Re: OSX Sierra compatibility with 6.11.13.2

Thanks a bunch, up and running now.

Some buggy behaviour though, will give feedback later.

Re: PicoScope calibration

I might add that if possible I would like adjustments to get as accurate performance as possible, not just a measurement check-up.

Re: PicoScope calibration

For service calibration of a Picoscope 4562, are we talking about a return to UK or do you have approved partners around Europe?

Re: OSX Sierra compatibility with 6.11.13.2

I'm on Sierra (10.12.6) and Picolog works like a charm. When I install Picoscope everything seems fine but when I click on the icon in the app folder the only thing that is happening is the Pico icon jumping up and down in the dock but the software does not open up and start. Mac OS reports that Pic...

Re: Performance of Picoscope 4262 does not reach expectation

Thanks Gerry! Sorry for bad wording regarding aliasing and "imaging". I do realize the difference between sampling signals above Nyquist that folds down below Nyquist (aka aliasing) and sampling signals below Nyquist but trying to reproduce them without a lowpass reconstruction filter (aka "brickwal...

Re: Performance of Picoscope 4262 does not reach expectation

Hi! Please see attached files. One FFT to show quality of signal generator (Agilent DSOX-3032) stimuli at 1MHz (=low distortion) and three scope views of three different sines below 5MHz. It seems like what we can see is just what you would see on the output of a poorly filtered DAC giving mirror si...

Re: Performance of Picoscope 4262 does not reach expectation

Regarding performance expectations of 4262, are there any known aliasing problems with this scope? I can not get clean results above approx 1MHz no matter if linear or sin(x)/x interpolation is used. This does not go well with the advertised bandwith of 5MHz. Feeding a clean sine (harmonics/spurious...

Re: PicoScope 6.10.8: Log frequency axis

Hi! I was happy to learn that the latest Picoscope 6 allows for the analog hardware lowpass filter at 200kHz to be used as well as the log axis for frequency in spectrum mode. I was less happy to learn that on two installations on two different machines Pico 6.10.16 gives very sluggish response when...

Re: 4000 series and PicoLog

I would love to be able to use my Picoscope 4262 with Picolog.

I assume I should not hold my breath? :)

Re: PicoScope 6 Beta Release for Mac OSX

Hi I'm on Mac OSX 10.6.8 on my everyday machine and have no plans "downgrading" to a more recent OS. It's not possible to install Mono on the older OS 10.6.8 which means I'm out of luck using Pico on my Mac without re-booting to my bootcamp Windows installation. Will this always be the case or can I...

Re: PicoScope Beta 6.10.2: Log frequency axis

Really great that you got this in place. What I miss though in this Beta is the 200kHz hardware filter setting for 4262. Hope you get that back soon. It's also missing in the latest version. R6.9.14. but is there in R6.6.57. Also it would be nice with better control of Y axis scaling in spectrum mod...

Re: Error reading THD+N

Thanks for reply. This scope seems very nice for general audio work but proper distortion analyzis feels essential. I use to use a high quality pro sound card but also a scope (3224) for analyzis. With 4262 it seems you can get by with one unit only but proper software functions is important. I also...

Re: log-scale?

Hi!

Thanks for reply. It makes sense to have good functions for audio analyzis with this scope.

Re: The AWG issue of PicoScope5204 on PicoScope R6.6.18

I was trying to read up on the performance of the signal generator of 4262 since that built in generator is one of the reasons I'm considering this scope. It's not clear to me what kind of performane to expect since the manual is not very informative in this regard. It says DC-20kHz and sine, square...

Re: log-scale?

Hello I was surprised back when I purchased a 3224 that there was no log option. I'm about to equip a new workstation and looking at a 4262 for audio analysis and I'm even more surprised that this has not been implemented yet six years later. Can you confirm that you will implement this and if so wh...
