While the vessel is docked the presentation of the pier is distorted near the center of the PPI with the pier appearing to bend in a concave fashion. This is a primary indication of what?
The deflection coils need adjusting. (22% chose this)
The centering magnets at the CRT neck need adjusting. (17% chose this)
The waveguide compensation delay line needs adjusting. (53% chose this)
A circuit card in a RADAR system has just been replaced with a spare card. You notice the voltage level at point E in Fig. 8F12 is negative 4.75 volts when the inputs are all at 5 volts. The problem is:
The 25 K resistor is open. (11% chose this)
The 100 K resistor has been mistakenly replaced with a 50 K resistor. (14% chose this)
The op amp is at the rail voltage. (11% chose this)
The 50 K resistor has been mistakenly replaced with a 25 K resistor. (64% chose this)
In the circuit contained in Fig. 8F12, there are 5 volts present at points B and C, and there are zero volts present at points A and D. What is the voltage at point E?
When monitoring the gate voltage of a power MOSFET in the switching power supply of a modern RADAR, you would expect to see the gate voltage change from "low" to "high" by how much?
In the circuit shown in Fig. 8A4, U5 pins 1 and 4 are high and both are in the reset state. Assume one clock cycle occurs of Clk A followed by one cycle of Clk B. What are the output states of the two D-type flip flops?
