Abstract: A picture display device comprising a power supply circuit and a line deflection circuit. The power supply circuit comprises an inductance, and a switch switching at line frequency, the inductance forming part of a resonant network during the cut-off period of the switch. The line deflection circuit comprises a switch which also switches at line frequency and a line deflection coil which during the cut-off period, the retrace period, of this switch forms part of a resonant network which also comprises an inductance. A transformer winding is coupled to one of the inductances. Across this transformer winding there are pulses which are rectified for generating a supply voltage for a variable load. To reduce the internal impedance of the source formed, for example the high voltage source, the cut-off period of the supply circuit substantially coincides with the retrace period and the device comprises a connection for connecting at least during the conduction time of the rectifier a point of the transformer winding or of a winding coupled thereto to a point of the inductance not coupled to the transformer winding or of a further winding coupled to the said inductance, the said connection being substantially currentless in the non-loaded state of the source.

Abstract: An RF wattmeter is disclosed of the type using an "insertion-type" pick-up element to produce a voltage wave signal corresponding to the measured power in the coaxial transmission line (11). The induction loop (21) in the pick-up element is connected to a principal detector (25), and a secondary detector (30) is connected in opposition to the principal detector (25). Both detectors are located in close proximity to each other and are subject to the same diode thermal environment. A sine wave generator supplies a wave signal to the secondary detector in opposition to the wave signal supplied to the principal detector from the inductive loop (21). The d.c. portion of the resulting signal representing the difference between the opposed signals is integrated (40), and the integrated output is used as the amplitude in the generated sine wave (32). When the circuit is in balance, the integrated output matches the amplitude of the inductive wave form and can be used as an output indicating (43) measured power in the coaxial transmission line (11).
