The Tektronix 7104 is a 1 GHz, non-storage 7000-series oscilloscope mainframe that takes two 7000-series vertical plug-ins and two 7000-series horizontal plug-ins. It was introduced in 1978. There is also a rack-mount version, the R7103, albeit with only one horizontal bay.

The scope employs a micro-channel plate CRT design to get good screen intensity at high sweep speeds with moderate acceleration voltage.

The 7A29 1 GHz vertical amplifier and the 7B15/7B10 time base pair were introduced along with the 7104 to match the system bandwidth.

Option 2 adds a horizontal delay line for extended-frequency X-Y operation.
