2. users can permanently store 6 waveforms in the oscilloscope memory and rewrite them
at any time.
Reference Waveform
The REF channel is used to display the reference waveform, which can compare the
actual waveforms with the reference waveforms so as to find out the differences.
Press Menu button to enter, and select Ref to enter reference Waveform menu.
REF Menu Table
To save the reference waveform, follow these steps:
1. Press F1 to select the position of the reference waveform.
2. Press F2 to open the REF channel.
3. Press F3 to select the source to CH1 (or CH2), and only select the open channel.
4. Press F4 to save the current waveform to the specified location..
Measurement
Scale measurement
Graticule: This method allows you to make a quick, visual estimate and take a simple
measurement through the graticule divisions and the scale factor.
For example, you can take simple measurements by counting the major and minor
graticule divisions involved and multiplying by the scale factor. If you counted 6 major
vertical graticule divisions between the minimum and maximum values of a waveform and
knew you had a scale factor of 50mV/division, you could easily calculate your
peak-to-peak voltage as follows:
6 divisions x 50mV/division = 300mV.
Cursor measurement
The cursor measurement has two parallel lines on the screen, and move two lines to
measure the time and voltage parameters of the input signal. The result of cursor
measurement will be displayed on the second page of the cursor menu. Before use cursor
