Title: Improvements relating to testing instruments for radio transmitting apparatus
IPC: G01R29/06
Filed: 1930-08-22
Abstract: 347,991. Measuring modulation of waves. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. -(Assignees of Ring, A. D. ; of Federal Radio Commission, Washington, U.S.A.) Aug. 22, 1930, No. 25163. Convention date, Aug. 22, 1929. [Class 37.] The percentage modulation of a radio transmitter is indicated by rectifying the modulated wave and comparing the alternating component with the direct component of the rectified current. The modulated wave is picked up by a tuned circuit 5, 7 and is passed through a rectifier 17 into two parallel circuits 10, 11 of which 10 includes a choke 12 for blocking alternating components, whilst 11 includes a condenser 14, for blocking direct current. Comparison of the readings of milliammeters 13, 16 in the respective circuits 10, 11 indicates the percentage modulation. Preferably the meter 16 is omitted and the value of the current in the path 11 is determined by including therein a resistance 15 and by tapping off a variable fraction of the voltage across this resistance and applying it to the grid circuit of a valve rectifier 29. This valve operates near the point of zero plate current, and a milliammeter 35 in its plate circuit gives a measure of the current in the circuit 11, 15, &c. As an alternative method of operation, the reading of the meter 35 may be kept constant by adjustment of the tapping switch 25, the control dial of which may be suitably calibrated. The grid bias for the valve 29 may be taken from a resistance 26 in the filament circuit of the rectifier 17. The carrier wave in the output circuit of rectifier 17 is byepassed by a condenser 28 and is blocked by a trap circuit 18. A resistance 19 is also included in a common portion of the parallel circuits 10, 11.
