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.

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.

Averaging Status

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

Bandwidth Parameter

It shows the bandwidth data for a trace when the bandwidth function is turned on.

Calibration/Compensation/Port Extension Status

Calibration Status

Compensation Status

When the span is narrowed from the span of compensation in "user point", ? is displayed after COMP, like COMP? OSL.

Port Extension Status

PEXT or PExt is displayed when Port Extension is turned on and Length or Time is not zero.

• PEXT: Fixed point

• PExt: User point

Channel Number

Indicates the channel number. To make a channel active, use Channel Next or Channel Prev. Clicking inside a channel window will also make the channel active.

Channel Measurement Status

Displays the update status of traces on the channel.

Channel Title Bar

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

DC Monitor

DC Monitor values are displayed when the DC monitor function is turned on.

Equivalent Circuit Model/Simulation Result

Equivalent Circuit Model/Simulation Result are displayed for the equivalent circuit.

Graticule/Scale 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 Values

The marker stimulus and response values for each marker 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 Statistic Parameters

It shows the statistics data for a trace (span, mean, standard deviation, and peak-to-peak) when the statistic function is turned on.

Measurement Parameter

Measurement parameters are displayed.

OSC Level/DC Bias/CW Frequency

Indicates the OSC level, DC Bias and CW frequency in the following conditions.

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

The scale for each trace is displayed here.

• When Linear scale is selected at Y-Axis
  The scale/Div and Reference values are displayed.
  This example shows that "50.00°" corresponds to 50° per division. "Ref 0.000°" shows that the value of the reference line is 0°.

• When Log scale is selected at Y-Axis
  The top and bottom values of Y-Axis are displayed.

Sweep Range

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

Trace Number

The names of the traces, such as Tr1, on the channel are displayed here. The symbol  at 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.

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.
