2M214 MODEL MAGNETRON SPEC. Rev. No. 0 Notes (continued) :
(6) pulling figure is the difference between the maximum and the minimum frequency of oscillation that occurs when the phase of the reflection coefficient of the load is varied over the λg/2. The sink phase is defined as the phase to give maximum change of the frequency and to give the same oscillating frequency as that at matched load. In both cases, with the variation of phase, the load VSWR should be held at the stated value (σ L=4) (7) Measured with Narda type 8110 radiation monitor. (8) Measured with the microwave oven accepted by both parties. (9) Mechanical strength (A) : The antenna cover should not be drawn out when it is pulled to the direction of antenna axis with stated force. Mechanical strength (B) : Any degradation of breakdown voltage should not be observed after pressing the filter box with standard test finger with stated force. Mechanical strength (C) : The terminals should withstand stated pulling force to the direction of terminal axis. (10) Any instability such as moding if run-away should not be observed at any load phase. (11) Filament terminal with in-phase mark (“F”) should be connected to the filament transformer so as to have the same polarity as anode. (12) Test conditions are as follows. Amplitude : 2 mm (peak to peak) Frequency : 25 Hz Time of vibration : 10 minutes ( for each of three directions) (13) Distance from reference place of magnetron (antenna axis) to mismatched point should be 27.6 inches (700mm) min. (14) Should not discharge continuously. (15) Load match may vary to higher VSWR in application, but must be reviewed by LG with regard magnitude, phase and dwell time. (16) Microwave Oven : LG Standard Model Method of measurement : open field. Load condition : volume of water : 250 ml in 500 ml beaker position of load : center (17) Maximum 57 dBpW at 80% of production.
