CSV can be used to export digital channels, analog channels, or a mix of digital and analog channels. Different options are available for each of these cases, and the format varies slightly. For instance, when exporting just digital channels with CSV and in one row per change mode, there will only be one set of timestamps in the file. When exporting digital and analog data, one row per change mode is the only format for the digital component, but timestamps are created for each channel individually instead of being shared between all digital channels. This special "mixed mode" export feature is not available unless at least one analog channel is present in the export. The only way to accomplish this for digital-only exports is to export each channel, one at a time, to separate files.
