7) The white and pink noise amplitude accuracy is verified at a single amplitude level using the
DVM. Note that noise signals, especially the pink noise, will vary and require a very long
integration time for stable measurements. Set the DVM to analog (non synchronous, no external
sync) with an integration time of over 10 seconds.
