Measurement Window

This provides windows for displaying traces. Because a measurement corresponds to a window, it is called a measurement window. When the outer frame of a measurement window is displayed in light gray, the measurement is active (the measurement for which setup is being performed). In Measurement Window spectrum window is active. To make a measurement active, use Window Next . Clicking inside a measurement window will also make it active. The following figure shows example of a spectrum measurement displayed in maximum screen by using Window Max.

4-1. Measurement Title

You can assign a title to each channel and have the title displayed in the bar. To set up the measurement title, enter a title in Display > Edit Title Label and then toggle on/off the title display by using Display > Title Label .

4-2. Trace Name

The names of the traces on the measurement are displayed here. to the left of the trace name indicates the active trace (the trace for which setup is being performed). To switch over the active trace, use Trace A series of data points containing frequency and response information. The series of data points is often called an array. The number of traces is specific to the instrument. Next. Clicking the graph of the trace will also activate the trace.

4-3. Scale Settings

The scale setting for each trace is displayed here. This example shows that “0.00dB/” corresponds to 10 dB Decibel: a relative unit of measure. The ratio in dB is given by: 10 log10 (P1/P2) where P1 and P2 are the measured powers. The dB is preferred instead of arithmetic ratios or percentages because when components are connected in series, their effect on power, expressed in dB, may be arithmetically added and subtracted. For example, if a 3dB attenuator is connected to a 10dB amplifier, the net gain of the two components is (-3dB + 10dB = +7dB). per division. “Ref -50.00.000dB” shows that the value of the reference line is -50 dB. To specify the scale settings, use each softkey that can be displayed by pressing the Scale hardkey.

4-4. Trace Status Area

The setup for each trace is displayed here.

4-5. Reference Line Indicators

These indicate the position of the reference line for the Y-axis scale in the rectangular display format. There is an indicator to the right of the scale (). To enter a numeric value for the position of the reference line, open the data entry bar using the keys Scale > Reference Position. You can also move the position of the reference line by placing the mouse pointer on the reference line indicator (the pointer changes from to . ), moving the indicator vertically with the left mouse button kept pressed, and then releasing the button at the desired location (i.e., a drag-and-drop operation).

4-6. Measurement Status Bar

The status of each measurement is displayed here.

4-7. Measurement Status

Displays the update status of traces on the measurement.
 

4-8. Averaging Status

Displays the averaging factor and averaging count when averaging is turned on.
 

4-9. Sweep Range

Indicates the sweep range by using the start/stop or center/span. This varies depending on the given parameters or measurements.

4-10. Measurement Name

Indicates the measurement name.

4-11. Measurement Parameters

Indicates the parameters specified to perform a measurement sweep at the bottom of each measurement screen. The content may vary depending on the measurement.

4-12. X-axis Labels

X-axis divisions in the rectangular display format. To hide the divisions, select "OFF" in -Y # of Digits. (The display/nondisplay of the X-axis divisions interlocks with that of the Y-axis divisions.)

4-13. Y-axis Labels

Y-axis divisions in the rectangular display format. The value of the reference line (the division line indicated by ) can be entered numerically by opening the data entry bar using the keys: Scale > Reference Value. You can change values of the reference line in one division intervals by placing the mouse pointer in the area of the graticule label (the pointer changes fromto ), moving the pointer vertically with the left mouse button pressed, and then releasing the button at the desired location. By using Display > Y # of Digits, you can select the display format of the graticule label from three options: 4 digits, 12digits, and “not displayed.”

4-14. Marker Information

The marker information is displayed in a list. It shows the marker number, marker x-axis value, and marker measurement value from left to right. For the active marker (the one for which setup and analysis are being performed), > is displayed to the left of the marker number. For the reference marker,Δ is displayed instead of the marker number.

4-15. Statistics Data

Turning on the statistics data function displays statistics data here. For more about the statistics data function, see Determining Mean, Standard Deviation, and Peak-to-Peak of the Trace

4-16. Markers

The markers used for reading values on a trace. Up to six markers can be displayed for each trace.

Here, n denotes a marker number. For the reference marker, however, nothing is displayed at the location of n. Clicking the marker or one of the Marker A graphical symbol along a display trace that is annotated with measurement characteristics of that specific data point. Indicators makes the marker active.

4-17. Marker Indicators

These indicate the positions of markers on the x-axis.

You can also move a marker to desired position by placing the mouse pointer on marker indicator or the position of the marker itself (the pointer changes fromto ),moving the indicator vertically with the left mouse button pressed, and then releasing the button at the desired location.

4-18. X-axis Bandmarkers

By turning on the x-axis band marker function, the x-axis band marker is displayed in a specified position.

You can also move a marker to the desired position by placing the mouse pointer on the marker indicator or the position of the marker itself (the pointer changes from to ),moving the indicator vertically with the left mouse button pressed, and then releasing the button at the desired location.

4-19. Y-axis Bandmarkers

By turning on the y-axis band marker function, the y-axis band marker is displayed in a specified position

You can also move a marker to the desired position by placing the mouse pointer on the marker indicator or the position of the marker itself (the pointer changes from to ), moving the indicator up or down with the left mouse button pressed, and then releasing the button at the desired location.

4-20. Bandmarker information

Turning on the x-axis or y-axis band marker function will display the corresponding band marker information on a list in the order of start, stop, center and span.
