The R&S
FSV/A shows the currently selected resolution bandwidth in the diagram
header.
9. Configure the traces for the initial EMI measurement.
a) Select [TRACE] .
b) Select "Trace Config" to configure two traces.
c) Define the detectors to use for the initial measurement. Select the peak detec-
tor for trace 1 and the average detector for trace 2.
The peak detector ensures that the detected peak levels in the frequency range
covered by one pixel are displayed.
The R&S
FSV/A now displays two traces. Trace 1 shows the peak values, trace 2
shows the average values.
10. Increase the number of sweep points for the EMI measurement.
a) Select [SWEEP] on the front panel.
b) Select the "Sweep Config" .
c) Set the number of "Sweep Points" to
200000
.
11. Select [AMPT] , then select the "Amplitude Config" and, in the "Amplitude" dialog
box, select
V
as the "Unit".
Performing the measurement
1. Configure the EMI measurement markers. In this example, we use 6 markers.
a) Select the "Marker Config" .
b) Activate six normal markers.
c) Set markers 1 to 3 on trace 1. Set markers 4 to 6 on trace 2.
d) For each of these markers, select the "CISPR AV" detector to be used for the
"Final Test", i.e. the subsequent EMI measurement at the marker positions.
2. Select a limit line to check the marker results against.
a) Select [Lines] and then the "Lines Config" , then select the "Lines Config" tab.
b) In the "Line Config" dialog box, select the "View Filter" option: "Show Compati-
ble".
All limit lines that comply with the following conditions are displayed in the over-
view:
● Stored in the
limits
subfolder of the main installation folder of the instru-
ment
● File extension
.LIN
● Compatible to the current EMI measurement settings
c) In the overview, click the "Check Traces" setting for the
EN55011A
limit line.
d) Select trace 1 to be included in the limit check. (Trace 2, which is defined as
the average, is always lower than trace 1, which contains peak values.)
3. Select [RUN SINGLE] to start a new EMI measurement.
If activated, a peak search is performed. For each active marker, a final measure-
ment is performed using the specified detector for the specified dwell time.
