Pulsed-RF Measurement Types
Figure 2 shows three major types of pulsed-RF measurements. The first two
are pulsed S-parameter measurements, where a single data point is acquired
for each carrier frequency. The data is displayed in the frequency domain
with magnitude and/or phase of transmission and/or reflection. Average
pulse measurements make no attempt to position the data point at a specific
position within the pulse. For each carrier frequency, the displayed S-parameter
represents the average value of the pulse. Point-in-pulse measurements result
from acquiring data only during a specified gate width and position (delay)
within the pulse. There are different ways to do this in hardware, depending
on the type of detection used, which will be covered later. Pulse profile
measurements display the magnitude and/or phase of the pulse versus time,
instead of frequency. The data is acquired at uniformly spaced time positions
across the pulse while the carrier frequency is fixed at some desired frequency.
