It would be nice if I could elect a log scale for the Y axis on analog traces. Other functions might be nice as well.
The limited input voltage range on the Saleae is forcing me to create off-board attenuation network for signals greater than 10V. It would be very nice to apply a correction factor to the Y scale on the analog waveform so that the levels are displayed correctly on graph.
Newer hardware should also be able to handle higher voltages. For example the Tech Tools DV-509 9 channel / 500Msps unit ($479) can handle +/- 20 volts.
Although the automatic vertical scaling is nice, sometimes you need a fixed scale. This allows you to visually compare traces and not have to read off voltages. Combine this in the dialog box to select Log!
It would be better if I could select the best scale fit to my needs (min, max) for the Y axis on analog traces.
Jim - Referring to your own comment upon:
one could achieve this by taking the log of the Y-value!
(OK, I grant you having a simple UI option to set a log scale would be easier.)
