How to Implement the Automatic Measurement
This is where users would come across every time they use our scopes. It is take
the measurements by using oscilloscope. Our oscilloscope does this automatic
every time user press Measure button. It is capable to work out 20 different
types of measurements, and there are 4 measurements can be displayed on the
screen at one time.
The 20 types automatic measurements include frequency, cycle, average value,
peak-to-peak value , root mean square value, Vmax, Vmin, Vtop, Vbase, Vamp,
Overshoot, Preshoot, RiseTime, Fall Time, +Width, -Width, +Duty, -Duty,
DelayA B and DelayA B .
To use Measure, simply Press Measure button would activate MEASURE menu.
Press F1 next to Source/Type to allow you to switch between Source and Type.
Source is the signal from the channel which user to carry out a measurement,
and Type is one of the 20 measurements user wants Oscilloscope to work out.
Under the Type as you can see in Fig.
63
is what the actual measurement
reading is. The reading would show sign of "?" if there isn't a measurement can
be worked out from the source signal. As in Fig.
63
, both Channel1 and Channel2
are chosen as source, measurements are taken for Frequency, Pk-Pk value, Mean
and RMS.
