synchroscope|ˈsɪŋkrəʊskəʊp|
[f. synchro- + -scope.]
1. Electr. Engin. An instrument for indicating any difference in frequency or phase between two alternating voltages.
1908V. Karapetoff Exper. Electr. Engin. xxi. 494 It only remains..to bring the machine into phase with the voltage at the bus-bars. This is done either by means of properly connected incandescent lamps..or special instruments, so-called synchroscopes. 1952H. F. Banks Electricity I. xvii. 268/2 A..usually adopted method of paralleling two alternators is by means of the rotary synchroscope. 1981T. Wildi Electr. Power Technol. xix. 364/2 Observe the phase angle between E0 and E by means of a synchroscope.
2. Electronics. (See quot. 1945.)
1945Electronic Industries Sept. 226 Synchroscope, an oscilloscope on which recurrent pulses or wave-forms may be observed, which incorporates a sweep-generator that produces one sweep for each pulse, regardless of frequency, thus allowing no more than one cycle to be viewed on the screen. 1947R. Lee Electronic Transformers & Circuits ix. 257 This curve is observed by connecting the vertical plates of a synchroscope..across the transformer output winding. 1953Electronic Engin. XXV. 229/1 Another specialised oscilloscope (synchroscope) is provided to display all details of the television waveform. |
