User Manual 1178.4130.02 ─ 02
In continuous mode, the R&S
FPC1000 demodulates the signal over and over until you
stop it deliberately. The measurement results are updated accordingly.
In single mode, the R&S
FPC1000 demodulates the signal once and then stops with-
out updating the results any longer. Another measurement starts only when you delib-
erately initiate it.
1. Press the "Sweep" key to open the sweep menu.
2. Select the "Continuous Sweep" menu item.
The R&S
FPC1000 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
FPC1000 demodulates the signal once and displays the results of that
measurement.
11.6 Limits
Access
(limits menu): "Lines"
Remote commands to configure limits:
●
Limits are an analysis tool that allows you to compare the measured signal levels to
signal specifications, and determine if the measured signal characteristics comply to
these specifications. You can define limits for all numerical results available in the AM
and FM result summary.
Note that you can define limits only for the numerical results. The graphical results of
the analog demodulation do not support limits or limit lines.
To use limits, you have to create a set of limit values with the "AM Limits" and "FM Lim-
its" tools available with the R&S
InstrumentView software. The functionality of these
tools allows you to specify limits for each result type and whether the result should be
checked against the limit or not.
For more information about creating, editing and transferring limits, refer to the user
manual of the R&S
InstrumentView.
Selecting and evaluating limits
1. Press the "Lines" key top open the limits menu.
2. Select the "Select Limits" menu item to open the file manager.
3. Navigate to the dataset that contains the limits you want to use.
Make sure to select a dataset that is compatible to the current measurement: limits
for AM measurements have file extension
.amlim
, those for FM measurements
have the file extension
.fmlim
.
