Pulsed-RF Measurements Overview
Two types of measurements are available with the pulse configuration. Each type of measurement
is described below.
Pulsed-RF S-Parameters versus Frequency
Making pulsed-RF measurements in the frequency domain is accomplished by synchronizing the
measurement process with the pulse so that the measurement is made at a single, user-specified
time during the pulse. At each frequency, the sources are tuned, the RF is turned on, then the
measurement is made after a certain delay. Figure 3-11 shows an example of this frequency domain
(point-in-pulse) measurement using the internal pulse output and the internal measurement
trigger. Each data point of the trace represents the response of the device to the pulsed stimulus at
the same interval after the pulse is turned on for internal triggering, or after the falling edge of the
externally-generated measurement trigger.
