Taking Measurements

TDS 300 Series oscilloscopes have two features that make it easy for you to

measure data from a displayed waveform: automated measurements and cursors.

Automated Measurements

The oscilloscope can perform 21 different automated measurements on a

waveform (four measurements at any one time). To access these measurements,

press the MEASURE button, shown in Figure 3–12.

Figure 3–12: The MEASURE button

The MEASURE button activates the measure menu, shown in Figure 3–13.
