    This paper gives an analysis of a modified Pierce oscillator for frequency variation due to changes in the circuit or transistor. The magnitudes of the frequency shifts due to parameter changes are computed in relation to each other. The analysis has been verified by testing the oscillator circuit with several transistors which had significantly different measured parameters. Computed frequency sh... View full abstract»

    An apparatus is described which uses the unique properties of an H-plane microwave junction to observe electron spin resonance in a manner analogous to the Bloch induction method. The theoretical sensitivity of this technique is expressed as a function of the parameters of the junction and the minimum observable number of unpaired electron spins. This method is compared with cavity techniques and ... View full abstract»

    A simple semiautomatic instrument for tracing common-emitter hybrid collector and base characteristics of low-level transistors is described. DC supplies, including a transistorized automatic and continuously varying voltage supply, are encountered in the network which allows appropriate biasing of transistors to be tested. Plotting of transistor curves is provided by a conventional X-Y recorder. ... View full abstract»

    The bridgewire of an electroexplosive device is evaluated for its thermal response to impulse energy and to square-wave power. Thermal time constant and basic electrothermal parameters can be measured from the response. These parameters are useful in the study and characterization of electroexplosive devices.

    This paper describes a magnetic angle-encoder development utilizing two microminiature Hall-effect probes and a single-track magnetic drum. This approach to angle encoding and measurement offers possibilities for developing compact and higher-resolution angle encoders for inertial guidance and space platform applications. The Hall-effect probes allow measurement of the magnetic drum's recorded fie... View full abstract»

    A signal-to-noise analysis is made of the Wheatstone bridge, where the unknown and standard resistors may be at different temperatures, a situation which occurs in resistance thermometry. The limiting condition is assumed to be dissipation in the unknown resistor. It is shown that the ratio arms should be low in resistance compared with the unknown resistor, while the standard resistor should be h... View full abstract»

    A bolometric method of calibrating low-level microwave power measuring devices is currently employed at the National Bureau of Standards in Boulder, Colo. The technique is one of direct comparison between the standard and the unknown, and utilizes NBS working standard bolometer units and self-balancing dc bridges. In general, the unknown is calibrated to an accuracy of one per cent. The following ... View full abstract»

  • Bridge Circuit for Measuring Differences of Current or Voltage from a Preselected Value

    Publication Year: 1963, Page(s):34 - 40
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (865 KB)

    A bridge circuit has been developed, using a Zener diode, which enables measurement of small changes in current or voltage from a preselected value. The circuit features increased sensitivity over a meter whose range includes the total current and is more easily used than a balanced bridge or potentiometer. The design equations are developed and the design procedure outlined for both the current a... View full abstract»

    Determination of induced surface current on cylindrical reflectors in a parallel-plate region from measurements of electricfields distribution is described. The probe-reflector interaction in the measurement of electric-fields distribution is examined and the requirement of probe reflector spacing which ensure the small interaction is also investigated.
