The 7904 had an elaborate 5-decade built-in calibrator with variable rate that was dropped from the 7904A. In the 7904A, The Control Illumination switch moved to the rear panel, and the readout system gained a pulsed mode in which it is synchronized with the sweep instead of interrupting the display at random times. This pulsed mode is not compatible with all time base plug-ins (see manual p. 1-12). | The 7904 had an elaborate 5-decade built-in calibrator with variable rate that was dropped from the 7904A.
