The Tektronix 7250 is a digitizing oscilloscope with 6 GHz bandwidth, optimized for digitizing single-shot events. It uses a scan converter CRT for digitizing. From the scan converter, the trace is transferred to memory boards containing conventional RAM.
The input is through a 50 Ω N connector on the rear panel, which loops through, rather than being terminated internally. Like in the 519, there is no vertical amplifier.
The captured waveform can be transferred to a computer via a GPIB interface or can be viewed on the built-in monitor, which is a conventional computer-style CRT display and has menus.
At 60 kg (132 pounds), it is the heaviest one-piece oscilloscope ever sold by Tektronix. It was made by Intertechnique in France where it was sold as the IN7000, and rebranded by Tektronix for sale in the United States.

The 7250 has two 3.6 V ½AA lithium batteries on each memory board. With time, these batteries die, which will cause the 7250 to fail its power-on self test. New replacements are still (2011) widely available.
