3.3.6 Amplitude Stability - At standard conditions, after a 2-minute warm-up period,
and with the power supply on full power, each channel shall maintain its voltage amplitude
within a tolerance of + 10 percent and -20 percent for 15 minutes.
3.3.7 R. F. Voltage - By adjusting the screen potentiometers, it shall be possible to
raise the r-f voltage for each channel to 12 volts rms measured across a 60-ohm load in series
with a l-microfarad capacitor at the output of the charging gear (pin B of J1202).
3.3.8 Output Waveform - Harmonic distortion shall not exceed 25 percent on the fre-
quencies of channel numbers 5, 6, 7, and 8. Up to 40 percent distortion is acceptable on the
other frequencies (channel numbers 1, 2, 3, and 4).
3.4 Detail Requirements -
3.4.1 Amplifier-Power Supply AM-2014/Aww- 1- The amplifier-power supply shall
meet the following requirements:
3.4. 1.1 Function - The amplifier-power supply shall provide the voltages required by
the oscillator circuits of Radio Frequency oscillator O-562/AWW- 1. It shall also supply the
d-c and amplified r-f fuze charging outputs of the fuze function control set.
3.4.1.2 Form Factor - The dimensions of the amplifier-power supply shall not exceed
3 3/4 inches wide by 8 7/8 inches high by 11 7/16 inches long.
3.4.1.3 Weight - The weight of the amplifier-power supply shall not exceed 12 7/8
pounds.
3.4.1.4 Contents of Unit - The amplifier-power supply shall contain the following
circuits.
(1) Power Supply Circuit - The power supply circuit shall provide the unregulated
voltages required by the voltage regulator circuit and the cathode follower circuit.
(2) Voltage Regulator Circuit - The voltage regulator circuit shall provide
regulated plate voltages for the amplifier circuit tubes (located in the amplifier-power supply)
and the oscillator circuit tubes in Radio Frequent y Oscillator O- 562/AWW- 1. It shall also
supply the regulated d-c fuze charging outputs of the fuze function control set.
(3) R-F Amplifier Circuit - The amplifier circuit shall amplify the r-f fuze
charging signals provided by the Radio Frequency Oscillator O- 562/AwW- 1. The amplifier
circuit shall contain a cathode follower circuit to provide a low impedance output with
minimum r-f signal distortion.
3.4. 1.5 Controls - The front panel of the amplifier-power supply shall contain the fol-
lowing screwdriver adjusted controls.
.
(1) RF BIAS Control - The RF BIAS control shall be used to adjust the -55 O. 3
volt d-c grid bias on the cathode follower tubes. The control shall be labeled RF BIAS ADJ 55V.
(2) RF SUPPLY Control - The RF SUPPLY control shall be used. to adjust the
+300 1.5 volts d-c required by the amplifier circuit (in the amplifier-power supply) and the
oscillator circuits of Radio Frequent y Oscillator O- 562/AWW- 1. The control shall be labeled
RF SUPPLY ADJ 300V.
(3) OUTPUT Control (300V) - This OUTPUT control shall be used to adjust the
300 volt d-c fuze charging output of the fuze function control set. The control shall be labeled
OUTPUT ADJ 300V.
(4) OUTPUT Control (195v) . This OUTPUT control shall be used to adjust the
