f. Observe the peak-to-peak voltage of the 1500 CPS signal (Figure 44).
Figure 44.
1500 CPS signal.
g. Adjust the 1500 CPS level control (R-3036) for a 50 V peak-to-peak
signal on the oscilloscope.
h. Disconnect the oscilloscope from the receiver.
i. Push in the R-981/FPN-40 and latch the release handles (Figure 39).
4.
You have completed the 1500 CPS voltage level of radar set AN/FPN-40.
In doing so, you have ensured that the 1500 CPS sine wave, produced by the
oscillator circuit, is at the correct voltage level to be applied to the
data take-off resolvers.
