To use the automatic measurements you first need to obtain a stable display of
the waveform to be measured. (Pressing AUTOSET may help.) Once you have a
stable display, perform the following steps (see Figure 3–60):
1. TDS 600B: Press MEASURE ➞ Select Measrmnt (main).
2. TDS 500D and TDS 700D: Press MEASURE ➞ Measure (pop-up) ➞
Select Measrmnt (main).
3. Select a measurement from the side menu. Note the following rules for
taking automatic measurements:
You can only take a maximum of four measurements at a time. To add a
fifth, you must remove one or more of the existing measurements.
To vary the source for measurements, simply select the other channel and
then choose the measurements you want.
Be careful when taking automatic measurements on noisy signals. You might
measure the frequency of the noise and not the desired waveform. Your
oscilloscope helps identify such situations by displaying a low signal
amplitude or low resolution warning message.
