This is a 7B53A Dual Time Base Plug-in, compatible with 7000-Series mainframes. This time base will trigger to 100MHz and has normal, intensified delaying, delayed, and mixed sweep modes. Delaying sweep speeds are 50 ns to 5 s/div in 25 steps (calibrated) and at least 2.5 times the calibrated sweep rate, continuously variable between steps (uncalibrated). Other very useful functions are X10 MAG, INT. and EXT. (main delayed) trigger inputs, single sweep, front-panel Cal and fine/coarse position controls. The unit is recommended for use with 7313 and 7600-Mainframes. These units are tested and functioning but may need calibration.

The 7B92A Dual Time Base Plug-Ins provide normal, delayed, intensified, and alternate sweep operation for Tektronix 7000-Series Oscilloscopes. The 7B92A is primarily designed for the high-frequency 7000-Series Oscilloscope systems; however, most 7B92A functions are compatible with all 7000-Series Oscilloscopes. They will function more slowly with the lower frequency units.

Additional features include lighted push button switches, compatibility with indicator oscilloscopes having an alphanumeric readout system, and 0 to 9.8 times continuous sweep delay. A variable control allows continuously variable sweep rates between calibrated steps. Also, when operating in the auto main triggering mode a bright base line is displayed in the absence of a trigger signal. This unit is in good used condition but may require calibration before use.
