      Masers were used as a type of Parametric Amplifier before low noise solid state devices. In normal amplification the agent (the physical element of amplification using direct local power) has a noise resistance factor that fixed by the random movement of atomic particles (or holes) in . In this paper we report the realization of a CPT Rb maser clock. This study is devoted to test the stability performances of this new clock, having in mind the requirements of the Galileo.

    A maser (/ ˈ m eɪ z ər /, an acronym for microwave amplification by stimulated emission of radiation) is a device that produces coherent electromagnetic waves through amplification by stimulated first maser was built by Charles H. Townes, James P. Gordon, and Herbert J. Zeiger at Columbia University in Townes, Nikolay Basov and Alexander Prokhorov were awarded the   In a signal generator there are 2 things I look for. Realize I do repair not design. I want frequency accuracy and stability with a calibrated output. The ones mentioned have none of those. The B is loved for it's spectral purity but it's old and not user friendly (at least to me, I've had several).

shows the basic design of an analog RF signal generator. A signal generator consists of. As part of a vintage radio restoration project, I decided to build a simple signal generator for alignment. The idea was straightforward, a short distance AM transmitter with a variable carrier frequency in the MW band (at least kHz to MHz) modulated by a fixed low frequency audio tone (2kHz).

If this is a generator intended for use and you aren’t worried about nostalgic value, replace the microphone output connector (not-so-grand for RF) with a chassis mount BNC female jack- makes life so much easier if you want to tee in a counter or 50 ohm load or anything else semi-modern.

Introduction to the Signal Generator or a modulation signal. Signal generators are also often called signal sources or simply, sources. A signal generator allows you to output signals with various frequencies, amplitudes, and time durations.

Many signal generators even allow you to modulate frequency, amplitude, and phase signals.Barnes and Heim: A High-Resolution Ammonia-Maser-Spectrum Analyzer 5 If the input signal is of the form V(t) = vo cos r$(t), (2) where +(t) is some function of time, then the current be- comes I = g(V0 cos r$) vo cos 4.

Since cos 4 is an even function of 4, g(ITo cos 4) is also an even function of 4, and therefore I is an even func- tion of 4.
