DictionarySeetimerecovery time
recovery time[ri′kəv·ə·rē ‚tīm] (electronics) The time required for the control electrode of a gas tube to regain control after anode-current interruption. The time required for a fired TR (transmit-receive) or pre-TR tube to deionize to such a level that the attenuation of a low-level radio-frequency signal transmitted through the tube is decreased to a specified value. The time required for a fired ATR (anti-transmit-receive) tube to deionize to such a level that the normalized conductance and susceptance of the tube in its mount are within specified ranges. The interval required, after a sudden decrease in input signal amplitude to a system or component, to attain a specified percentage (usually 63%) of the ultimate change in amplification or attenuation due to this decrease. The time required for a radar receiver to recover to half sensitivity after the end of the transmitted pulse, so it can receive a return echo. (nucleonics) The minimum time from the start of a counted pulse to the instant a succeeding pulse can attain a specific percentage of the maximum value of the counted pulse in a Geiger counter. recovery time
