Exactly. One thing, the short sequence has the low energy needed for more accurate analysis, the second thing, the resistance to space. This is especially true for low frequencies.
In another measurement system, I use a much longer sequence and aven averages, and I can measure even one meter. Stepped Sine, of course, is the ideal one, but if Farina's method follows certain rules, the result is very good.

CLIO Pocket
Hello everyone:

Sorry I've been out of the loop around here for a while. Got busy. :)

General notes on CLIO Pocket 2:

1. Minor upgrades with changes to the numerals to the right of the decimal are free, such as v1.1 to v1.5.

2. Major upgrades with changes to the numerals to the left of the decimal are not free, such as v1.x to v2.x.

3. The cost of the upgrade to CLIO Pocket 2 from version 1 is €50.

4. We do in fact charge extra for breathing while making measurements if you are grumpy. :)

5. Other than general stability improvements, these are the main feature adds to version 2:

a) The Farina method in the Log Chirp module to draw THD, 2nd and 3rd harmonics. 2nd and 3rd harmonics make up the vast majority of loudspeaker distortion. Higher harmonics are not as useful. CLIO Pocket does use the first (7) harmonics to calculate the THD plot. Since the THD is the "total" sum of harmonics, if you see the 2nd harmonic tracking closely to THD (for example), you know that most of the DUT's distortion comes from the 2nd harmonic. If both 2nd and 3rd harmonic plots are significantly lower than the THD plot, you know that most of the distortion comes from harmonics 4th and higher. I've never seen that, but it's an illustration that helps you understand what's going on.

Since the Farina method only looks at the harmonics when calculating distortion, THD, 2nd and 3rd harmonics do not include the noise component of the measurement. Thus THD is total harmonic distortion, not THD+N (noise).

b) Percentage tolerances relative to a reference resistor, capacitor or inductor. This helps sorting through a quantity of components and placing those within a given percent in the same bin for future use.

c) File save in Excel format is new if you're into that.

Always give a quick look at THD when you make measurements. It's extremely revealing.

Finally, here’s the fine detail on version 2’s upgrades from the new manual:

*- Second harmonic, Third harmonic and THD response
*- Save Impulse time data to wav file
*- Export ASCII or Excel data to file or clipboard
*- Dedicated Hot Keys to facilitate measurement inspection
*- AutoSave function with automatic file name generation
*- Filter: C-Weight
*- THD reading: % and dB (in the FFT module)
*- Frequency reading with 0.1Hz resolution
*- LCR % readings for easy components selection
*- Color map 3D & 2D display
*- Selectable color map shading
*- Powerful 3D marker inspection
*- Wavelet Cycle Decay for detailed decay analysis
*- Fully configurable frequency, time, cycle and amplitude axis
*- Circular Polar Plots
*- Half polar display
*- Analyzes Log Chirp frequency response
*- Frequency smoothing
*- Possibility of mirroring data of symmetrical speakers
*- Up to nine simultaneous plots at specified frequencies

I am happy to see that the pocket now includes 2 and 3 and total harmonic dist plots but i do not understand the display setting option, is it only possible to show one curve at a time and not in any user combination?

THD curves visible now. Remark though, would have been nicer if the THD selection would be fixed (same way as the timing settings, when selecting the phase or groupdelay every measurement keeps on displaying that curve. At this moment the SPL curve appears with every measurement and you have to go to the menu to select the THD again.
What I now find out, you must not use the menu
You can change the view by pressing :
1 - SPL
2 - THD
3 - 2nd harmonic
4 - 3rd harmonic

It's a little bit ugly that Audiomatica does not mentioned this in the manual ...

I think I have all the updates available, v1.51 was probably not distributed.
The version v2.0 seems now to be sold with the hardware at 649 €.
The price of the hardware with 1.x versions was about 600 €
You can get the 2.0 update directly from Audiomatica, it costs about 50 €, if I remember correctly.
