Procedure calibration
The generator should be calibrated as followed:
[1]Verify the +5 V supply.
[2]During the first test, set all potentiometers and adjustable capacitors to their medium val- ues.
[3]Adjust to the potentiometer 50 ns adj
(3)in order to obtain a 500 ns long pulse on TP2 (2).
[4]Connect an oscilloscope allowing the mea- surement of the signal’s period on the output Trig out.
