Understanding Oscilloscope Functions

TDS1000/2000-Series Digital Oscilloscope User Manual

Cursors

This method allows you to take measurements by moving the

cursors, which always appe ar in pairs, and reading their nume ric

values from the display readouts. There are two types of cursors:

Voltage and Time.

When you use cursors, be sure to set the Source to the waveform on

the display that you want to measure.

To use cursors, push the CURSOR but ton.

Voltage Cursors. Voltage cursors appear as horizontal lines on the

display and measure the vertical parameters.

Time Cursors. Time cursors appear as vertical lines on the display and

measure the horizontal paramete rs.

Automatic

The MEASURE Menu can take up to five automatic measurements.

When you take automatic measurements, the oscilloscope does all

the calculating for you. Because the measurements use the waveform

record points, they are more accurate than the graticule or cursor

measurements.

Automatic measureme nts use readouts to show measurement results.

These readouts are updated pe riodically as the osc illoscope acquires

new data.

For measurement descriptions, refer to page 94 in the Reference

chapter.
