For average pulse input powers greater than 25 watts the heater voltage must be reduced within 3 seconds after the application of h. t. according to the following schedule: Heater Voltage : Ef 6.3 1 - Pi [V] 100 Pi :Input Power (Average)[W] Note 2: Measured at peak anode current 8.0A 1-1,Fukuoka 2-chome, Fujimino-city Saitama-prefecture 356-8510 Japan Phone:049-278-1298 Fax :049-278-1419 Technical Information Rev.6 Note 3: Any overshoot of the anode current is not acceptable. The impedance of this magnetron is the same as current magnetron excluding the transient impedance. This means that the additional reactance should be required for adjustment the anode current wave form, if this magnetron will be installed into the similar modulator circuit as before. 1-1,Fukuoka 2-chome, Fujimino-city Saitama-prefecture 356-8510 Japan Phone:049-278-1298 Fax :049-278-1419
