Application scheme of Puyuan ds1000z series digital oscilloscope in communication principle experiment

Puyuan DS1000Z Series of high cost performance four channel digital oscilloscopes replace the previous two channel oscilloscopes to complete 《 Communication principle experiment 》 Teaching content in the course , Make the test project more comprehensive , The experimental process is simpler , And it helps to clarify the experimental principle intuitively , Improve students' practical ability .

Test requirements

Modulation and demodulation is a very important communication technology , By using measuring instruments （ Such as oscilloscope ） Observe various signal waveforms output by the modulation and demodulation circuit （ Include ： carrier , Modulation wave , Modulated wave , Demodulated waveform ） And make necessary measurements , Students can intuitively master the principle of modulation and demodulation . Puyuan DS1000Z Series four channels can well meet such test requirements , As shown in the figure below , The oscilloscope can observe the carrier wave on the same screen , Modulation wave , Modulated wave , And the demodulated waveform .

Test plan

Automatic measurement —— special

DS1000Z Provide 24 An automatic measurement parameter , All parameters can be called out with one key through the special measurement menu key on the left side of the panel .

Automatic measurement —— Parameters

Each measurement parameter has a parameter schematic icon , Display what parameters of the waveform are measured by each measurement item , And the color of the icon will be automatically adjusted according to the selection of the measurement source , Let students understand the meaning of measurement parameters more intuitively .

Automatic measurement —— Automatically

The automatic cursor will mark the position of the waveform parameter corresponding to the currently selected measurement item , Visualization helps students understand the measurement results

AUTO Key lock
