7.2.1 Basic Measurements
Basic measurements are common sweeps in the time or frequency domain which pro-
vide an overview of the basic input signal characteristics.
If no other measurement function is selected, or if all measurement functions are
switched off, the R&S FPL1000 performs a basic frequency or time sweep.
After a preset, a frequency sweep is performed.
Use the general measurement settings to configure the measurement, e.g. via the
"Overview" (see Chapter 7.1, "Configuration Overview", on page 94).

Frequency Sweep
A common frequency sweep of the input signal over a specified span. Can be used for
general purposes to obtain basic measurement results such as peak levels and spec-
trum traces. The "Frequency" menu is displayed. This is the default measurement if no
other function is selected.
Use the general measurement settings to configure the measurement, e.g. via the
"Overview" (see Chapter 7.1, "Configuration Overview", on page 94).

Zero Span
A sweep in the time domain at the specified (center) frequency, i.e. the frequency span
is set to zero. The display shows the time on the x-axis and the signal level on the y-
axis, as on an oscilloscope. On the time axis, the grid lines correspond to 1/10 of the
current sweep time.
Use the general measurement settings to configure the measurement, e.g. via the
"Overview" (see Chapter 7.1, "Configuration Overview", on page 94).
