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. ***MPN 7B53A ***OEM Tektronix, Inc (TEK) ***SKU*** J01188
