CLIO has been designed to give the user a high degree of precision, while

maintaining ease of use thus ensuring confidence in the measurements taken.

Calibration check plays a key role in all this. Note that, as calibration needs to be

performed under controlled conditions, calibration should be attempted the

least times possible; calibration, on the other side, should be verified as needed

or requested all the times the user wants following instructions given next;

verification, not calibration, of your hardware gives maximum confidence when

taking measurements.

3.7.1 CALIBRATION VALIDATION

To verify the calibration, first check that the generator output level is set to 1V

(refer to chapter 4 for details).

Press the channel A In-Out Loop button

Then click on the MLS&LogChirp button

to invoke the MLS&LogChirp control

panel. Press the Go

button to execute a LogChirp frequency response

measurement; after about 1 second you should obtain the desired result, a

straight line (black) as in Figure. You can click on the graph and inspect the

amplitude of the measured signal: you should obtain a reading around 0dBV, this is

the correct output level of the LogChirp signal with the generator output set to 1V.

Now click on the Sinusoidal button

to invoke the Sinusoidal control panel as in

Figure. Press the Go

button to execute a Sinusoidal frequency response

measurement; after about 3 seconds you should obtain the desired result, again a

straight line (black) as in Figure. You can click on the graph and inspect the

amplitude of the measured signal: you should obtain a reading around 0dBV.
