Using cursor readouts
Cursor readouts supply textual and numeric information relating to the current cursor positions.
The instrument shows the readouts when the cursors are turned on. Readouts appear in the upper portion of the graticule attached to the
cursors.
When a bus is selected, the readout shows the decoded bus data in the format you have selected from the choices in the bus menu. When
a digital channel is selected, the cursors show the values of all displayed digital channels.
Note: When serial or parallel buses are selected, the data value at that point is displayed in the cursor readout.
• Δ Readout: Indicates the difference between the cursor positions.
• a Readout: Indicates that the value is controlled by the Multipurpose a knob.
• b Readout: Indicates that the value is controlled by the Multipurpose b knob.
The horizontal cursor lines on the display measure the vertical parameters, typically voltage.
The vertical cursor lines on the display measure horizontal parameters, typically time.
The square and circle shapes in the readout map to the multipurpose knobs when both vertical and horizontal cursors are present.
Using XY Cursors
When the XY Display mode is on, the cursor readouts appear at the right of the display.
The oscilloscope displays rectangular, a, b, and the Δ readouts.
Measurement variables
By knowing how the instrument makes calculations, you may better understand how to use your instrument and how to interpret your
results. The instrument uses a variety of variables in its calculations. These include:
Definition of Base and Top
Base is the value used as the 0% level in measurements such as fall time and rise time.
Top is the value used as the 100% level in measurements such as fall time and rise time. For example, if you set the 10% to 90% rise time,
then the instrument calculates 10% and 90% as percentages of Top and Base, with Top representing 100%.
