Embodiment Construction
[0032] The present invention will be further described in detail below in conjunction with a space traveling wave tube four-stage step-down collector.
[0033] Step 1 Description:
[0034] Connect the traveling wave tube power supply, the input signal input device and the output signal receiving device, set the working ratio of the traveling wave tube electron injection modulation power supply to 1%-5%, and set the traveling wave tube spiral flow safety threshold I h , given the recovery current indication value I of the stop voltage step-down sweep R .
[0035] For the measurement data of the traveling wave tube, the first step is to add power to the traveling wave tube and input signal input device and output signal receiving device. Make sure the TWT is working properly. In order to ensure safety, the TWT electronic injection modulation power supply is tested from a low duty ratio, and the duty ratio range of 1%-5% is selected here; the initial duty ratio is set to 5% in...
