Downloaded from https://www.everyspec.com MIL-STD-1311D m. Klystrons. Shall be tested for controlling-electrode voltage, power output, and tuning range. After rough-handling test, the controlling electrode voltage and power outputs shall not have changed from their initial values by more than the amount specified. The tubes shall pass the frequency-range test specified on the TSS. Tubes using an external cavity shall operate within the frequency specified. n. M-type backward wave. Power output and voltage tuning, conformance inspection, part 1. o. Magnetrons. Shall pass the initial test requirements for pulse voltage, stability, frequency, and bandwidth.
These tests shall be performed under the oscillation conditions for those parameters specified in the life-test end points. p. Negative grid (microwave). Power Osc or transconductance, conformance inspection, part 1. q. Noise source. Conformance inspection, part 1: Excess noise ratio. r. Phototube. Anode sensitivity. s. Power or transmitting tubes (except hydrogen diodes). Shall pass the anode current, cutoff, and operation tests when these tests are specified on the TSS. Gas rectifiers shall be subjected to the operation tests, a minimum 24 hours after this rough-handling test has been made. t. Pulse modulator, hydrogen.
Shall pass the time jitter and operation tests when these tests are specified on the TSS. These tests shall be made a minimum of 24 hours after the rough-handling test has been made. u. Pulse modulators, vacuum. Grid pulse operation. v. Radiation counter. 6201 Background contamination. 6211 Starting voltage. 6216 Relative plateau slopes. w. Receiving tubes. Shall be within the limits of the following when specified as conformance inspection, part 1: heater- cathode leakage, anode current, cutoff, power output, transconductance, anode resistance, ac amplification, and conversion transconductance. Rectifiers shall pass the operation and heater cathode insulation test when specified on the TSS.
Gas rectifiers shall be subjected to the operation test a minimum of 24 hours after the rough-handling test has been performed. x. Thyratrons (excluding hydrogen thyratrons). Shall pass the anode voltage, grid voltage, and operation tests when these tests are specified on the TSS. These tests shall be made a minimum of 24 hours after the rough-handling test has been made. y. TWT and O-type backward wave. Conformance inspection, part 1: Noise figure, gain, saturated power. z. Vidicon. Resolution, spurious signal, cutoff. aa. Voltage regulators. Shall be within the limits of the ionization-voltage test. Only those ionization tests which are conformance inspection, part 1 tests, shall be made.
bb. Voltage regulator: Corona discharge. Conformance inspection, part 1: 3347 Ionization voltage. METHOD 1136C 1136-2 28 March 1975
