The rapid changes which are taking place in electronics today are causing engineers, designers, technicians and instructors to take a critical look at the equipment they will need to keep pace with these changes. The dramatic increase of solid state components being used has created different test equipment requirements than the tube circuits of the past. The increasing use of Field Effect Transistors and Integrated Circuits are other important facts to consider. What do all these changes mean to the area of oscilloscopes? First, the lower potentials used in these circuits and the much lower signal levels call for an instrument with increased sensitivity if it is to be practical for the design and servicing of solid state circuits. More emphasis is being placed on critical waveform analysis and the comparison of waveforms, particularly the timing of “concurrent” waveforms present in much of the equipment used today. This includes the fields of television, computors, and particularly the educational field. The instrument to fill these applications requires triggered operation for the meaningful measurement of pulse time and concurrent waveform comparison. It must have full dual trace capability if any comparisons are to be made. In addition, it must be simple to operate and provide full versatility. The PS163 fulfills these requirements and more. Ease of operation has been one of the important design considerations of the PS163. The Free Running sweep feature has been added to simplify operation for those not familiar with triggered sweep scopes. The PS163 incorporates the latest in solid state design to assure long and trouble free service. A glance at other features of this practical instrument will point out its many uses and advantages. FEATURES *** EXTREMELY STABLE triggered sweep with full bandwidth capability in both automatic and manual triggered modes, PLUS free running capability for use as a sync-sweep service oscilloscope. *** COMPLETE DUAL TRACE capability with pushbutton selection of CHANNEL A, CHANNEL B, DUAL ALTERNATE or DUAL CHOPPED displays, PLUS Sencore’s exclusive VECTOR mode for direct display of phase relationships. *** VERTICAL INPUT SENSITIVITY of 5mV/cm direct. 50mV/cm with low capacity probe. Input attenuator calibrated to read directly when using low capacity probe. Gain continuously variable between attenuator positions. *** BANDWIDTH of DC to 8MHz-3db, useable to 15MHz. Negligible overshoot, typically 1% or less. *** CALIBRATED TIME BASE rates from .1 microsecond to .1 second per division in 19 positions plus TVV, TVH, 60Hz and EXT. positions. Sync separator automatically added in TVV and TVH sweep positions for rock solid display of complex TV waveforms. 60Hz and EXT. positions provided for line sweep and use with sweep generators. *** FRONT PANEL correlation between sweep speed and frequency for ease of operation. Sweep speed continuously variable between steps. 5X magnification provided. *** PUSHBUTTON SELECTION of trigger sources: Internal Channel A, Internal Channel B, Line or External. *** HIGH INPUT IMPEDANCE Qf 10 megohm shunted by l l p f using low capacity probe. 1 megohm shunted by 35pf at input terminals. *** FULLY PROTECTED Field Effect Transistor input. Maximum input voltage with the Low Capacity Probe is 5000 volts peak to peak AC, or 1000 volts DC. This allows measurements of signals that can destroy other oscilloscopes. *** ILLUMINATED full size 10 x 10cm grid PLUS illuminated vector grid at the flip of a switch. No separate grids to change or become misplaced. *** RETRACTABLE TIP on special 5KV low capacity probe for ease of connection in hard to reach places. *** SOLID STATE for dependable accuracy and reliability. 2KV regulated CRT supply wi
