9. Set Skin
Press the “skin” option button or turn the “Universal” knob to select “Classical”, “Modern”, “Traditional”
or “Succinct”.
a) X-Y Format
Use the XY format to analyze phase differences, such as those represented by Lissajous patterns. The
format plots the voltage on channel 1 against the voltage on channel 2, where channel 1 is the horizontal
axis and channel 2 is the vertical axis. The oscilloscope uses the untriggered Sample acquisition mode and
displays data as dots.
XY mode has a breakthrough that traditional oscilloscopes restrict sampling rate at 1MSa/s, support
25KSa/s ~250MSa/s (1-2.5-5 sequence) adjusted.
Operation steps
●Channel 1 “Volt/div” and vertical “POSITION” set up the horizontal scale and position.
●Channel 2 “Volt/div” and vertical “POSITION” set up the horizontal scale and position.
●Turn the “S/div” knob to adjust the sampling rate
●The following functions are forbidden at XY display form:
●Benchmark wave form and wave mathematic
●Cursor
●Auto (resets display format to YT)
●Trigger Control
●Horizontal Position Knob
●Vector Display Type
●Scan Display
K) Measure System
The Oscilloscope displays the voltage in relation to time and test the wave form displayed. There are scale,
Cursor and auto measure modes.
a) Scale Measurement
This method allows you to make a quick, visual estimate. For example, you might look at waveform
amplitude and determine that it is a little more than 100 mV. You can take simple measurements by counting
the major and minor graticule divisions involved and multiplying by the scale factor. For example, if you
counted five major vertical graticule divisions between the minimum and maximum values of a waveform
and knew you had a scale factor of 100mV/div, then you could easily calculate your peak-to-peak voltage as
follows:
5 divisions x 100 mV/division = 500 mV.
b) Cursor Measurement
Figure on next page displays the cursor button on the front-panel for this menu.
