|Tektronix 7B52 Oscilloscope|
|Description||Dual Time Base Plugin|
Introduction The 7B52 Dual Time Base is designed specifically for use with the 7503 Indicator Oscilloscope; however, it is compatible with all 7000-Series Indicator Oscilloscopes. The 7B52 features calibrated sweeps from 5 s/div to 50 ns/div (0.5 s/div to 5 ns/div with X10 Magnification), triggering to 100 MHz, and four display modes. Other features include lighted pushbutton switches, 0 to 10 times continuous sweep delay, bright base line in AUTO mode in absence of adequate triggering signals, and an AMPL position for X-Y operation. Display modes include MAIN SWEEP, INTENSIFIED SWEEP, DELAYED SWEEP, and MIXED SWEEP. In the MIXED mode, the Main Sweep is displayed to a point selected by the DELAY TIME MULT, after which the sweep rate is determined by DLY'D SWEEP setting. This mode permits sweep magnification of any point on the normal (Main) sweep selected by the DELAY TIME MULT control.
