Test signal
n°1 : Miscellaneous
Nature
4 pairs of successive signals approx. every 2 seconds.
Specs
2.6 V < Vpp < 3.2 V - 10 Hz < F < 60 Hz
Oscilloscope Settings
50 ms/div. - MAIN = CH1 = 1 V/div. - AUX = CH2 = 1 V/div.
Trigger
standard on CH1 = MAIN
Modes
XY (Display menu)
Objective
Start in a playful manner by describing the different display modes:
Normal, Delayed, XY
a) Adjust the oscilloscope so as to display the signals correctly (possible using the «Autoset» key).
When Autoset is exited, the oscilloscope adjusts the vertical position so that the traces are not superposed.
b) Apply the “Delayed” and “ON” “OFF” commands in succession to be able to observe a complete trace and zoom on detail.
c) Select the «XY mode» with CH1 on X and CH2 on Y. Observe that there is a succession of 4 geometrical shapes.
The geometrical shape obtained in XY depends on the sampling rate, which in our example is Fsample = 50 kHz.
