Rigol DS1052E- How many FFT points

(1/3) > >>

Flavour Flave:
Actually it is the upgraded DS1102E thanks to you guys  ;D
Anyway, does anyone know how many points the Rigol DS1102E FFT function uses? Because I want to work out the FFT noise floor. Couldn't find it in any of the documentation.
Thanks

Just needed to know because I was reading this Analog Devices tutorial here http://www.analog.com/static/imported-files/tutorials/MT-001.pdf

pfm:
bump.
seeking the same info (number of FFT points) for this Rigol series and can't seem to find it anywhere and found this thread while searching for it. Hoping someone knows and will post here.
Thanks.

Typically, in such simple oscilloscopes the manufacturers just use enough data points to fill the screen. Because of the negative frequencies and the symmetry, this means using twice as many data points (ok, in theory (W - 1)/2) as input to the FFT as the screen is wide.

Probably less if their engineers optimized for bezel thickness, e.g. (<total horizontal pixels> - <horizontal bezel pixels>) buckets...viz. information limit is dictated by screen resolution, so it wouldn't make sense to have more buckets than horizontal pixels...unless the number of buckets is base-2 or coprime factorable.

pfm:
called Rigol, its 600 points. Its kind of eluded to in the "programming guide" as well.
Hope this helps anyone looking for this info.
