Figure 8-2 shows a block diagram of the test setup. ESG #1 produces a
pulsed FM signal by using an external pulse signal. The external pulse
signal is connected to the front of the ESG #1 to the EXT 2 INPUT to
control the pulsing. The pulse signal is also used as the trigger signal.
The oscilloscope is useful for illustrating timing interactions between
the trigger signal and the gate. PSA
Gate View could be used in place of
the oscilloscope.
Using this measurement setup allows you to view all signal spectra on
the spectrum analyzer and all timing signals on the oscilloscope. This
setup is helpful when you perform gated measurements on unknown
signals.
