Again a digital version of an analog function has no additional inherent
value over analog but it could. An example here would be a low and peak
temporary hold display. Normal would be green, max would be red and blue
min signal colors. The red and blue would last a second or two so the
green level indication could respond quickly to enhance the display.
I like the SDR-1000's digital meter (in dBm), as the averaging function
(rate) can be adjusted to the user's liking, or turned off. The peak hold
and normal display colors (in gradient color hues) can be changed, too, for
best visibility. There is also a really cool "analog" representation of an
s-meter as an option, that displays in true s-units and incorporates the
peak hold feature. The "needle" changes color briefly at the peak reading.
It's a high-resolution and realistic representation of an S-meter, and
floats in a separate window so you can place it on the Windows desktop
wherever you like. Finally, because the SDR-1000 is user-calibrated with a
Elecraft XG-1 or other signal meter, the digital meter and the "analog"
s-meter are highly accurate across their range. My SDR-1000 blog entry from
April 13th shows this S-meter in its prior form, before it was changed to a
"floating" window.
