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.57 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.57, both Channel1 and Channel2 are chosen as source,
measurements are taken for Frequency, Pk-Pk value, Mean and RMS.
