Figure 18 shows how the narrowband filter path affects pulsed-RF signals
by looking at the central frequency tone of the pulsed-RF signals with 200
ns pulse width and 2 us PRI. In Figure 18, the top window shows the PNA-
X’s 500 Hz IF filter response with the wideband IF path. The bottom window
shows the narrowband filter path, which removes some of the undesired
spectrum of the pulse-RF signals with 30 kHz crystal filter.
