Instruction
Connect the signal generator to the RF IN
connector and turn on the signal generator's
AM and RF output.
Set the signal generator to 100 MHz, AM; AM
depth, 50%; amplitude, –15 dBM; modulation
rate, 1 kHz.
Turn on the AM demodulation analysis
function.
Set the carrier frequency of the source.
Set the attenuation state to auto.
Set the Y scale.
Set the AM depth limit and turn on the limit
function.
