The new decades require an 80-volt negative-going pulse of 1 microsecond maximum rise time for driving purposes, somewhat lower than the driving voltage of previous units because of reduced stray capacities in the new layout. If faster rise time is available, somewhat less amplitude can be vised since the driving pulse is applied to a differentiating network of approximately 100 rami in series with 15,000 ohms. Each decade provides an 80-volt negative-going output step for driving another...

Two New Transformers for Measurements on Balanced Systems

Audio Bridging Transformer

SINGLli-tNDHD electronic measuring instruments such as electronic voltmeters, distortion meters and wave analyzers can be used quite successfully to make measurements on balanced systems by introducing a high-performance transformer between the balanced system and the single-ended instrument. To enable single-ended -bp- instruments to be used in such applications, two new halanced transformers have been designed. One is especially useful in carrier-communications work and operates over a range...

New MC to KMC Coaxial Crystal Detector Mount

Counters, p. 2 New Matthing Transformer j, p 4 ANEW general-purpose coaxial crystal detector mount has been developed to operate over the entire range from 10 megacycles to 12.5 kilomegacycles. Since this range is essentially the complete range practical for coaxial systems, this one mount can he used for all ordinary coaxial-system detector applications. A feature of the mount is that it has been designed to have reduced sensitivity to variations in crystal characteristics. The new mount has a...
