2. E EE d Md MM Aaaa YY EE 5810 Introduction This section of the manual contains an electrical descrip tion of the circuits in the 55 1071 Time Base Amplifier plug in unit An overall block diagram and complete schematic diagrams are given on pullout pages at the rear of the manual BLOCK DIAGRAM DESCRIPTION The input Switching permits the sweep triggering signal to be selected from any one of four sources It also provides a choice of AC or DC coupling of triggering and display signals to the Trigger Preamplifier System The Trigger Pre amplifier serves two purposes it provides current drive to initiate a trigger in the Sweep Logic portion of the Sweep Generator and it provides a high impedance input for the external signal Amplifier The Sweep Generator circuit produces a sawtooth volt age which is amplified in the display unit to provide sweep deflection on the CRT Positive and negative going gates are produced at the same time the sawtooth 15 being produced to perform sweep related functions such as CRT sweep retrace blanking etc The Sweep Generator can be operated in any one of several modes including the normal triggered mode the auto triggered bright baseline mode or the single sweep mode The Amplifier allows an externally applied signal to be displayed instead o
