Data Scrolling

The chart display acts like a strip chart recorder where the pen is drawing the most recent data. For example, if the sample rate is 1 Hz (1 point taken per second) and the horizontal scale is 10 S/div, then the graph displays 100 data points (10 divisions x 10 points per division). As new data is taken, the old data scrolls to the left at the rate of 10 S/div. This is because new points are added at a fixed location (right edge of the graph) just like a strip recorder. In this case, the time value of the right most point is 0.000 S meaning the most recent data point.

The chart displays a fixed window in time which is 10 divisions wide (100 seconds in this case) start- ing Tright seconds ago (where Tright is the time value of the right most point). Since the data is always getting older, it scrolls left continuously (whenever data is being taken).

Cursor

The cursor region is the graph region between the two heavy vertical dashed lines. The cursor region may be set to 1 division (wide), 1/2 division (norm), or a single vertical line (spot). The cursor region does not change with horizontal scaling. The cursor is the small square which seeks the minimum, maximum, or mean of the data within the cursor region. When seeking min or max, the cursor is located at the position of the data point which is the min or max. This allows peaks and valleys in the data to be easily specified. When seeking the mean, the X position of the cursor is at the center of the cursor region and the Y position is the mean of the data within the region. The cursor type is defined in the CURSOR SETUP menu.

Often the display is scaled such that there are many more data points than can be resolved on the display. The chart display is 496 pixels wide. If more than that number of data points are being displayed, then each horizontal position repre- sents multiple data points. In this case, a vertical line is drawn between the minimum and maximum data points represented by a single horizontal location. In this case, even the spot cursor region represents multiple data points. The cursor will seek the max, min or mean of these data points.

Pressing the [CURSOR] key will draw a box around the cursor readout of the active chart dis- play. Use the [ACTIVE DISPLAY] key to select the

desired display (top or bottom). When the cursor readout is surrounded by this box, the knob adjusts the position of the cursor region. Moving the cursor beyond the edge of the graph pans the display left (showing older data points) and right (showing more recent data points). Remember, the time window shown in the graph does not change with time. As the data points get older, the data will scroll to the left as new points are taken.

Cursor Display

The cursor readout displays the horizontal position and the trace data at the cursor. The horizontal position is displayed as time (from the beginning of the trace), delay (time from the most recent point), bin (number of data points since the start), and fre- quency (if the reference is internally swept). In this illustration, the cursor point was taken 36 seconds before the most recent point.

Marks

While data is being added to the data buffer, events may be marked using the [MARK] key. Pressing [MARK] will tag the next trace buffer location. A mark will appear on the chart and will scroll with the data. This is analogous to marking a real strip chart while it is recording. Marks are useful for marking when an external event occurred or when the experimental conditions changed.

A maximum of eight marks may be placed in the data buffer. A mark will appear on ALL stored traces at the same buffer location. The different mark symbols are shown below.

A mark is always placed at the buffer start to mark the oldest (first) data point at the start of a scan.

The [EDIT MARK] key allows the mark data to be viewed. The value of each stored trace and the time the mark was placed is displayed. The user can add comments to the mark data to label a spe- cific event.

When trace data is saved to disk, the marks are saved as well. When a trace is recalled from disk, the marks are recalled as well. Existing marks are replaced with the recalled marks.
