l input circuit to permit tuning. The complete apparatus necessary to measure Tn and yio is shown inFig. 16. This equipment, save for the details already discussed, is quite con-ventional in every respect. 636 BELL SYSTEM TECHNICAL JOURNAL In order to measure yn , the output coaxial line was short-circuited at apoint an integral number of half-wave-lengths from the grid-anode terminalsof the tube. The admittance measured in the input line could then be usedin computing ^n . To measure J22, the procedure was reversed, the inputline being shorted, and the corresponding admittance being measured in theoutput line. In either case the normalized line admittances were measuredby the standard procedure of determining the standing wave ratio in theline and locating the position of the standing wave minimum with respectto the equivalent terminals of the tube. The transfer admittances were measured with the equipment shown inFig. 17. The equipment shown here has been fully described in a recent

The output of a signal oscil-lator is divided into two portions. One portion is applied to a balancedmodulator where it is modulated by an audio-frequency signal. The sup-pressed-carrier, double-sideband signal from the modulator is applied to theinput circuit of the triode. Probes are provided for sampling the voltagesVi and F2 at points an integral number of half wavelengths from the inputand output gaps of the tube respectively. The other portion of the oscillatorpower is fed through a calibrated phase shifter and is applied to a crystaldetector in the manner of a local oscillator of a double-detection receiver.The signal samples at V i and V 2 are then alternately applied to the crystaldetector where they are demodulated by the action of the homodyne carrier.In each case the phase shifter is adjusted so that the audio signal d

Me^jU FREED COMPONENTS /o^ HI-FIDELITY AMPLIFIERPROVIDE IMPROVED PERFORMANCE This Freed circuit incorporates several changesfrom the original Williamson circuit to provide op-timum performance at high and low frequency ex-tremes. It is rated at 10 watts with triode connectedoutput tubes. However, by connecting the screengrids of these tubes to taps provided on the FreedKA-10 output transformer, it is possible to doublethe power output for a given distortion percentage. Recommended power supply is choke-input typewith a two-section L-C filter to maintain constantD.C. output and to improve filtering to the voltageamplifiers. Other high quality Freed components Include minia-ture audio transformers, magnetic amplifiers, toroidalinductors, subminiature encapsulated pulse trans-formers, precision filters and a complete line ofprecision laboratory test instruments. Complete cata-logs are available to engineers requesting same onfirm letterheads.

Install a CoAx Ratiometer in the line between your trans-mitter and antenna (or tuner) and stop guessing at a propermatch. In this new device, well-established principles areapplied to produce a unique answer to the problem ofmeasuring standing wave ratios. The result is a design ofexceptional accuracy and simplicity. There are no condensors to balance, no resistors in lineto dissipate your power. The unit handles frequencies from2 to 200 MCS, power loads from 10 to 1000 watts (so itcant be overloaded). Rugged construction, but so compactit can easily be permanently installed insi
