what sort of accuracy can this measure to?

dhaen · 24th March 2004, 05:28 PM

Minimum distortion range is -60dB (0.1%). This range has calibration down to -20dB, so the smallest measurement is -80dB (0.01%).
Of course accuracy of measurement will depend upon a low distortion generator and calibration error.

Is this low enough to be useful?

Cheers,

Probably, it would be my first "proper" bit of design and test kit, so I'm sure this would be a good starting place to build from. As, hopefully, over the summer holiday when I'm working I will get a chance to add a few more peices to my collection and actualy get myself set up to test the things I'm building (and hopefuly designing a bit more by then).

and thanks for bidding

Oh, well I guess hits might have been a little expensive as a first peice, but nevermind i guess I can always start somewhere else.

In the end, it went for more than I expected.
Last minute bidders waiting in the wings...
