Measurement Diagram

Access:

 

Select "RF > Configure > NRP-Z Power Analysis".

The dialog contains the measurement diagram with the "Start" button. It provides access to the dialogs for setting up the measurement and sensor parameters, for configuring the diagram and trace indication, and for storing hardcopies of the measurement results.

The R&S SMA supports various graph views, according to the methods of measurement and also additional functions such as the use of markers.

Note: Activate the relevant diagram views in the "REARR list NRP-Z Analysis" dialog, see "REARR list - Power Analysis", and switch to the currently needed view with the aid of the REARR key or STR+<A>.

Markers and the marker list are available in the "NRP-Z Analysis Frequency / Marker" view which is shown in the graph above (see also "Define Markers"). Select a marker with the roll key. One click activates the cursor, the second click captures the selected marker to move it to the desired position. Set the focus back to the diagram with a double click on ESC.

The list below the diagram displays the numerical readout of the marker values.

The x-axis of the measurement diagram is freely scalable in the frequency or power range of the generator, the power range for the y-axis is +100 dBm to -200 dBm. In power versus frequency mode, the frequency range of the x-axis is separately scalable. The available time range for power versus time measurements is -1s to +2s.

It is possible to select single or continuous measurement mode in the "Config…" menu. Single starts a single measurement after the trigger, continuous causes a restart of the measurement after each pass. The measurement is triggered by pushing the "Start" button. In continuous mode, the "Start" button is replaced by a "Stop" button after the trigger which can be used to cancel the measurement. A progress bar indicates the status of the measurement.

In time mode, additional triggering is required which is configured in the trigger dialog.

Changing to trace source "Hold" freezes the current trace indication in the diagram.

Some front panel keys are assigned special functions if the power analysis is active (see overview of features and operation in section "NRP-Z Power Analysis"):

Marker and Pulse Data Indication - Power Analysis

The marker and pulse data value indication below the measurement diagram is only available for certain views of the diagram. The REARR key or the key combination <STR+A> toggles between the different diagram views (see "NRP-Z Power Analysis"). The marker indication in the measurement diagram is activated in the marker dialog, see "Define Markers".

Tip: In remote-control mode, include the markers of the diagram, their values or the pulse data in the hardcopy file.
