The X-Band microwave motion detector was moved to 10.25GHz. We explore the output of the HP x421A detector diode attached to the HP x532A X-Band wavemeter, and verify the frequency of operation.

The X-Band microwave motion detector was moved to 10.25GHz in Part 1, and we explored the diode output in part 2. In part 3, we examine the pulse width and pulse repetition rate with the oscilloscope, and draw a conclusion about the diode modulation.
