The 7904 is a 500MHz mainframe with four bays. It accepts two 7000-series vertical plug-ins and two 7000-series horizontal plug-ins. The performance is largely determined by the plug-ins. The 7904 makes extensive use of custom integrated circuits and hybrid circuits. The signal path is completely differential and all of the internal wiring is 50-ohm coax. The 7904 has a many modes of operation. One mode is called "Independent-Pairs Display" in the manual, where the input to the left vertical plug-in is displayed using the B horizontal timebase plug-in, and the input to the right vertical plug-in is displayed using the A horizontal timebase plug-in. This resembles the trace-slaving "ALT" mode that is produced by a 1A4 in a 547. Many other modes are available. It is possible to put vertical plug-ins in the horizontal slots for X-Y operation. It is even possible to put a horizontal plug-in in one of the vertical slots to produce a raster scan. The CRT has distributed vertical deflection plates. The total acceleration voltage is 24kV.
