Grey Scaling
and PersistenceWith an analog display, faster signals appear fainter than slower signals. Called grey scaling, this phenomenon gives important clues about relative frequencies when analyzing mixes or overlayed signals like video waveforms.
Or when an event only occurs
occasionally in a repetitive signal, the anomaly will fade quicker and look dimmer than the rest of the waveform. This persistence effect reveals critical information when analyzing and debugging complex analog designs, such as switching power supplies.The 2467B includes all the functionality of the venerable 2465B including:
Additionally the 2467B adds the Bright Microchannel Plate Display (MCP) which can increase the intensity of a dim waveform (due to gray scaling and persistence) up to 1000 times.
