Informationen

Cathode Ray Oscilloscopes have one basic advantage over any other measuring and indicating instrument, and that is the ability to plot a practically instantaneous visual curve of one variable as a function of another. The electron beam of the cathode ray tube provides an indestructible pointer of negligible inertia that practically no limitations exist on movement in either horizontal or vertical plane. Thus, practically any measurement, static or dynamic, whether it is chemical, mechanical, thermodynamic that can produce an electrical impulse, can be made on a Cathode Ray Oscilloscope. The Industrial and Television POCKETSCOPE stands out particularly among Cathode Ray Oscilloscopes, due to many features that make it so complete. * Identical horizontal and vertical amplifiers for measurement of AC and DC, with sensitivity better than 100 mv. rms/inch from 0 cycles to 200 KC and with fidelity of response to within —2DB; single-ended input with push-pull output; the same polarity of deflection through the amplifiers as with direct connection to deflecting plates; M megohm input resistance and 35 mmfd input shunt capacitances at low inputs; 10 megohm input resistance and 10 mmfd input shunt capacitance at high inputs; trace expansion of at least twice screen face without distortion; unusual stability of amplifiers with line voltage variations; variations of input impedances, or manipulation of controls do not bounce the trace of the screen and the trace returns instantly to original position. * Direct connection to deflecting plates either single-ended or push-pull for either AC or DC measurements with sensitivity of 28 volts rms/inch and fidelity only limited by external connec- . .tions. as shunt capacitance is only 10 mmfd from each plate to ground and input resistance is 10 megohms from each plate to B+. * Linear time base Oscillator using hard tube, and with range from 3 cycles to 50 KC with blanking of the return trace is optional. * Intensity modulation Amplifier with sensitivity of better than 100 mv/rms per inch for threshold blanking below 500 KC. For direct connections, 1 volt rms is required. * Synchronization of the sweep either internal vertical, external or line frequency is provided with positive polarity of sync. * Centering range is at least twice screen face and is operative whether the connection is through the amplifiers or directly to deflecting plates. * Input may be isolated from the case, at will, so that low side may be connected to the hot DC wise, terminals. * Weight is only 8% lbs., Height 7", Width 5", Depth 11". A functional layout of controls permits ease of operations. A leather handle, retractable light shield, detachable graph screen, outside fuse protection, and mounting feet on bottom and back, contribute a great deal towards convenience of operation.
