    In the Microwave Calibration Services Section of the NBS Radio Standards Laboratory, Boulder, Colo., and analysis of calibration data obtained from measurements made on a rotary-vane type attenuator reveals that the vane alignment produces an inherent vane-angle error. It is found that the standard deviation of the measured values of attenuation is correlated with the vane-angle error. Approximate... View full abstract»

    The extremely fast ionization process in semiconductors offers a means of generating pulses that have subnanosecond rise times and high peak powers. There are several important applications of these pulses which require the duration of the generated pulse to be variable. This report investigates three methods of producing variable-width pulses using transistors operating in the avalanche mode. The... View full abstract»

  • The Crystal-Video Radiometer

    A theoretical analysis is made of a microwave radiometer which utilizes no predetection amplification. The minimum detectable temperature, defined as the temperature which results in an output signal-to-noise ratio of unity, is shown to be (π/BM) (T0/2Kτ0)1/2 where B is the predetection bandwidth, M is the crystal figure of merit, T0 is the ambient temperature, K is Boltzmann's con...

  • The Detection Statistics of a Molecular-Beam Frequency Standard

    The detection statistics of a molecular beam are analyzed, taking into account fluctuations in emission, transition and detection. It is discovered that the over-all process has a Poisson distribution. Because of the nature of this distribution, it is noted that the optimum method of estimating the average number of molecular transitions is by means of a long-time average of the detected current. ...

    The piezoresistive effect, the change in resistivity caused by mechanical stress, is large enough in semiconductors for use in strain gages and other transducer elements. This paper reviews the piezoresistive effect in semiconductors having diamond or zincblende crystal structures and discusses applications. Definitions and typical values are given for the important material properties such as str... View full abstract»

  • Inductive Voltage Dividers with Calculable Relative Corrections

    Inductive voltage dividers are now used in measurement laboratories for the production of audio-frequency voltage ratios with errors (deviations from turns ratio) of a few parts in ten million of input. A major component of error arises from the interaction between distributed shunt impedances and leakage impedances in the windings. Correction for this systematic error in dividers of special desig... View full abstract»

    This paper describes some developed equipment found very useful in evaluating circuits that require digital inputs. For example, D-A converters are generally tested by using their associated A-D converter as a test-signal source. Since the A-D converter itself introduces errors, the measurement of analog input and output indicates over-all performance but not individual converter performance. The ... View full abstract»

    In order to monitor the electron temperature during plasma afterglow experiments, a gated microwave radiometer has been developed. The radiometer differs from the usual Dicke type of radiometer in the input switching scheme and in the fact that a good time resolution is required. The radiometer to be described has a time resolution of one microsecond and a temperature sensitivity of about ten degr... View full abstract»
