MEASURE MENU VS VIEW MENU. The choices on these two menus
are very similar, however the action performed by the instrument is quite
different. Selecting any of the choices on the Measure menu will cause
the instrument to initiate a measurement and acquire a new set of data
points and perform the selected result processing. Selecting any of the
choices on the View menu will cause the instrument to perform the
selected calculations on the currently acquired data.
The notable difference between the selections on the Measure and View
menus is that the View menu also offers the choice to compute an FFT of
the data currently on the display.
Note that data files that are saved and subsequently recalled can be
"re-processed" to compute other results using the View menu.
The display is now showing Frequency vs. time. This signal is a 100 MHz
carrier with sinusoidal frequency modulation (approximately a 11 kHz
rate and a 500 kHz p-p deviation). You can re-process the data to display
phase power spectral density by performing the following step.
