The Agilent CSA’s optional modulation
measurement suite provides functional and
parametric analysis of AM and FM.
Whether you’re making modulation depth or
frequency deviation measurements for AM or FM
devices, the Agilent CSA spectrum analyzer gives
you the full range of metrics you need. The detailed
measurement information – including deviation,
modulation rate, distortion, SINAD, and carrier
power – ensures a full understanding of the modu-
lation characteristics. Both time domain and
frequency domain views of the data allow you to
analyze the signal quickly from different perspectives.
The tune-and-listen option capability lets you hear
the signal and classify it based on its audio qualities.
Analyze pulsed signals
The CSA clearly and easily displays pulsed signals
in the frequency domain. You can measure the
amplitude difference between a CW signal and a
pulsed signal. The example to the right shows the
Sinx/x of a pulsed signal along with the associated
CW signal.
