Purposes
a) Calibrate the Oscilloscope so it displays the signals correctly (possible using the "Autoset" mode).
Normal Oscilloscope mode
Due to its extremely high acquisition rate compared to a conventional Digital Oscilloscope (up to 50,000 per
second instead of around 10 per second) and to its intelligent display algorithm, the SPO Oscilloscope enables
visualisation of rapidly varying signals or complex composite signals, as possible on an analogue Oscilloscope.
For the signal generated we can characterise a zone of amplitude that has never been reached and the
temporal distribution of the signal with colour shading.
b)
c) On our Oscilloscopes, it is possible to rapidly create a reference for comparison with a new acquisition (see
test no. 3, final part).

no. 6 : AM Modulation sine
Type 1 sinusoidal signal with amplitude modulation
1.3 V < Vpp < 3.3 V - F ≈ 1.3 kHz
100 µs/div. - MAIN = 500 mV/div.
Triggered mode preferred, SPO duration mode 100 ms
Visualise a signal with rapid variations (e.g. modulation) using SPO
Use of the "Envelope" mode on OX 6000 & Scopix
Automatic Measurement of variation from reference
Multi-colour SPO mode
On the OX 6000 and Scopix
models the Envelope and
Cumulate (OX 6000-II &
SCOPIX) modes enable
rough visualisation of the
signal (max Vpp, modulation
rate, frequency, etc.).
In the "Automatic Measurements" panel, a check box lets you display
the difference between the current acquisition and the memorised
reference (e.g. dVpp = difference in Vpp value).
