12. Optionally, select the "Marker Demod Config" to configure continuous marker
demodulation.
Demodulation begins immediately with the next measurement. During the initial
measurement, demodulation is performed for the entire measurement span; during
the final measurement only the detected peak marker positions are demodulated
(for the defined dwell time).
13. 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" so that the distance between two sweep
points is smaller than RBW/3.
14. Optionally, select or configure limit lines 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) Select the "Check Traces" setting for a limit line in the overview.
d) Select the trace numbers to be included in the limit check. You can assign the
same limit line to several traces.
15. The default unit dBm is not suitable for EMI measurements. Define a suitable unit
for the measured values, or select a transducer.
To change the unit:
Select [AMPT] > "Amplitude Config" > "Unit".
To select a transducer:
a) Select [SETUP].
b) Select "Transducer".
c) In the "Transducer" dialog box, set the "View Filter" to "Show Compatible" to
determine the available transducers for the current EMI measurement setup.
d) In the overview, select the "Active" setting for a transducer line.
16. 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. If acti-
vated, the signal is demodulated at the active marker positions.
The specified traces to be checked are compared with the active limit lines. The
status of the limit check for the final measurement is indicated in the Result Sum-
mary.
