Minelab Equinox Challenge

[EL NINO]

Have you tried a lower 'bit depth' ? 16 bits is more than enough, maybe then you can achieve higher sample rates, or longer sample lengths?

Thanks for your help - I set it up to 16bit and it works well ..in max...


But it's still not perfect, -the scanner is within Equinox frequency limits - I'll have to buy a better sound card -192 / 24bit ... Limited range spectrum at 65K FFT and full spektrum at 32k FFT

I just try to measure it, but I'm afraid I'm already in the limit, my laptop has more than 10 years...

Do you have 192kHz sample rate as an option, Nino ?
Do you think it will make any real difference to the spectrum analysis ? At 96k sample/sec, he's (just) sampling more than two samples per cycle of the highest freq of interest, 40kHz.

Hi Skippy... I think the setup can be 96kHz / 24bit limit, because in VA program my good working maximum setting is: 96000 Hz / 32500FFT-mono-24bit ... if i change to 96000 / 65000FFT ... I'm losing the signal from the highest 39kHz frequency..

El Nino, you're sample rate is too low to capture these signals at decent resolution.

Hi ... Carl ... thank you for warning .. something is not quite ok, .... .... my laptop's sound card - it allows sampling up to 96 000 Hz / 24 bit, and in the VA program alone -mam set-up up to 96000 Hz / 32500 FFT-24bit ..so I'll have to buy better an external sound card...or new laptop..

in these new Scan Tests I used the probe as the external ferrite AM antenna-from Tescun pl 365 - I think the measurement results are quite accurate ..,

Ivconic..I tried a snipping tool and that's ok ..

As long term totally dedicated Windows user; still i keep forgetting on it.
Every once in a while i "discover" all over again that nice and neat Windows component.
Crazy.
Because on each new Win installation i also do install SnagIt as my default tool for screen&area grabbing.
But i also do use Snipping Tool too... when i recall that it exist on system!

%windir%\system32\SnippingTool.exe
...
For indeed simple and fast manipulation, cropping, converting between all the possible picture formats; ACDSEE soft. Any version.

You can also use "Alt" and PrtScn to just capture the active window, and miss out your desktop background etc. It may be useful, a bit.
And as mentioned , there's a new thingy called 'snipping' that is included with the newer Windows versions.

with the VA program will not be a problem to do a lot of stuff .., I do not think the FFT would have been inaccurate in this direction, but I try to compare it .. On Screenshots I used Lightshot program ..
