Tektronix 7904 Oscilloscope
The Tektronix 7904 is a 500 MHz, non-storage 7000-series oscilloscope mainframe with four bays. It accepts two 7000-series vertical plug-ins and two 7000-series horizontal plug-ins. There is also a rack-mount version, the R7903, albeit with only one horizontal bay.
The 7904 was introduced in late 1971/early 1972 (Note 1). In 1984, it was replaced by the redesigned 7904A.
Performance is largely determined by the plug-ins. The 7A19 vertical amplifier and 7B92 time base were introduced along with the 7904 to match the 500 MHz system bandwidth
