3458A DCV Aperture

Am I correct in assuming that aperture time does not actually equal measurement time? I'm asking because I cannot measure the peak value of a 10us pulse even with with an aperture of 500ns. DSDC mode works fine, but I lose the auto ranging which is a nice feature of DCV mode. I've exhausted all of the options in the manual regarding digitizing with DCV mode, but can't seem to find a way to measure a peak value on anythign less than a 25us long pulse. And even then I have to delay the measurement 20us into the pulse to get a correct reading. It almost seems as if there is a ~40kHz low pass on my signal. If anyone has any ideas I would love to hear them.

Thanks!
