Dear readers , This afternoon I wanted to test my YH1195 TWT . I'm powering the PSU with 24V and when turning on I have +/- 0,3amps of current . After +/- 3 to 4 minutes the current drops to 0,05 amps . When feeding the TWT with 0dBm nothing happens , it's like the TWT went in to protection mode . Turning the DC supply off and on again I have the same scenario again . Could anyone help me out ? Thanks and best regards, Kenny ON4DPX
