Purposes
a) Calibrate the Oscilloscope so that it displays the signals correctly (possible using the "Autoset" mode).
View of the 19 automatic measurements
c) Use WinZoom to characterise a rising edge
Whole acquisition, Tm measure
b) Measurement precision (e. g. Rise time) is directly dependent on the vertical resolution of the A/D converter
(12 bits on Scopix, 10 bits on OX 6000 and OX MTX, 8 bits on competitor models) and on the sampling rate
used, which must be optimised in relation to the planned measurement.

no. 7 : Square - Rise time
Type 1 square signal with a 50 % duty cycle
Vpp ≈ 3.4 V - F ≈ 10 kHz - Rise time ≈ 690 ns
500 ns at 200 µs/div. - MAIN = 500 mV/div.
Triggered mode preferred – select "Repetitive signal" (Horizontal menu)
Use of Automatic Measurements (F, P, Rise time, Fall time, Vpp, Vrms, etc)
Notion of measurement precision using rise time test
Use WinZoom to characterise a rising edge
Zoom does not provide more
as the measurement was already made
on the full memory and not the screen
