one important parameter now clear is the sweep time that is shown in the

sinusoidal menu status bar: with these settings we have 1.05 seconds sweep time.

Consider it fine. Save the result to “response.sin” file.

The test should now be tuned up to take into account the acoustic environment and

completed with missing settings. Open the sinusoidal settings dialog; proper delay

should be set to compensate for microphone distance to loudspeaker, this may be

evaluated by the two common ways CLIO gives you i.e. taking a trial sinusoidal

measurement with auto delay active or taking a parallel MLS&LogChirp

measurement and inspecting the impulse response; in our case we found a 0.2ms

delay to be compensated, due to a quasi near field measurement with a

microphone to DUT distance, in the acoustic fixture, of circa 7cm. Final settings you

may require are about distortion curves; we may activate THD calculations clicking

on “THD Enabled”, the Rise parameter is set to 0dB as we are going to

accommodate all displayed curves inside one single 100dB Y scale graph. Execute

the measurement with final frequency response settings.

After the measurement is done we may inspect THD and 10th harmonic pressing

the THD button and selecting the proper harmonic with the drop-down, in figure

they are shown as overlays (green THD, orange 10th harmonic). Repeat the

measurement until fully confident with the results obtained, eventually refine the

settings as needed.

11.3.2 SETTING UP THE IMPEDANCE RESPONSE

We put now our attention to the impedance response of our loudspeaker.

We choose CHB with the input channel selector and Ohm as Y Scale unit; inside the

sinusoidal settings dialog leave all previous settings unchanged as they will

accompany us to the final reference measurement; only change the impedance

settings to “QCBox Select” to reflect QCBox operation.

As the output level has already been set for the acoustic test we only have to deal

with input sensitivity for channel B; a settings of -30dBV or -40dBV is usually

correct for ISense impedance tests. The measurement looks as follow.
