration (refer to the file management instructions in the user
guide for your instrument). In the Save menu, press the Change Type soft key to open the
Select File Type list box. Scroll to Setup (with CAL) and press the Enter key (refer to the file
management instructions in the user guide for your instrument).
When you recall a setup, the calibration remains valid if instrument conditions (such as
temperature) remain within the calibration tolerance.

Measure (4) key. All available VNA measurement types are found in the Graph Type Selector
list box (which is opened by pressing the Measurement Type soft key in the Measure menu).
DTF Return Loss and DTF VSWR measurements are standard.

Setting the Frequency Range

Regardless of the type of measurement that is being made, the frequency range for the
desired measurement must be set before calibrating the instrument. Increasing the frequency
after calibrating the instrument will invalidate the calibration. Decreasing the frequency
does not invalidate the calibration. Press the Freq/Dist function hard key (below the sweep
window) to display the
