Channel Window

Window for displaying the traces. Because a channel corresponds to a window, it is called a channel window. When the outer frame of a channel window is displayed in light gray, it shows that the channel is an active channel (the channel for which setup is being performed). In the following figure, Channel 1 (the upper window) is the active channel. To make a channel active, use Channel Next or Channel Prev. Clicking inside a channel window will also make the channel active.

Channel 1 Window and Channel 2 Window describes different measurement parameters available in the channel measurement window. The measurement parameters described in the Channel 1 and 2 Window correspond to the same channel measurement window and are displayed in separate windows for ease of read.

Bandwidth Parameters

Turning on the bandwidth search function displays the bandwidth parameters here.

Channel Number

Indicates the channel number.

Channel Status Bar

The status of each channel is displayed here.

Averaging Status

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

Channel Measurement Status

Displays the update status of traces on the channel.

Error Correction Status

Displays the execution status of error correction on the channel.

IF Bandwidth/CW Frequency

Indicates the IF bandwidth when the sweep type is linear/log frequency or the CW frequency when the sweep type is power.

Port Extension Status

Shows whether the port extension and impedance port extension (Option 005 only) or is turned ON or OFF. port extension and impedance port extension can be truned on both at the same time.

Sweep Range

Indicates the sweep range by using the start/stop or center/span.

Channel Title Bar

You can assign a title to each channel and have the title displayed on the bar.

Data Format

The data format of each trace is displayed here.

Graticule Labels

Y-axis divisions in the rectangular display format. When traces in the rectangular display format are overlaid, the Y-axis divisions for the active trace are displayed. The value of the reference line (the division line between and ) is entered numerically by opening the data entry bar using the keys:  Scale > Reference Value. You can change values of the reference line at one-division intervals by placing the mouse pointer in the area of the graticule label (the pointer changes from to ), moving the pointer vertically with the left mouse button pressed, and then releasing the button at the desired location.

Marker Indicators

Indicates the positions of markers on the stimulus axis.
 

You can also move a marker to the desired position by placing the mouse pointer on the marker indicator or 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.

Marker Numbers

Displayed marker number is listed. For the active marker (the one for which setup and analysis are being performed), > is displayed at the left of the marker number. For the reference marker, is displayed instead of the marker number.

Marker Response Values

The marker response value for each marker (the measurement value at the marker point) is displayed here. Two (or three) response values are displayed for data in Smith chart or polar display format.

Markers

The markers used for reading values on a trace. Up to 10 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 Indicators makes the marker active.

Marker Stimulus Values

The marker stimulus value for each marker (the frequency/power level at the marker point) is displayed here.

Properties

Displays the status of the obtained calibration coefficients on the channel.

Reference Line Indicators

The indicators that indicate the position of the reference line for the Y-axis scale in the rectangular display format. One indicator is to the right and the other is to the left of the scale ( and ). 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 either of the two reference line indicators (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).

Scale Settings

The scale setting for each trace is displayed here. This example shows that "10.00dB/" corresponds to 10 dB per division. "Ref 0.000dB" shows that the value of the reference line is 0 dB.

Statistics Data

Turning on the statistics data function displays statistics data here.

Trace Name/Measurement Parameter

The names of the traces, such as Tr1, on the channel and their measurement parameters are displayed here. to the right of the trace name indicates the active trace (the trace for which setup is being performed). To make a trace active, use Trace Next or Trace Prev. Clicking the line where the trace name is placed (the mouse pointer changes from to ) also makes a trace active.

Trace Number

In the rectangular display format, the trace number is displayed in the same color as the trace at the right end of each trace.

Trace Status Area

The setup for each trace is displayed here.

Trace Parameter Display

As mentioned above, measurement parameters are displayed at the upper-left of the trace window. However, there is difference in parameter display for network measurement and impedance measurement.

Network Measurement

When network measurement is selected, for example, S11, the following parameters are displayed at the upper-left of the trace window:

Impedance Measurement (Option 005)

When impedance measurement is selected, the measurement parameter and format is replaced with Z-parameter and measurement method. Hence, the following parameters are displayed:

Y-Axis (Log)

Regardless of the measurement parameter, when Log scale is selected at Y-Axis, the following parameters change.

If Linear scale is selected:

If Log scale is selected:

Example

Below are examples of several scenarios.
