<div><font face="Arial" size="2">is of the LT2208 being clocked at
100MHz from a low noise crystal oscillator. The FFT shows the spectrum
from 0 - 50MHz using 4096 FFT bins and a Hann windowing function. The
signal input is at 25MHz from my HP8640B signal generator at +10dBm.
The input amplifier in the LT2208 is set for maximum gain which gives
an input overload of 1.5v and a noise floor of -86dBm in the above
FFT bandwidth. </font></div>

FYI -- This ends up pointing to a JPEG file named LT2208, but lacking
the .jpg
extension. Declaring it as a JPEG makes it fetch just fine.<br>

Most impressive, Phil. Was this with the 14 or 16 bit LT2208?<br>
