7250
The Tektronix 7250 is an digitizing oscilloscope with a 6GHz bandwidth. It uses a scan converter CRT for digitizing. From the scan converter, the trace is transferred to memory boards conventional RAM. The vertical resolution is 11 bits. The digitizer captures 512 samples in one shot. The fastest sweep is 50ps/division, approximately 1 terasample per second. The sensitivity is 500mV/division. Due to the absence of vertical amplifiers in the signal path, the 7250 can handle 2kV spikes without damage. The input is through a 50-ohm N connector on the rear panel, which loops through, rather than being terminated internally. At 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.
Frequency response of a 7250 has been measured as -3db@7GHz, -6dB@9.6GHz, and -8.5dB@14GHz. (Haas, Warman, van Ewijk, Rev. Sci. Instrum. 60 (3), March 1989)
