4.10 CURSORS FUNCTIONS

CURSORS
TRACK
The analog mode of the oscilloscope is often used to accurately display complex
waveforms, such as in AM, FM, and Video.
The digital mode will often be the preferred operating mode for single accuracies
which have to be studied or analyzed.
When operating in digital mode, the cursors are always set to the optimum place
for that particular measurement and the readout is directly displayed on the
screen.
This is the fastest and easiest way for most of the measurements .
But for measurements on very complex signals with different waveforms in a
trace, the analog cursor measurements gives you a very helpful tool to find your
measurement.
STANDARD SETTING
Start with the standard setting. This ensures you have the correct start condition.
- Press the STATUS and TEXT OFF keys simultaneously.
- Connect the Probe Adjust signal to channel 1.
The Probe Adjust signal now supplied to the input is a square wave with a lower
level of 0V and a top level of 600 mV.
- Press the AUTOSET key.
Cursors are provided to make fast and accurate amplitude
and time measurements. These can be done in digital
mode as well as in analog mode.
