10 Figure 1F.—Absorption wavemeter circuit. IN ANSWERING QUESTION 1-61, REFER TO FIGURE 1F. 1-61.   When you are using an absorption wavemeter to measure frequency, the greatest accuracy may be obtained by loosely coupling the pickup coil so that the indicator lamp burns (a) with what degree of brilliance (b) under what resonance condition? 1.  (a) Maximum brilliance (b) when tuned to the resonant frequency 2.  (a) Maximum brilliance (b) when not tuned to the resonant frequency 3.  (a) Dimly (b) when not tuned to the resonant frequency 4.  (a) Dimly (b) when tuned to the resonant frequency 1-62.   Which of the following instruments should be used to accurately measure a frequency in the shf range? 1.  Absorption wavemeter 2.  Resonant, cavity-type wavemeter 3.  Resonant, coaxial-line-type wavemeter 4.  Both 2 and 3 above 1-63.   In a cavity wavemeter, moving the plunger farther into the cavity space causes which of the following changes to (a) the cavity size and (b) the resonant frequency of the cavity? 1.  (a) Decrease (b) increase 2.  (a) Decrease (b) decrease 3.  (a) Increase (b) decrease 4.  (a) Increase (b) increase 1-64.   For which of the following purposes is a cathode-ray oscilloscope used? 1.  To measure microwave energy 2.  To visually analyze waveforms 3.  To provide frequency modulation 4.  To locate stray radio interference 1-65.   The synchroscope contains which of the following circuits? 1.  Retrace blanking circuit 2.  A wide band amplifier 3.  A trigger sweep 4.  All of the above THIS SPACE LEFT BLANK INTENTIONALLY.
