In this case two signal generators were used: the first one generates the 50 % duty cycle for the pre-amplifier, and the second one generates the variable duty cycle for the cascade boost converter.
I fed the signal into a pre-amplifier circuit and then into an audio mixer and P.
The model MS2711D Spectrum Master[TM] is a handheld spectrum analyzer that delivers improved sweep speed, and is designed with a built-in pre-amplifier that increases the analyzer's sensitivity and dynamic range.
Both the positive ions and the pre-amplifier resistor help to reduce the effective potential preventing avalanche.

DWDM EDFA 40 channel BA model amplifier is ideal for applications in Booster, DWDM optical system or pre-amplifier online amplifier.
The pre-amplifier is rated at 32 GHz; the trigger is rated to 20 GHz, which delivers a nearly two-fold drop in noise to 2.
The Model 5660 comb generator has a pre-amplifier, and it works with sine wave inputs ranging from 500 MHz to 3 GHz, producing usable harmonics to greater than 50 GHz.
2) Signal/noise ratio -- To minimize the noise factor, in a lot of new systems the distribution of the gain of the amplification chain has been modified, increasing the power delivered by the pre-amplifier, and decreasing the gain at the TWT stage.
The device also features a rechargeable battery and AC power use, backlit LCD display, calibration at common laser wavelengths selectable from 350 nm to 1100 nm, and an analog output providing the signal measured right after the pre-amplifier.
