An Electronic Time Interval Meter with Magnetron Beam Switching Tubes.

摘要

An electronic time interval meter employing the NIXIE in-line readout tubes and magnetron beam switching tubes has been designed and constructed. The device employs a tuning fork oscillator as a time base, and has an over all accuracy of 1 part per 20,000 + or - 1 count. The resolution of count is one millisecond. Maximum counting interval is 99.999 seconds. Input power supply requirements are 117 volts, 60 cycles, a. c., single-phase at 0.54 amperes. A remote readout accessory was also developed employing five miniature NIXIE tubes and is used to facilitate photographing data output on an instrument panel. (Author)
