SUMMARY
The theoretical power of a 1Vpp sine wave at 1 MHz, with 200 cycles over a 100 ms interval into a 50Ω load, is calculated to be 5 microwatts. This is derived from the continuous power of 2.5 milliwatts for the 50Ω load, which translates to 0.5 x 10^-6 joules per cycle. The calculations confirm that the power output remains consistent across the specified parameters, demonstrating the efficiency of the waveform when amplified by a 55dB amplifier.
