Look at this 42V/20A max PSU, and at this low THD oscillator.

Hi all,

I have bought from a fine seller a new PSU (42V, 20A max). Look at www.test-measure.co.uk It is all new, perfect working and low cost. No problems with the seller.

He sells also in www.ebay.co.uk (where he is 'snibbo') a very fine working oscillator (the LDO 100) that has THD <0.003% from 20Hz to 20kHz, 80kHz bandwidth.

I have bought both from him at very low cost, and other instruments too, that he is now selling with the greatest satisfaction

I share these informations with all of you as my friends in diy.

Best regards

Hi all,

I have produced some FFT plots of the sine produced by the LDO 100 oscillator at frequencies of 100 Hz, 1 kHz and 10 kHz.

They look good

The load was 600 Ohm. In was at 1Vrms, this is 0 dB on the plot.

Best regards

at 100 Hz :

at 1kHz :

and the last one at 10 kHz :
