The test setup data for each tube, including the voltage settings and the expected emission current and transconductance, is stored in an on-board EEPROM device. This memory device retains its memory with power off, so tubes can be tested without connecting the unit to a computer. Tube test settings can be modified using a personal computer, or new tubes added, and the resulting data file uploaded to the AT1000. The same data file is used by the TubeTest© software to set test defaults. Here is a list of the tubes currently pre-loaded:
