Setting the Layout of Windows and Graphs

You can split the E5071C's LCD screen into multiple windows that display channel-specific result information, and the window layout can be selected from a number of variations. In addition, you can place on screen a segment sweep table or echo window, which you can use to display messages from your custom program.

Selecting the window layout (Channel Display Mode)

One window displays the results for a single channel. You cannot have a single window display the results from more than one channel. This means that setting the window layout determines the number of channels displayed on screen.

To select one of the 19 different window layouts shown in the figure below, use the following command:

:DISP:SPL

Selecting the graph layout (Trace Display Mode)

You can place a number of trace graphs in each window by selecting one of the pre-defined graph layouts. The number of graphs differs depending on your selected graph layout. If the number of graphs is equal to or larger than the number of traces (set by the :CALC{1-36}:PAR:COUN command), each graph always displays one trace. On the other hand, if the number of graphs is smaller than the number of traces, some of the graphs display two or more traces. Graph 1 is populated with trace 1, graph 2 with trace 2, and so on. Traces whose numbers exceed the last graph's number will populate graph 1, graph 2, and so on.

To select one of the 19 different graph layouts shown in the figure below, use the following command:

:DISP:WIND{1-36}:SPL

Maximizing a window or a trace graph

When you have multiple windows displayed, you can maximize the active channel window so that it covers the entire screen area. To maximize a window, use the following command:

:DISP:MAX

Similarly, when you have multiple traces displayed, you can maximize the active trace so that it extends throughout the entire window. To maximize a trace, use the following command:

:DISP:WIND{1-36}:MAX

Window/graph layouts and command parameters

Showing/hiding a table or echo window

You can display the following items at the bottom of the LCD screen:

Segment sweep table
Limit table
Marker list table
Echo window (a window that displays messages from a custom program)
Loss compensation table
Power sensor's calibration factor table

To show or hide each of the above items, use the following command:

:DISP:TABL

You cannot have two or more of the above items displayed at a time. The screen displays only the selected item by using the following command:

:DISP:TABL:TYPE

Showing/hiding softkey labels

You can show or hide the softkey labels placed alongside the right-hand edge of the LCD screen. To show or hide the softkey labels, use the following command:

:DISP:SKEY

Configuring Trace Display Settings

Selecting which traces to display

Each trace has two different representations: data and memory traces. You can show or hide the data and memory traces independently of each other. To show or hide the data or memory traces, use the following commands:

Type	Command
Data trace	:DISP:WIND{1-36}:TRAC{1-36}:STAT
Memory trace	:DISP:WIND{1-36}:TRAC{1-36}:ANN:MARK:POS:X

To copy the data trace to the memory trace, use the following command:

:CALC{1-36}:MATH:MEM

Configuring cross-trace math operations

You can perform math operations between the data and memory traces and have the results displayed as the data trace. To perform cross-trace math operations, use the following command:

:CALC{1-36}:MATH:FUNC

Configuring smoothing settings

To turn on/off smoothing, use the following command:

:CALC{1-36}:SMO

The smoothing aperture is expressed as a percentage with respect to the sweep range. To set the smoothing aperture, use the following command:

:CALC{1-36}:SMO:APER

Selecting the data format

You can select the following data formats:

Rectangular display formats
- Log magnitude format
- Phase format
- Group delay format
- Linear magnitude format
- SWR format
- Real format
- Imaginary format
- Expanded phase format
- Positive phase format
Smith chart format
Polar format

To select the measurement parameter data format, use the following command:

:CALC{1-36}:FORM

Configuring the display scale

Depending on the measurement parameter data format, you can configure the display scale in one of the following two ways:

Rectangular display formats:

When you use one of rectangular display formats (Logarithmic magnitude/Phase/ Group delay/Linear magnitude/SWR/Real/Imaginary/Expanded phase/Positive phase), you can configure the display scale by setting the following four items:

Type	Command
Number of divisions	:DISP:WIND{1-36}:Y:DIV
Scale per division	:DISP:WIND{1-36}:TRAC{1-36}:Y:PDIV
Reference graticule line	:DISP:WIND{1-36}:TRAC{1-36}:Y:RPOS
Reference graticule line value	:DISP:WIND{1-36}:TRAC{1-36}:Y:RLEV

The number of divisions is a channel-wide setting (shared among all traces), while the remaining three settings are trace-specific.

You can show or hide graticule label (the label on the left-hand side of the graticule lines) by issuing the following command:

:DISP:WIND{1-36}:LAB

Smith chart/Polar formats:

When you are using one of Smith chart/Polar formats, you can only set the full scale value (the outermost circle's value) using the following command:

:DISP:WIND{1-36}:TRAC{1-36}:Y:PDIV

Auto Scale

You can use Auto Scale to automatically set the display scale. This feature works by automatically adjusting the reference division line value and the scale value per division when you are using one of the rectangular display formats or the full scale value when you are using one of Smith chart/Polar formats.

To perform Auto Scale, use the following command:

:DISP:WIND{1-36}:TRAC{1-36}:Y:AUTO

Displaying a message in the echo window

You can display a message in the echo window by issuing the following command:

:DISP:ECHO

You can clear any message displayed in the echo window by issuing the following command:

:DISP:ECHO:CLE

Turning On/Off display update

To turn on/off the update of the LCD screen, use the following command:

:DISP:ENAB

Showing/hiding frequencies

To show or hide frequencies on the LCD screen, use the following command:

:DISP:ANN:FREQ

Showing or hiding the title

To show or hide the title, use the following command:

:DISP:WIND{1-36}:TITL

To define the title string that appears in the title display area, use the following command:

:DISP:WIND{1-36}:TITL:DATA

Configuring date/time display

To show or hide the current date and time on the right-hand side of the instrument status bar, use the following command:

:DISP:CLOC

To set the date and time, use the following command:

:SYST:DATE

:SYST:UPR

Turning On/Off the LCD backlight

To turn on/off the LCD backlight, use the following command (note that turning off the backlight makes the screen unreadable):

:SYST:BACK

Setting Display Color

Selecting Display Mode

You can select the one of two LCD display modes: normal display (black background) or inverted display (white background).

To select the display mode, use the following command:

:DISP:IMAG

Setting display color for each item

To set the display colors, use the following commands:

Data trace	:DISP:COL{1-2}:TRAC{1-36}:DATA
Memory trace	:DISP:COL{1-2}:TRAC{1-36}:MEM
Graph	:DISP:COL{1-2}:GRAT{1-2}
Limit test	:DISP:COL{1-2}:LIM{1-2}
Background	:DISP:COL{1-2}:BACK

Resetting display colors to factory state

You can reset the display colors in normal display and inverted display to the preset factory state.

To reset the display colors, use the following command:

:DISP:COL{1-2}:RES
