15.5 Sweep Configuration
Access: "Sweep"
Remote commands to control the measurement:
●
Chapter 17.14.5, "Sweep Control", on page 293
The sweep menu provides settings to control the measurement and the way data is
captured.
Selecting the measurement mode
The measurement mode defines how often the data is demodulated.
In continuous mode, the R&S FPC demodulates the signal over and over until you stop
it deliberately. The measurement results are updated accordingly.
In single mode, the R&S FPC demodulates the signal once and then stops without
updating the results any longer. Another measurement starts only when you deliber-
ately initiate it.
1. Press the "Sweep" key to open the sweep menu.
2. Select the "Continuous Sweep" menu item.
The R&S FPC demodulates the signal continuously.
You can interrupt a continuous measurement by selecting the "Continuous Sweep"
menu item again.
3. Select the "Single Sweep" menu item.
The R&S FPC demodulates the signal once and displays the results of that mea-
surement.
