  • Hi Tony,

    I repeated the measurement in my lab using the ADL5370 EVB with no modifications.

    I get much faster turn-on/off time. (<30 us)

    Spectrum analyzer and scope provide very similar results.

    I used an LDO as power supply and the instruments were triggered with the enable signal of the regulator.

    The 5V supply takes about 150 us to settle.

    Please have a look at the attached images.
